Kitchenaid Refrigerator KBLC36MHS01 Won't start or doesn't start

This compressor overload is the thermal protector for your refrigerator's compressor. It opens the circuit when the motor overheats or draws excessive current, helping prevent damage and restoring reliable starts when the original protector fails.

• Interrupts power to protect the compressor during overheat or overcurrent conditions
• If failed, symptoms include: compressor won't start, repeated clicking or brief hum then stop, warm refrigerator/freezer, and an unusually hot compressor shell
• A weak protector may trip repeatedly and reset after cooling, causing intermittent cooling
• Works in tandem with the start relay/device to manage compressor startup current

• Disconnect power before servicing and pull the unit forward for rear access
• Remove the rear cover; note wire positions and take a photo for reference
• Pull the old overload straight off the compressor terminal; transfer leads and firmly seat the new overload in the same orientation
• Capacitors can retain a charge—handle with care; reinstall cover and restore power to test

This PTC start relay mounts on the compressor and momentarily powers the start winding to get the motor running, then disengages for normal operation. Replacing a weak relay can stop repeated clicking and help restore cooling.

• Provides initial boost to the compressor's start winding for reliable startup
• Automatically drops out after startup so the compressor runs on the run winding
• Helps address symptoms like warm temperatures, compressor clicking or humming without starting, or frequent overload trips
• Failure may show as rattling, burn marks, or a melted relay housing

• Disconnect power and remove the rear access panel to reach the compressor
• Allow components to cool; note wire locations and take a reference photo
• Pull the old relay straight off the compressor pins; align and firmly seat the new relay in the same orientation, then reconnect wires
• If your unit uses a run capacitor and/or separate overload protector, reconnect per the wiring diagram before restoring power

This Power Disconnect Switch is the refrigerator's on/off service switch. It interrupts incoming power when actuated, allowing safe servicing or resetting of the unit without unplugging it and helping prevent unintended operation when access panels are open. What it does:

• Interrupts electrical power to the unit when switched off or tripped
• Provides a dedicated service disconnect for safe maintenance and resets
• Common symptoms: no power, intermittent shutdowns, or the unit won't stay on unless the switch is held/positioned
• Visual clues: broken actuator or heat-discolored/loose terminals

• Power disconnect switch only

• Disconnect power at the breaker before servicing
• Access the switch location; on many built-in units it's behind the top grille or control panel
• Move wires one at a time to the new switch to maintain correct orientation
• Restore power and verify the switch cleanly turns the unit on and off
