That clicking sound from behind your Maytag refrigerator โ the one that repeats every few minutes and then goes quiet โ isn’t random. It’s a precise mechanical event: the compressor circuit trying to start, failing, and then pausing while the thermal overload protector resets before trying again.
Most people hear it for a day or two and assume the refrigerator is just being noisy. By the time the food starts warming, three or four hundred startup attempts have already occurred. Each one puts stress on the compressor motor windings. The window to act inexpensively โ a $15 start relay โ can close in 48 hours.
This article covers Maytag compressor failure across all five failure patterns:
- the failed start relay,
- the locked compressor,
- short-cycling from dirty coils or refrigerant loss,
- control board misdiagnosis,
- the decision framework for what’s DIY-appropriate versus what requires an EPA-certified technician.
Applies to Maytag refrigerators including the MFI2569YEM0 French-door and similar models.
The Click That Means the Compressor Won't Start
Cause-Effect: Failed Start Relay โ Compressor receives no start signal. Clicks every 2โ5 minutes. Never runs. No cooling.
The start relay is a small component โ about the size of a matchbox โ plugged directly onto the compressor’s side terminals. Its function is narrow and critical: it energizes the start winding for the fraction of a second the compressor needs to reach running speed, then drops out of the circuit.
When the relay fails โ either from a broken internal connection or a failed PTC (positive temperature coefficient) element โ the compressor motor never crosses the threshold to self-sustaining operation. It draws current, trips the thermal overload, and waits for the reset. That wait is the silence you hear between clicks. Then the cycle repeats.
The Shake Test โ Valid DIY Diagnostic
- Unplug the refrigerator.
- Locate the start relay — on most Maytag models, the compressor sits at the lower rear of the unit behind a panel; the relay plugs directly onto the compressor’s side terminals.
- Pull the relay straight off — no tools required on most Maytag configurations.
- Hold it next to your ear and shake it firmly
A rattle means the internal connection is broken โ the relay has failed. No rattle doesn’t clear the relay entirely, but shifts the diagnostic probability toward the compressor motor itself.
Multimeter Confirmation
Set a multimeter to resistance (ฮฉ). Probe the start and run terminals on the relay body. A functioning relay reads near zero โ a closed circuit. A failed relay reads OL (open). This test takes under two minutes.
Start relays for Maytag refrigerators typically cost $10โ$40. Replacement requires no tools, no disassembly beyond the rear panel access. If the relay rattles or tests open โ replace it before concluding anything else is wrong. It’s the fastest, cheapest confirmation in compressor-circuit diagnosis.
If the relay tests fine and the clicking continues unchanged: the compressor motor itself has failed.
The Locked Compressor โ When the Motor Can't Turn
Cause-Effect: Mechanically Seized Compressor โ Motor draws full current, immediately trips thermal overload. Loud hum for 1โ3 seconds, then silence. Unit never cools.
A locked compressor is mechanically seized โ internal components have stopped turning, typically from lubrication failure, contamination, or advanced wear. The motor windings energize and try to drive rotation. They can’t. The thermal overload trips immediately to prevent the winding from burning.
Repair data for Maytag refrigerators documents locked compressor as the cause in approximately 66% of compressor replacement cases. It’s the most common reason a Maytag unit stops cooling entirely without a gradual decline.
Distinguishing a Locked Compressor from a Bad Start Relay
These two failures can sound similar. The differences are specific:
Symptom | Start Relay | Locked Compressor |
Sound | Brief click, then silence | Distinct hum (1โ3 sec), then a thud or click |
Rhythm | Every 2โ5 minutes, consistent | Every 5โ10 min; hum audible |
Relay shake test | Rattles | Silent โ relay tests fine |
Floor vibration | None | Faint vibration when hum occurs |
After relay replacement | Resolves | Clicking/humming continues |
A locked compressor cannot be repaired in the field โ there is no DIY path. Accessing the sealed system, recovering the existing refrigerant, removing the compressor, and installing a replacement requires an EPA-certified technician with Section 608 certification and refrigerant recovery equipment. Handling refrigerant without that certification is a federal violation under EPA regulations, not a formality.
Warranty note: Maytag’s standard warranty covers the compressor part for 10 years from the original purchase date. Labor โ diagnosis, refrigerant recovery, installation, and recharge โ is typically not included. Confirm coverage by cross-referencing the unit’s serial number with the original purchase date before authorizing any repair.
