OEM Carrier Furnace Control Transformer 40VA 120V/24V for Model PG8DAA060135ACJA

This OEM control transformer is the factory-specified replacement for the Carrier PG8DAA060135ACJA gas furnace. The transformer steps down 120V line voltage to the 24V control circuit voltage that powers your thermostat, gas valve, contactor, and all low-voltage control functions. When this transformer fails, the entire control circuit goes dead — the thermostat goes blank, the furnace won't respond to any call for heat or cooling, and no diagnostic error codes can even be generated. This is one of the first components to inspect when the system appears completely unresponsive.

  • Specs: 40VA rating | 120V primary voltage | 24V secondary voltage | Step-down design | Wire lead connections | Direct OEM replacement for HT01BC116 (superseded by HT680054)
  • OEM vs Generic: OEM transformers are wound to exact VA and voltage tolerances required by the Carrier control board. Undersized or off-tolerance generic transformers can cause nuisance lockouts, damage sensitive control boards, or fail prematurely under full load.
  • Install Difficulty: 2/5 — Shut off power at the breaker and verify zero voltage with a multimeter before touching any wiring. Tools needed: flathead and Phillips screwdriver, multimeter, wire stripper. Label all wire connections before removal and confirm polarity when reconnecting.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG8DAA060135ACJA gas furnace. This transformer also crosses to Bryant and Payne models sharing the HT01BC116 specification. Always verify the 40VA / 120V–24V rating on your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork required.
