OEM Carrier 40VA Control Transformer HT01BC116 for Model PG8UAA048091ACJA

This OEM control transformer (part# HT01BC116) is the factory-specified replacement for the Carrier PG8UAA048091ACJA gas furnace. The transformer steps down 120V line voltage to 24V AC to power the entire low-voltage control circuit — including the thermostat, control board, gas valve, and ignition sequence. When this part fails, the furnace will appear completely unresponsive: no display, no call-for-heat reaction, and no ignition attempt whatsoever. A failed transformer is one of the most commonly misdiagnosed furnace faults, often mistaken for a bad control board.

  • Specs: Input 120V AC | Output 24V AC | 40VA rating | Factory-matched OEM design | Spade or wire-lead termination per factory configuration
  • OEM vs Generic: OEM transformers from Carrier are wound to exact VA tolerances, protecting downstream components like the gas valve and IFC board from voltage fluctuations. Generic alternatives may be under-rated, causing nuisance resets or premature board failure.
  • Install Difficulty: 2/5 — Disconnect power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to confirm 24V output post-install). Note wire polarity and lead positions before removing the old unit.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Engineered for the Carrier PG8UAA048091ACJA gas furnace. Always verify your existing transformer's input/output voltage and VA rating against your unit's data plate before ordering. Our HVAC parts specialists are available to confirm fitment — contact us before you order if you have any questions.

Frequently Asked Questions

Does this Transformer fit my Carrier PG8UAA048091ACJA?
Yes. This is the factory-specified OEM transformer for the Carrier PG8UAA048091ACJA. 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 PG8UAA048091ACJA?
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?
