ICP Transformer 40VA 120/24V for WFEL110C060A1 — Genuine OEM | Ships Today

Overview

This genuine OEM 40VA control transformer (part number 1177217) supplies the low-voltage power that runs the entire control circuit of your ICP Tempstar Heil WFEL110C060A1 furnace. It steps the 120-volt line voltage down to the 24-volt signal that operates the thermostat, gas valve, control board, relays, and safety switches. Without a working transformer, none of the furnace's controls receive power — the unit appears completely dead even though line voltage is present. A failed transformer typically results from a shorted secondary circuit, a stuck contactor, or simple age-related winding breakdown, and it is one of the most common no-heat service calls.

Specifications

Compatibility

Engineered as a direct factory replacement for the ICP Tempstar Heil WFEL110C060A1 gas furnace. The 1177217 transformer is also used across many comparable ICP-family (Comfortmaker, Arcoaire, KeepRite) furnace platforms that share the same 120V control architecture. Always confirm your existing transformer is rated 40VA, 120V primary / 24V secondary before installing.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter before touching any wiring.
2. Access — Remove the furnace blower-compartment service panel to reach the control area.
3. Document — Photograph all primary and secondary wire connections before disconnecting anything.
4. Remove — Disconnect the 120V primary leads and 24V secondary leads, then unbolt the failed transformer from the control bracket or panel.
5. Install — Mount the new 1177217 transformer, reconnect the primary and secondary leads exactly per your photo, and confirm tight terminals.
6. Test — Restore power and verify 24V across the secondary and a normal thermostat call.

Signs You Need a Replacement

• Furnace control board, display, and thermostat are completely dead with line voltage present
• No 24V reading across the transformer secondary terminals
• Blown low-voltage fuse that re-blows immediately
• Burnt smell or visibly scorched transformer windings
