Fig. Fig. 1: View of a thermal limiter fuse

The thermal fuse consists of a temperature sensitive fuse link and a wire wound resistor enclosed in a plastic housing. There are three spade-type electrical terminals which plug into an in-line connection at the wiring harness to the air conditioning compressor.

A blown thermal fuse indicates that the air conditioning system is either low or completely out of refrigerant charge, a malfunctioning POA or expansion valve or an improperly located thermal limiter.
