OEM Carrier 40VA Control Transformer 120V–24V (HT01BC116) for Model PG8UAA060135ABJA

This OEM Carrier control transformer is the factory-specified replacement for the Carrier PG8UAA060135ABJA gas furnace. The transformer steps down 120V line voltage to the 24V signal voltage that powers your thermostat circuit, control board, gas valve, and every low-voltage safety control in the system. When this transformer fails — due to a shorted control wire, a failed component drawing excess current, or simple age — the entire furnace goes dead: no thermostat response, no ignition attempt, nothing. Replacing it is one of the most cost-effective furnace repairs available.

  • Specs: 40VA rating | 120V primary / 24V secondary | 50/60 Hz | Single phase | Compact 3" × 2" × 2" housing | Wire-lead connections
  • OEM vs Generic: This OEM unit is wound to exact Carrier factory tolerances, ensuring the full 40VA capacity under load. Undersized or off-tolerance generic transformers can overheat, trip their internal thermal fuse, or fail prematurely — especially if a minor wiring fault exists downstream.
  • Install difficulty: 2/5 — Always shut off power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, wire stripper, multimeter (to confirm 24V output after install). Photograph or label all wire connections before disconnecting. Note: if a transformer fails repeatedly, inspect low-voltage wiring for shorts before installing the new unit.
  • Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day when ordered by 5 PM local time.

Compatibility: Direct OEM replacement for Carrier model PG8UAA060135ABJA gas furnace. OEM part number HT01BC116 has been superseded by HT680054 — both are fulfilled as the current production unit. Also compatible with Bryant and Payne furnaces sharing the same transformer specification. Always verify primary voltage (120V) and VA rating (40VA) on your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy — ships today.

Frequently Asked Questions

Does this Transformer fit my Carrier PG8UAA060135ABJA?
Yes. This is the factory-specified OEM transformer for the Carrier PG8UAA060135ABJA. 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 Carrier PG8UAA060135ABJA?
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 Carrier 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 Carrier 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?
