Thermal Limiting Fuse: Description and Operation
The thermal limiter switch is used to measure the compressor surface temperature. If the compressor surface temperature is excessive, the switch will cut
the battery feed voltage to the compressor clutch coil. The switch will reset itself, once the compressor surface temperature returns to normal.
The thermal limiter switch will interrupt the battery feed to the compressor clutch coil at a temperature of about 122 - 128 °C (250 - 260 °F). The switch
will reset and restore the clutch coil operation at a temperature of about 104 - 116 °C (220 - 240 °F). The thermal limiter switch cannot be repaired, and
is not available as a serviceable item. If faulty or damaged, the entire compressor must be replaced.
