Component Replacement

In addition to checking and adjusting the compressor oil level (see Compressor Oil Check), certain component replacement requires additional refrigeration oil. Add specified amounts of oil directly to the component prior to installation.

THERMAL LIMITER

NOTE: On vehicles equipped with a Low Refrigerant Charge Protection System (Superheat Switch and Thermal Limiter), if compressor operation is required before full system refrigerant charge is obtained, disconnect the thermal limiter and connect a jumper wire between terminals "B" and "C" of the limiter. When system adjustments and repairs are complete, and full system charge is obtained, reconnect thermal limiter to its original condition. This is required in orders to prevent thermal limiter from sensing the low refrigerant and stopping system operation.
