Defrost Drain Heater
The defrost drain heater is a 4-inch long resistive
heater that is inserted into the drain opening. The
heater is not attached and easily pulls out of the
drain. The wiring is routed on the right side of the
evaporator and connects above the evaporator into
a single connector. It is necessary to remove the
evaporator cover to access the defrost drain heater.
