OEM Carrier Transformer 120V–24V 40VA for Model PG9MAB060140ABSA

This is the factory-specified OEM replacement transformer (part number HT01BC116) for the Carrier PG9MAB060140ABSA gas furnace. The transformer steps down 120V line voltage to the 24V signal voltage required to power the control board, thermostat circuit, and all low-voltage safety controls. When this transformer fails, the entire control circuit goes dark — the thermostat shows no response, the board has no power, and the furnace will not attempt a heat cycle at all. It is one of the first components to inspect when a furnace is completely unresponsive.

  • Specs: Input: 120V AC | Output: 24V AC | VA Rating: 40VA | OEM Part Number: HT01BC116 | Factory-matched windings and mounting footprint
  • OEM vs Generic: This OEM unit meets Carrier's exact VA rating and insulation class. Undersized or off-brand transformers can overheat under control-board load, causing nuisance tripping or premature failure of downstream components.
  • Install Difficulty: 2/5 — Disconnect power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter. Label or photograph all wiring connections before removal. Typical swap time is 15–30 minutes for an experienced technician.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct OEM replacement for the Carrier PG9MAB060140ABSA gas furnace. Always verify your existing transformer's input/output voltage and VA rating against your unit's data plate before ordering. Our team is available to confirm fitment — order with confidence and get your system back online today.

Frequently Asked Questions

Does this Transformer fit my Carrier PG9MAB060140ABSA?
Yes. This is the factory-specified OEM transformer for the Carrier PG9MAB060140ABSA. 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 PG9MAB060140ABSA?
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.
