Maytag Overload (Thermal Protector)

5.0 (1)

By: Whirlpool

Part Number: WP4344040

This overload is a thermal protection device that mounts on the motor/compressor and opens the circuit when excessive heat or current is detected. Replacing a weak or failed overload helps restore safe startup and protects the windings from damage. What it does:

Monitors motor/compressor temperature and current draw
Interrupts power on overheat/overload to prevent damage
Aids troubleshooting of start/run issues when paired with the start device
Common symptoms: hums then clicks off, won't start, intermittent shutdown, frequent tripping

What's included:

1 thermal overload protector

Install notes:

Disconnect power before servicing; allow components to cool
Access the terminal area on the motor/compressor; remove any cover
Note/photograph wire positions; transfer wires and fully seat the new overload on the correct terminal
Inspect the start relay, capacitor, and terminals for heat damage; replace any compromised parts
