Overview

This OEM 24V control package for the ICP / Tempstar / Heil RGS303HREA0AAAA furnace covers the low-voltage transformer/relay circuit that switches the furnace's 24V loads. It includes the 24V DPDT relay (part 1183814, T92S11A22-24) and the 24V DPST relay (part 1178205, T92P7A22-24). These relays take the 24VA control signal from the transformer and switch line-voltage components such as the blower and inducer. When a coil burns open or the contacts pit and weld, the furnace may fail to start, the blower may run continuously, or you may hear chattering and buzzing from the control area. Replacing the 24V relay control restores clean, reliable switching of the furnace's heating and blower stages.

Frequently Asked Questions

Does this Transformer fit my ICP RGS303HREA0AAAA — 40VA Relay Kit | Ships Today?
Yes. This is the factory-specified OEM transformer for the ICP RGS303HREA0AAAA — 40VA Relay Kit | 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 RGS303HREA0AAAA — 40VA Relay Kit | 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.
