Overview

This OEM transformer assembly powers the 24V control circuit on the ICP/Heil/Tempstar WUGB130AG01 gas furnace. It steps 120V line voltage down to 24V at 40VA to feed the thermostat, gas valve, ignition control, and switching relays. The kit pairs the OEM transformer-relay receptacle (part 97298, TRANS RELAY RECEP 120>25 40VA) with a 24V SPDT relay (part 92840). A failed transformer cuts all low-voltage power — the thermostat goes blank, the gas valve cannot open, and the furnace won't start. Buzzing, overheating, or a repeatedly blown control fuse are classic symptoms of a failing 40VA transformer.

Frequently Asked Questions

Does this Transformer fit my ICP WUGB130AG01 — 120V to 24V with SPDT Relay | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP WUGB130AG01 — 120V to 24V with SPDT Relay | 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 WUGB130AG01 — 120V to 24V with SPDT Relay | 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.
