Multi-Function Thermal Sensor / Switch: Testing and Inspection
THERMAL LIMITER SWITCH1. Unplug Thermal Limiter connector.
2. With an ohmmeter, check for continuity between the two terminals. If no continuity is present replace compressor.
3. The Thermal Limiter is calibrated to open and close at:
- Open circuit (no continuity) Temperature: 122 -128° C (252 - 262° F)
- Close circuit (continuity) Temperature: 106 -116° C (225 - 235° F)
NOTE: The thermal limiter switch is not serviceable. If the switch fails, the compressor must be replaced.
