Whirlpool Refrigerator ER2CHMXPQ04 Won't start or doesn't start

This start relay mounts on the side of the refrigerator's compressor and momentarily powers the start winding so the compressor can start reliably—helping restore consistent cooling and eliminating repeated click-and-no-start issues.

• Provides the initial boost to start the compressor, then disengages automatically
• Supports proper refrigerator and freezer temperatures by ensuring reliable compressor starts
• Common symptoms of a failing relay: warm temps, compressor won't start, rapid clicking or humming from the rear, or repeated overload trips
• Intermittent cooling after power cycling can also point to a weak start relay

• Unplug the refrigerator before servicing; pull the unit forward to access the rear
• The start device is under a small cover on the compressor side; remove the cover to access
• If a run capacitor is present, discharge it before handling any wiring
• Note wire positions and relay orientation; push the new relay straight onto the compressor pins without bending terminals, reinstall the cover, and restore power

This compressor overload is a thermal protector that opens the circuit if the compressor overheats or draws excessive current. Replacing a failed overload restores reliable starts and helps prevent compressor damage when your refrigerator won't cool.

• Protects the compressor by interrupting power during overheat/overcurrent conditions
• Common symptoms: refrigerator not cooling, compressor won't start, repeated clicking or brief hum then shutoff
• Mounts on the compressor terminal and works alongside the start relay on applicable models
• Built for proper fit and dependable operation in the start circuit

• Unplug the refrigerator and remove the rear access panel to reach the compressor
• Note wire positions; pull the old overload straight off the compressor pin
• Push the new overload fully onto the correct terminal and reconnect wiring/terminal cover
• Restore power and verify the compressor starts without repeated clicking
