The transformer powers your system's entire 24V control circuit — including the thermostat, contactor coil, and control board. When it fails, nothing works: no call for heating or cooling will be answered, and the system will appear completely unresponsive. A blown transformer is often traceable to a short in the control wiring or a failed secondary component drawing excess current — always inspect the circuit before installing a replacement.