Short-Cycling โ The Compressor Runs but Can't Keep Up
Cause-Effect: Compressor Short-Cycling โ Starts and stops too frequently. Interior temperature rises slowly. Unit runs constantly but never reaches target temperature.
A Maytag compressor running in short bursts โ on for 4โ5 minutes, off for 2, back on again โ is being stopped before it can complete a full cooling cycle. Three separate causes produce this same pattern:
1. Dirty condenser coils
The condenser coils release refrigerant heat into the surrounding air. When they’re coated with dust, pet hair, and debris โ common in Atlanta homes with HVAC systems, pets, and red clay dust โ the heat can’t escape. The compressor shell overheats, the thermal overload trips, and the cycle ends early.
Quick check: Pull the refrigerator away from the wall. On most Maytag models, the condenser is accessible through the lower front grille or the rear panel. If the coil surface looks like a dust-covered filter rather than bare metal fins, cleaning is the first step โ and may be the entire fix.
Clean with a vacuum brush attachment. Allow the unit to run for 24 hours and observe whether the cycling pattern improves.
2. Refrigerant loss in the sealed system
A refrigerant leak lowers the system pressure. The compressor can’t build sufficient high-side pressure to complete a refrigeration cycle and trips out early. Short-cycling from a refrigerant leak produces a specific additional symptom: the compressor housing runs noticeably hot to the touch (not just warm) shortly after it shuts down.
If coils are clean and the compressor shell is hot โ not warm โ within minutes of a short cycle, a refrigerant leak is active. This requires an EPA-certified technician to diagnose with gauges and handle safely.
3. Defrost system failure mimicking compressor short-cycling
Frost accumulation on the evaporator coils from a failed defrost system gradually reduces airflow. The compressor runs harder to compensate and eventually short-cycles from thermal overload. This is the most commonly misdiagnosed pattern โ it looks like a compressor problem but isn’t.
The diagnostic test is simple: unplug the refrigerator for 24โ48 hours and let the evaporator coils thaw completely. Plug it back in. If cooling returns normally for 3โ5 days before the pattern resumes, the defrost system failed โ not the compressor. See [Maytag temperature problems] for a full breakdown of defrost system diagnosis before any compressor-related repair is authorized.
The Control Board โ Rarely the Cause, Often the Guess
โ Cause-Effect: Faulty Control Board โ Compressor receives no run signal or receives intermittent signals. Erratic cooling, display errors, multiple systems failing simultaneously.
The electronic control board coordinates every compressor start, defrost cycle, and fan command. It can fail. When it does, the pattern is typically broader than a single symptom โ erratic fan behavior, display errors, and unpredictable cooling all appearing at the same time.
The clicking that control board failure produces differs from relay clicking: it’s slower, less rhythmic, and usually accompanied by other display or fan anomalies. Pure, rhythmic clicking every 2โ5 minutes with no other symptoms almost always points to the start relay, not the board.
Correct diagnostic sequence:
- Test and replace the start relay first — inexpensive, fast, and responsible for the majority of compressor-won’t-start cases.
- Verify 120V is reaching the compressor terminals — confirms the board is sending power.
- Only then evaluate the control board — and only with a multimeter test of its outputs, not a visual assumption.
Board replacement requires the OEM part number specific to the model. Maytag control boards are not interchangeable across product lines. A board ordered by model description rather than confirmed part number is a common and expensive error.
DIY vs. Professional โ What's Actually Realistic
The compressor circuit spans a range of accessibility. This table is a genuine decision framework โ the start relay is legitimately DIY-appropriate, and saying otherwise would be misleading.
Issue | DIY? | Professional? | Why |
Start relay replacement | โ Yes | ย | $10โ40 part, no tools, fastest first step |
Condenser coil cleaning | โ Yes | ย | Vacuum and brush, takes 15 minutes |
Locked compressor replacement | No | โ Yes | Requires refrigerant recovery โ EPA-certified technicians handle recovery and recharge per Section 608 regulations |
Refrigerant leak diagnosis | No | โ Yes | Requires recovery equipment and EPA certification |
Control board replacement | Advanced DIY | โ Recommended | Part cost makes professional diagnosis worth it before committing |
Three levels summarize where Maytag compressor failure sits on the repair spectrum:
- Component level (start relay): DIY-doable, $10–40, solves the majority of clicking-won’t-start cases.
- Mechanical failure (locked compressor): Professional required — legally and practically.
