OEM Carrier 40VA Control Transformer HT01BC116 for Model PG8UAA036065ACJA

This is the factory OEM replacement control transformer for the Carrier PG8UAA036065ACJA gas furnace. The transformer steps down 120V line voltage to 24V AC to power the furnace's control board, thermostat circuit, and all low-voltage safety controls. When this component fails, the entire control circuit goes dead — no thermostat display, no ignition attempt, no fan response, and no error codes on the board. Replacing the transformer is often the fastest and most cost-effective fix before condemning an otherwise functional control board.

• Specs: 40VA rating | 120V primary / 24V secondary | Direct OEM replacement | Part Number HT01BC116 | Factory-matched terminals for plug-and-play installation
• OEM vs Generic: OEM transformers are wound and insulated to Carrier's exact specifications, ensuring stable 24V output under load. Generic units may deliver fluctuating voltage that causes nuisance lockouts or premature control board failure.
• Install difficulty: 2/5 — Shut off power at the breaker and verify zero voltage before starting. Tools needed: flathead and Phillips screwdrivers, multimeter (to confirm 24V output after install), wire stripper. Label all low-voltage wires before disconnecting for a clean reinstall.
