Overview

This OEM 40VA control transformer (part 1011626) steps down 115V line voltage to the 24V control voltage that powers your ICP / Heil / Tempstar VNK100J16B2 furnace's control board, thermostat, gas valve, and relays. Rated at 40VA, it supplies enough power for the full low-voltage control circuit. When a transformer fails — usually from a shorted secondary, overload, or age — the entire control system goes dead: no thermostat display, no call for heat, and no response from the board. A buzzing, overheating, or scorched transformer is a clear sign of failure. This is a direct factory replacement that restores reliable 24V power.

Remove — Disconnect the leads, remove the mounting screws or nut, and lift out the failed transformer.
Install — Mount the new transformer, then reconnect the primary and secondary leads exactly per your photo.
Test — Restore power and confirm 24V at the secondary and a working thermostat call for heat.

Frequently Asked Questions

Does this Transformer fit my ICP VNK100J16B2 — 115V to 24V Control Transformer | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP VNK100J16B2 — 115V to 24V 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 VNK100J16B2 — 115V to 24V 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.
