OEM Carrier Control Transformer 40VA 120V/24V for Model PG8JAA060155AAJA

This OEM control transformer (part# HT01BC116) is the factory-specified replacement for the Carrier PG8JAA060155AAJA gas furnace. The transformer steps line voltage down from 120V to 24V to power the low-voltage control circuit — including the thermostat, ignition board, gas valve, and all safety switches. When it fails, the entire control system goes dark: the thermostat gets no signal, the furnace won't respond to heat calls, and the system may blow the low-voltage fuse repeatedly.

• Specs: 120V primary | 24V secondary | 40VA rating | Bracket-mount design | Factory-matched OEM replacement for part# HT01BC116
• OEM vs Generic: This is a genuine OEM Carrier transformer with factory-matched VA rating and winding tolerance. Generic transformers often run at reduced VA capacity, causing voltage sag under load and premature control board failures.
• Install difficulty: 2/5 — Power down the unit at the disconnect and breaker before starting. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output post-install). Photograph all wiring connections before disconnecting the old transformer.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
