OEM Carrier Control Transformer 40VA for Model PG8DAA048095ADJA

This is the factory OEM replacement control transformer (part# HT01BC116) for the Carrier PG8DAA048095ADJA packaged gas furnace. The transformer steps down 120V line voltage to the 24V AC signal that powers your thermostat, control board, gas valve, and all low-voltage safety circuits. When it fails, the entire control circuit goes dark — no thermostat response, no ignition sequence, and nothing works. Replacing a failed transformer is one of the most impactful and cost-effective furnace repairs available.

• Specs: 40VA rating | 120V primary / 24V secondary | Factory-matched impedance and thermal protection | Direct OEM drop-in fit for Carrier part# HT01BC116
• OEM vs Generic: OEM transformers are wound to exact VA and voltage tolerances required by Carrier's IFC control board. Undersized or off-tolerance generic units can cause nuisance tripping, control board brownouts, and premature contactor coil failure.
• Install difficulty: 2/5 — Always shut off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output after install). Label all low-voltage wires before disconnecting the old transformer.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PG8DAA048095ADJA packaged gas unit. Verify your unit's data plate shows 120V/24V control voltage and cross-reference part number HT01BC116 before ordering. Our fitment team is available to confirm compatibility — just reach out before you buy.
