When a combined temperature/amperage value is above the limit specified by
the compressor manufacturer, a protector will operate independently,
turning off the compressor. The compressor will restart when this protector
has reset.
Note :
1. Compressor protector resets automatically.
2. If condenser fan is operating and the compressor is off, it is most likely that
the protector has operated.
