Thermal Limiter Switch: Operation
WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
The thermal limiter switch interrupts battery feed to the A/C clutch field coil when temperatures reach above 122 - 128° C (250 - 260° F). The switch restores clutch field coil battery feed when the temperature drops to below 104 - 116° C (220 - 240° F).
The thermal limiter switch cannot be adjusted or repaired and , if faulty or damaged, the A/C compressor must be replaced
