Overview

This OEM control transformer (part number 1011626) supplies the low-voltage power for the Tempstar TNE100F14B1 gas furnace. It steps 115V line voltage down to 24V to power the control board, thermostat circuit, gas valve, and relays. Rated at 40VA, it delivers the capacity needed for the furnace's control loads. When a transformer fails — typically from a shorted secondary, a stuck relay, or a thermostat wiring fault — the furnace goes completely dead: no thermostat response, no blower, and no ignition sequence. A blown internal fuse link or a scorched, swollen housing clearly indicates failure.

How do I replace the transformer on my Tempstar TNE100F14B1 — 115V to 24V OEM 1011626 | 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 Tempstar 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 Tempstar 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.
