OEM Carrier 40VA Control Transformer HT01BC116 for Model PG9MAA060080AAKA

This OEM control transformer is the factory-specified replacement for the Carrier PG9MAA060080AAKA gas furnace. The transformer steps down 120V line voltage to the 24V signal used by the thermostat, control board, gas valve, and all low-voltage control circuits. When it fails, the entire control circuit goes dark — the thermostat display may go blank, the furnace will not respond to any call for heat or cooling, and a blown fuse is often the first clue. Replacing with the correct OEM unit ensures exact voltage output and VA capacity to protect downstream components.

• Specs: Input 120VAC | Output 24VAC | 40VA rating | OEM part number HT01BC116 | Factory-matched for Carrier PG9MAA060080AAKA
• OEM vs Generic: This OEM transformer is wound to Carrier's exact 40VA specification, protecting sensitive control boards from voltage fluctuation. Off-brand units with loose VA tolerance can cause nuisance lockouts or premature board failure.
• Install Difficulty: 2/5 — Shut off power at the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, multimeter, wire nuts or quick-connects. Confirm 24V output across secondary terminals after installation before restoring full power.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
