When the 24V coil energizes on a call for cooling, the contactor pulls in and passes line voltage to the outdoor unit; its built-in shunt provides reliable switching for the WJA436000KTP0A1 system. A failed contactor shows up as a buzzing or chattering outdoor unit, pitted or welded contacts that won't break the circuit, or an outdoor unit that won't start at all.
