Overview
This OEM control transformer is a direct replacement for the 24-volt power supply in your ICP Tempstar/Heil WFAR080C060B2 furnace. OEM part 1177217 is a 40VA step-down transformer with a 120V primary and a 24V secondary. It converts incoming line voltage into the low-voltage control power that drives the thermostat, control board, gas valve, and relays. When a transformer fails — often from a shorted secondary or a power surge — the entire low-voltage control circuit goes dead: the thermostat screen blanks, the furnace won't respond to a heat call, and no 24V is present at the R-C terminals. A 40VA rating provides ample headroom for the furnace's control load.

Compatibility
Engineered as a direct-fit replacement for the ICP Tempstar Heil WFAR080C060B2 furnace control circuit. This 120-24V, 40VA transformer is common across many ICP-family furnaces sold under the Tempstar, Heil, Comfortmaker, and Arcoaire names. Verify your primary is 120V (not 208/240V) before ordering.
Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker. Verify zero voltage with a multimeter.
- Access — Remove the control-compartment service panel.
- Document — Photograph the primary (line) and secondary (24V) wire connections before disconnecting.
- Remove — Disconnect the leads, remove the mounting screw or nut, and lift out the failed transformer.
- Install — Mount the new transformer, then reconnect the 120V primary and 24V secondary leads exactly per your photo.
- Test — Restore power and confirm 24V across the secondary, then run a heat cycle to verify controls respond.
Signs You Need a Replacement
- Thermostat is blank or unresponsive with no 24V present
- Furnace does not start on a call for heat
