Overview

This OEM 40VA control transformer (part #97298) steps the WUGD175CK01's 120V line voltage down to 24V to power the thermostat circuit, gas valve, and relays. The kit also includes the OEM 24V SPDT relay (part #92840) used in this model's control sequence. A failed transformer kills the entire low-voltage control system — the furnace stops responding to the thermostat, the blower won't run on a call for heat, and ignition never starts. Buzzing, overheating, or a repeatedly blown control fuse all point to transformer failure.

Frequently Asked Questions

Does this Transformer fit my ICP WUGD175CK01 — 120V to 24V | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP WUGD175CK01 — 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 WUGD175CK01 — 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.