- Environmental contributor (dirty condenser): Preventable with a $0 cleaning every 6–12 months.
The middle tier โ locked compressor โ is where the repair-or-replace question becomes relevant. For a unit under 7 years old with a compressor still within Maytag’s 10-year parts warranty, repair often makes economic sense. For a unit over 10โ12 years old with multiple aging components, replacement may be the better path. A technician who has assessed the unit can walk through that comparison without obligation.
Conclusion
Maytag compressor failure follows a clear decision tree. The sound it makes tells you where to start:
- Rhythmic clicking, 2–5 minutes apart, no hum → start relay. Shake test. Replace if it rattles.
- Short hum followed by a thud, compressor housing hot → locked compressor. Professional diagnosis.
- Compressor short-cycling, coils dirty → clean condenser first. Recheck over 24 hours.
- Compressor short-cycling, coils clean → sealed system pressure loss. Refrigerant-side diagnosis needed.
- Multiple erratic symptoms + display errors → control board possible, but start relay first.
Don’t let clicking run for days. The start relay failure that costs $15 to fix today can become a locked compressor that costs significantly more once the motor windings absorb repeated failed-start current surges.

FAQ
1. How urgent is a Maytag compressor clicking sound โ can I wait a few days?
Waiting carries real risk. Each failed startup attempt sends a full current surge through the compressor motor windings. Over repeated cycles โ which can number in the hundreds within 48 hours โ those surges degrade the winding insulation and can cause permanent electrical failure of the motor, turning what would have been a $15 start relay replacement into a full compressor job. If the clicking started recently and the unit is no longer cooling, address it within 24โ48 hours. Moving food to a cooler or secondary refrigerator is worth the effort to keep that window open.
2. Does Maytag's 10-year compressor warranty cover the labor cost?
Maytag’s 10-year limited warranty covers the compressor part only โ labor for diagnosis, refrigerant recovery, removal, installation, and recharge is not included. Coverage also requires that the unit was installed and maintained within Maytag’s documented guidelines. If the failure was linked to operation above the rated ambient temperature range, or condenser maintenance was neglected, coverage may be disputed. A technician who documents the failure mode and verifies the serial number against the purchase date creates the strongest foundation for a warranty claim if one applies.
3. Can dirty condenser coils actually cause Maytag compressor failure?
Over time, yes โ and it’s more direct than most owners realize. Condenser coils release refrigerant heat into the surrounding air after each compression cycle. When they’re coated with dust and debris, that heat stays in the system. The compressor runs longer and hotter on every cycle. Sustained elevated operating temperature degrades compressor oil viscosity, accelerates bearing wear, and breaks down motor insulation over months and years. In Atlanta โ where HVAC recirculation, pet dander, and red clay dust accumulate โ cleaning the condenser coils every six months is the most cost-effective thing an owner can do to protect compressor lifespan.
4. What does it mean when my Maytag compressor runs continuously without the unit cooling?
Continuous running without cooling is the sealed system failure pattern. The compressor motor is running, but it’s not moving refrigerant effectively โ either because refrigerant has leaked from the system or because internal compressor components have worn past the point of building usable pressure. This is distinct from a compressor that won’t start at all. Confirmation requires a technician with gauges to measure suction and discharge pressure at the sealed system service ports. Neither symptom nor sound alone is sufficient to diagnose this definitively.
5. Can a Maytag freezer compressor failure be confused with a defrost system failure?
Both produce a gradual temperature rise in a unit that appears to be running normally โ and they’re confused regularly. The diagnostic distinction is the manual defrost test: unplug the refrigerator for 24โ48 hours and let any frost on the evaporator coils fully thaw. Plug it back in. If the unit cools normally for 3โ5 days before the problem returns on the same timeline, the defrost system failed โ not the compressor. If the unit doesn’t cool at all even immediately after the manual defrost period, the sealed system is the issue. This one test separates the two without any instruments.
6. Is a Maytag compressor replacement worth it, or should I consider replacing the refrigerator?
A practical rule of thumb: if the repair cost approaches 50% of the replacement cost of a comparable refrigerator, replacement warrants serious consideration. However, if the unit is under 7 years old, the compressor is within Maytag’s 10-year warranty window (which reduces the part cost significantly), and the rest of the refrigerator is in good condition, a compressor repair typically extends the appliance’s service life by another 5โ10 years. A technician who has completed the diagnosis can give you the actual repair cost and a straightforward comparison โ without any obligation to choose either direction.
