OEM Carrier Furnace Control Transformer 40VA 120V–24V for Model PG9MAB060100ABSA

This OEM step-down transformer is the factory-specified replacement for the Carrier PG9MAB060100ABSA gas furnace, cross-referenced under OEM part number HT01BC116 (superseded by HT680054). The transformer converts 120V line voltage down to 24V AC to power the furnace's entire low-voltage control circuit — including the thermostat, gas valve, inducer relay, and ignition board. When this transformer fails, the result is a completely unresponsive furnace: no fan, no ignition attempt, no thermostat communication. If you're reading 0V AC between the R and C terminals on your control board, a failed transformer is the most common cause.

  • Specs: Primary Voltage: 120V AC | Secondary Voltage: 24V AC | VA Rating: 40VA | Frequency: 60 Hz | Phase: Single | Mounting: Foot-mount with wire leads
  • OEM vs Generic: This is a genuine OEM Carrier transformer built to exact factory VA tolerance. Generic transformers often run undersized VA ratings that cause nuisance tripping and premature failure — especially in systems with added accessories like humidifiers or UV air purifiers on the same 24V circuit.
  • Install difficulty: 2/5 — Cut power to the furnace at the breaker and verify 0V before touching any wiring. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph or label all wire connections before disconnecting the old transformer. Reconnect leads to the matching primary and secondary terminals and restore power to verify 24V output at R–C.
  • Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse when ordered before cutoff.

Compatibility: Direct OEM replacement for Carrier model PG9MAB060100ABSA gas furnace. Replaces original part number HT01BC116 and all related superseded numbers including HT01BC115, HT01BC120, HT01BB126, HT01CT120, and HT01AW115. Verify 120V primary and 40VA rating on your unit's data plate before ordering. Our team is available to confirm fitment — reach out before you buy.

Frequently Asked Questions

Does this Transformer fit my Carrier PG9MAB060100ABSA?
Yes. This is the factory-specified OEM transformer for the Carrier PG9MAB060100ABSA. 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 PG9MAB060100ABSA?
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?
