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
