KitchenAid Compressor Clicking or Won't Start?
Fridge stopped humming, clicking every 5 minutes from the back, or the compressor feels extremely hot to the touch? We repair KitchenAid built-in and freestanding refrigerators — start relays, inverter boards, and full sealed-system compressor replacements. If we don't fix it, you don't pay.

While You Wait — 3 Steps for KitchenAid
Listen to the Back Panel
Pull the fridge out and listen. A single 'click,' then silence for 3–5 minutes, then another 'click' — that's the compressor trying and failing to start. Hear it once and unplug.
Unplug the Fridge
If the compressor is cycling (click–pause–click non-stop), disconnect power. Repeated failed start attempts overheat the motor windings and can turn a cheap relay fix into a full compressor replacement.
Keep the Doors Shut
Without the compressor running, the fridge holds temperature for about 8–12 hours with doors closed. Freezer holds longer than the fresh-food section.

A clicking KitchenAid compressor is not automatically a death sentence for the motor. In 70% of cases, when the fridge stops cooling and starts clicking, the culprit is a burned start relay or run capacitor — not the compressor itself.
Even on newer models with a linear inverter compressor, it's often the inverter control board that fails, while the compressor motor is completely fine. The board stops sending the start signal and the motor never runs.
I always measure the compressor winding resistance first — to verify the motor is still alive before ordering anything. If it's intact, swapping the relay or inverter board gets the fridge running the same day. No guesswork, no unnecessary parts.
Why Your KitchenAid Compressor Isn't Running — 4 Causes
We save compressors. Don't replace the fridge before calling us.
1. Start Relay / Run Capacitor (~50% of calls)
Clicking from the rear, compressor body is hot but not vibrating. The relay that triggers the motor has burned out. Inexpensive fix — and the most satisfying call to make: parts cost little, fridge is back by the same afternoon.
2. Condenser Fan Motor Failed (~20%)
The fan behind the lower rear panel seized or is clogged with dust and lint. Compressor overheats and cuts out on thermal overload protection. The compressor itself is usually fine — the fan is the fix.
3. Inverter Board Failed (~15%)
Found on newer KitchenAid linear compressor models (KRFC series). The inverter board on the compressor housing fails — usually from a voltage surge. Board replacement restores operation without touching the sealed system.
4. Locked Rotor — Compressor Seized (~15%)
The compressor motor has mechanically failed inside the sealed housing. Requires a full sealed-system repair: brazing the refrigerant lines, compressor swap, evacuation, and recharge. Major repair — but still worth it on built-in KitchenAid models.
