Thermal Limiting Fuse: Testing and Inspection

1. Unplug Thermal Limiter wiring connector.
2. With an ohmmeter check for continuity between the two terminals. If no continuity is present, replace the compressor.
3. The Thermal Limiter is calibrated to open and close at:
- Open circuit (no continuity) at 122 to 128 °C (252 to 262 °F)
- Close circuit (continuity) at 106 to 116 °C (225 to 235 °F)

There is no serviceability of the thermal limiter switch. If the thermal limiter switch fails, the compressor must be replaced.
