OEM Carrier Control Transformer HT01BC116 for Model PG8DAA048115ACJA

This OEM control transformer (part number HT01BC116) is the factory-specified replacement for the Carrier PG8DAA048115ACJA gas furnace. The transformer steps down 120V line voltage to 24V AC, powering the low-voltage control circuit that operates your thermostat, gas valve, inducer relay, and integrated furnace control board. When this component fails, the entire control circuit goes dead — the furnace will not respond to thermostat calls, display any status codes, or attempt ignition.

• Specs: 120V primary | 24V secondary output | 40VA rating | Class 2 control circuit | Direct OEM replacement for part number HT01BC116
• OEM vs Generic: This is a genuine OEM Carrier transformer wound to exact factory VA and voltage tolerances. Generic transformers can run under-rated VA, causing voltage sag under load that leads to nuisance lockouts, erratic board behavior, and premature control board failure.
• Install Difficulty: 2/5 — Disconnect power at the breaker before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output after install). Label all low-voltage wires before disconnecting. Total job typically under 30 minutes for a qualified technician.
• Warranty: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct OEM fit for the Carrier PG8DAA048115ACJA gas furnace. Always verify primary voltage (120V) and VA rating on your existing transformer's label before ordering.
