OEM Carrier Furnace Control Transformer 40VA 120V/24V for Model PG8DAA060135ABJA

This OEM control transformer is the factory-specified replacement for the Carrier PG8DAA060135ABJA gas furnace, replacing original part number HT01BC116 (superseded by HT680054). The transformer steps down 120V line voltage to the 24V signal required to power the control board, thermostat circuit, gas valve, and all low-voltage controls. When it fails, absolutely nothing works — the furnace will not respond to the thermostat, the inducer won't start, and no error codes will display because the control board itself has no power.

  • Specs: 40VA rating | Primary: 120V AC | Secondary: 24V AC | Step-down type | Wire lead connections | Replaces OEM part HT01BC116 / HT680054
  • OEM vs Generic: OEM transformers are wound to exact VA and voltage tolerances specified by Carrier's engineers. Undersized or off-tolerance generic units can cause nuisance board lockouts, erratic thermostat behavior, and premature failure of the control board due to voltage sag under load.
  • Install difficulty: 2/5 — Shut off power at the breaker before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output after install). Label all wire connections before removal and photograph wiring harness orientation.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Fits Carrier model PG8DAA060135ABJA gas furnace. This part is also used across the Carrier, Bryant, and Payne furnace family — verify your unit's data plate shows a 120V primary / 24V secondary transformer before ordering. Our fitment team is available to confirm compatibility prior to purchase.
