OEM Carrier Furnace Transformer 120V–24V 40VA for Model PG9MAA024060AEKA

This OEM step-down transformer (part number HT01BC116, superseded by HT680054) is the factory-specified control-circuit transformer for the Carrier PG9MAA024060AEKA gas furnace. Its job is to convert 120V line voltage down to 24V AC to power the thermostat, control board, gas valve, and every other low-voltage component in the system. When it fails, the entire control circuit goes dark — the thermostat shows no response, the furnace will not attempt ignition, and you may measure 0V between the R and C terminals on the control board.

  • Specs: Primary voltage: 120V AC | Secondary voltage: 24V AC | VA rating: 40VA | Frequency: 60Hz | Connection type: wire leads with foot-mount bracket | Includes 3A fuse protection
  • OEM vs Generic: This is a factory-authorized OEM replacement, meeting exact VA rating and mounting tolerances for the PG9MAA024060AEKA. Generic transformers often carry loose VA tolerances and non-matching mount footprints, requiring modification and risking under-powered low-voltage circuits.
  • Install difficulty: 2/5 — Shut off power at the breaker and verify 0V before touching any wiring. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wire connections before disconnecting. Check R-to-C voltage after install to confirm 24V output.
  • Warranty & Shipping: Backed by a 1-year OEM warranty. In stock and ships same business day from our warehouse.

Compatibility: Fits Carrier model PG9MAA024060AEKA gas furnace. Note: OEM part number HT01BC116 has been superseded by HT680054 — both are the correct factory replacement for this model. Also crosses to Bryant and Payne units sharing the same transformer specification. Verify 120V primary / 24V secondary / 40VA rating on your unit's data plate before ordering.

How do I replace the transformer on my Carrier OEM Carrier Furnace Transformer 120V-24V 40VA — PG9MAA024060AEKA?

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.
