OEM Carrier 120V–24V 40VA Control Transformer for Model PG8DAA060115ABJA (HT01BC116 / HT680054)

This is the OEM factory-specified control transformer for the Carrier PG8DAA060115ABJA gas furnace. The transformer steps household line voltage (120V AC) down to the 24V AC signal required to power the thermostat circuit, gas valve, inducer relay, and all low-voltage control components. When this transformer fails — due to a shorted low-voltage wire, a failed component, or simple age — the entire control circuit goes dead: the thermostat goes blank, the furnace refuses to start, and no heating cycle can initiate. Replacing this transformer restores full system operation.

  • Specs: Primary 120V AC | Secondary 24V AC | 40VA rating | Foot-mount configuration | Wire lead connections | 60 Hz
  • OEM vs Generic: This is a genuine OEM Carrier/Bryant transformer shipped in factory-authorized packaging. Generic aftermarket transformers are frequently mismatched in VA rating or mounting footprint — one customer noted a generic unit would not mount correctly without modification. OEM ensures a drop-in fit and proper VA headroom for all connected low-voltage loads.
  • Install difficulty: 2/5 — Shut off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, wire nuts or quick-connect terminals, multimeter (to verify 24V output after install). Label or photograph all wire connections before disconnecting. Install is typically 20–30 minutes.
  • Warranty & Shipping: 1-year OEM manufacturer warranty. In stock — ships same business day from our warehouse. Note: HT01BC116 has been superseded by OEM part HT680054; this listing ships the current OEM equivalent.

Compatibility: Designed for the Carrier PG8DAA060115ABJA gas furnace. This transformer also replaces legacy part numbers HT01BC116, HT01BC116B, HT01BC115, HT01BB126, HT01CT120, HT01BC120, HT01AW115, and HT01AA012. Always verify your existing transformer's input voltage, output voltage, and VA rating on the data plate before ordering. Our parts team is available to confirm fitment — just reach out before you buy.

Frequently Asked Questions

Does this Transformer fit my Carrier PG8DAA060115ABJA — HT01BC116?
Yes. This is the factory-specified OEM transformer for the Carrier PG8DAA060115ABJA — HT01BC116. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the transformer on my Carrier PG8DAA060115ABJA — HT01BC116?
Difficulty: Medium (30–45 min)
Step 1: Turn off breaker. Step 2: Photo wiring connections. Step 3: Disconnect wires from old transformer. Step 4: Remove mounting hardware. Step 5: Install new transformer, reconnect wires matching voltage ratings. Step 6: Verify 24V output with multimeter.
My thermostat has no power. What failed?
Thermostat with no display = failed 24V transformer (or blown control board fuse). Check the 3A/5A fuse on the control board first ($1–$5 fix). If fuse is good but no 24V output from transformer, replace transformer.
Is this transformer compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier transformer?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
How fast does National HVAC Parts ship?
