Overview

This genuine OEM 40VA control transformer (part number 1011626) steps the 115V line voltage down to the 24V control voltage that powers the Tempstar TCK075F14A1's thermostat, gas valve, relays, and control board. Rated at 40VA, it supplies the low-voltage circuit that runs the entire ignition and safety sequence. A burned-out or shorted transformer kills all 24V control power — the furnace goes completely dead, the thermostat screen blanks, and no sequence will start. Replacing it restores the control circuit to spec.

My thermostat has no power. What failed?
