OEM Carrier Transformer 40VA 120V/24V for Model PG8DAA036095ADJA

This OEM replacement transformer (part number HT01BC116) is the factory-specified control circuit transformer for the Carrier PG8DAA036095ADJA packaged gas unit. The transformer steps down 120V line voltage to the 24V AC signal used by the thermostat, control board, gas valve, and all low-voltage system controls. When this component fails, the entire control circuit goes dead — the thermostat receives no power, relays won't energize, and the unit will not respond to any call for heating or cooling.

• Specs: 40VA rating | 120V primary / 24V secondary | Ring-type or foot-mount bracket | Factory-matched impedance for stable low-voltage output
• OEM vs Generic: This is a genuine OEM Carrier transformer sourced directly from the factory. OEM units are wound to exact VA and impedance specifications, preventing nuisance tripped fuses and protecting sensitive control boards. Generic aftermarket transformers often run near or at VA limits, causing voltage sag under load and premature failures.
• Install Difficulty: 2/5 — Disconnect all power before servicing. Tools needed: flathead and Phillips screwdrivers, multimeter, wire nuts or terminal connectors. Confirm secondary voltage output (should read 24–28V AC) before reconnecting load wiring. Always photograph terminal wiring before disconnecting.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse.

Compatibility: Specifically fits the Carrier PG8DAA036095ADJA 3-ton, 95,000 BTU packaged gas unit. Always verify your existing transformer's VA rating and voltage markings on the data plate before ordering. Not sure it fits?
