This genuine Comfortmaker OEM definite-purpose contactor (Part #85066) is a 2-pole, 20-amp unit with a 24-volt control coil. It is the electromagnetic switch that closes the high-voltage circuit to the compressor and condenser fan whenever the thermostat sends a 24V signal. Contactors fail from arc-pitted contacts, a chattering or burned-out coil, or stuck points caused by ant infestation and surface burning. Symptoms include the outdoor unit not starting, a loud hum or buzz without the compressor running, contacts welded closed so the unit won't shut off, or visible pitting and melting on the contact pads. This OEM contactor restores clean, reliable switching for the compressor circuit.
