OEM Carrier Control Transformer 40VA 120V/24V for Model PG8DAA036095ABJA

This is the factory OEM replacement control transformer (part number HT01BC116) for the Carrier PG8DAA036095ABJA gas furnace. The transformer steps down 120V line voltage to the 24V AC signal that powers your thermostat, gas valve, inducer relay, and all low-voltage control circuitry. When this transformer fails, the entire control circuit loses power — resulting in a completely unresponsive thermostat, no ignition sequence, and a furnace that won't start at any time of year.

• Specs: 40VA capacity | Primary: 120V AC | Secondary: 24V AC | Factory-matched OEM winding and mounting footprint for direct drop-in replacement
• OEM vs Generic: OEM transformers like HT01BC116 are wound to exact VA and voltage tolerances required by Carrier's IFC (Integrated Furnace Control) board. Undersized or off-tolerance generic units can cause nuisance tripping, board damage, or intermittent thermostat faults.
• Install difficulty: 2/5 — Shut off power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to confirm 24V output post-install). Photograph existing wiring connections before disconnecting leads.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed specifically for the Carrier PG8DAA036095ABJA packaged gas furnace. Always verify your existing transformer's VA rating and primary/secondary voltages on the data plate or wiring diagram before ordering.
