The transformer converts 120V line voltage down to 24V AC to power all low-voltage control-circuit components — including the thermostat, control board, gas valve solenoid, and inducer relay. When this transformer fails, the entire control circuit loses power: the thermostat goes dead, the furnace will not respond to any call for heat, and nothing operates — even though line voltage is present at the unit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary (input) | 24V secondary (output) | 60 Hz | Single phase | Foot-mount configuration | Wire lead connections with insulated female quick-connect terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier replacement, factory-matched to the exact VA rating and output voltage tolerance required by the PG8UAA060135AAJA control board. Generic transformers frequently run outside tolerance, risking nuisance tripping, control board damage, or premature gas valve failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Shut off all power to the furnace at the breaker and disconnect switch before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to confirm 24V output after install). Photograph all wire connections before disconnecting the old transformer. Always check for a blown 3A inline fuse on the secondary circuit before condemning the transformer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty.

This part also cross-references to multiple Carrier, Bryant, and Payne furnace models sharing the same 40VA 120V\/24V transformer specification — verify your unit's data plate before ordering. Note: OEM part number HT01BC116 has been superseded by HT680054; both are the same factory-spec transformer.
