Overview

This OEM control transformer (part #1177217) steps the incoming 120-volt line voltage down to the 24-volt control voltage that powers the thermostat, gas valve, control board, and relays in your ICP/Heil/Tempstar WFSR060A042A1 furnace. Rated at 40VA, it supplies the low-voltage circuit that every modern furnace depends on. A failed transformer leaves the entire control system dead — no thermostat display, no ignition, no call for heat — and is a frequent cause of a completely unresponsive furnace.

Frequently Asked Questions

Does this Transformer fit my ICP WFSR060A042A1 — 120V to 24V | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP WFSR060A042A1 — 120V to 24V | Ships Today. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.

How do I replace the transformer on my ICP WFSR060A042A1 — 120V to 24V | Ships Today?

Difficulty: Medium (30–45 min)
Step 1: Turn off breaker. Step 2: Photo wiring connections. Step 3: Disconnect wires from old transformer. Step 4: Remove mounting hardware. Step 5: Install new transformer, reconnect wires matching voltage ratings. Step 6: Verify 24V output with multimeter.

My thermostat has no power. What failed?

Thermostat with no display = failed 24V transformer (or blown control board fuse). Check the 3A/5A fuse on the control board first ($1–$5 fix). If fuse is good but no 24V output from transformer, replace transformer.

Is this transformer compatible with Bryant or Payne too?

Many ICP parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my ICP transformer?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
