OEM Carrier Furnace Control Transformer 120V–24V 40VA for Model PG9MAA060120ACKA

This OEM control transformer is the factory-specified replacement for the Carrier PG9MAA060120ACKA gas furnace. The transformer steps down line voltage from 120V (primary) to 24V (secondary) at 40VA, powering the entire low-voltage control circuit — including the thermostat, gas valve, inducer relay, and control board. When this transformer fails, the furnace goes completely unresponsive: the thermostat goes dark, no ignition sequence initiates, and no error codes appear because there is no power to the control board at all.

Specs: Primary Voltage: 120 VAC | Secondary Voltage: 24 VAC | Rating: 40VA | Frequency: 50/60 Hz | Phase: Single | Factory-matched to OEM tolerance
OEM vs Generic: OEM transformers are wound to exact factory VA and voltage specs. Generic units often run outside rated VA, causing nuisance tripping, overheating, or premature control board failure from unstable 24V output.
Install Difficulty: 2/5 — Shut off power at the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output post-install). Photograph or label wire connections before removal. Replace the inline fuse if blown — a failed transformer sometimes takes the fuse with it.
Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PG9MAA060120ACKA gas furnace. Part number HT01BC116 has been superseded — this listing covers the current OEM-equivalent replacement. Always verify primary/secondary voltage and VA rating on your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy.

Frequently Asked Questions

Does this Transformer fit my Carrier PG9MAA060120ACKA?

Yes. This is the factory-specified OEM transformer for the Carrier PG9MAA060120ACKA. 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 PG9MAA060120ACKA?

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.
