Overview

This genuine OEM control transformer (part number 1012722, TRANS 115>24 40VA) steps the furnace's 115V line voltage down to the 24V low-voltage power that drives the thermostat, gas valve, control board, and ignition circuits on the ICP / Tempstar / Heil VNE050B12G1. Rated at 40VA, it provides ample current for the complete furnace control circuit. A failed transformer is a leading cause of a totally dead furnace — without 24V there is no thermostat response, no call for heat, and no blower. The correct OEM transformer restores full low-voltage control power and normal operation.

Compatibility

Direct OEM replacement for the ICP VNE050B12G1 furnace. This 40VA 115-to-24V transformer also fits many ICP-family furnaces marketed under Tempstar, Heil, and Comfortmaker that originally used part 1012722. Verify the VA rating and primary/secondary voltages against your existing transformer before installing.

Installation Guide

  1. Safety First — Disconnect electrical power at the furnace switch and breaker. Verify zero voltage at the transformer terminals with a multimeter.
  2. Access — Remove the furnace control/blower panel to reach the transformer, usually mounted near the control board or junction box.
  3. Document — Photograph all primary (line) and secondary (24V) wire connections before disconnecting.
  4. Remove — Disconnect the leads, remove the mounting screws or bracket, and take out the failed transformer.
  5. Install — Mount the new transformer and reconnect the 115V primary and 24V secondary wiring exactly per your photo.
  6. Test — Restore power and confirm 24V at the secondary, a responsive thermostat, and a normal heat cycle.

Signs You Need a Replacement

  • Completely dead furnace — no thermostat display or no response to a call for heat
  • No measurable 24V at the transformer secondary or control board R/C terminals
  • Blown low-voltage fuse on the control board, or a burnt transformer smell
  • Intermittent control failures following a short or wiring fault

Frequently Asked Questions

Does this Transformer fit my ICP VNE050B12G1 — 115V to 24V Furnace Control Transformer | Ships Today?
Yes. This is the factory-specified OEM transformer for the ICP VNE050B12G1 — 115V to 24V Furnace Control Transformer | 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 VNE050B12G1 — 115V to 24V Furnace Control Transformer | 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.
How fast does National HVAC Parts ship?
