OEM Carrier 24V Control Circuit Transformer HT01BC116 for Model PG8DAA024070ABJA

This is the factory OEM replacement transformer for the Carrier PG8DAA024070ABJA packaged gas furnace unit. The transformer steps down line voltage (120V) to the 24V signal required by the control board, thermostat, and zone controls. When this component fails, the entire low-voltage control circuit goes dead — symptoms include a completely unresponsive thermostat, no call-for-heat response, and all control board indicator lights going dark. Replacing the transformer with the correct OEM part (HT01BC116) restores factory-spec voltage regulation and protects downstream components from over- or under-voltage damage.

• Specs: OEM Part# HT01BC116 | 120V primary → 24V secondary step-down | 40VA rated output | Factory-matched for Carrier PG8DAA024070ABJA control circuit requirements
• OEM vs Generic: OEM transformers are wound and tested to exact Carrier voltage and VA specifications. Generic alternatives often carry wider output tolerances that can stress the control board, flame sensor circuit, and gas valve solenoid — leading to premature component failure.
• Install Difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to confirm 0V before touching wiring). Label or photograph all low-voltage wire connections before removal. Typical swap takes 20–30 minutes.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse — order by 3 PM local time to go out today.
