OEM Carrier 40VA Control Transformer HT01BC116 for Model PG8JAA066135ACJA

This OEM control transformer is the factory-specified replacement for the Carrier PG8JAA066135ACJA packaged gas furnace. The transformer steps down 120V line voltage to 24V AC to power the control board, thermostat circuit, and all low-voltage safety controls. When it fails, the entire control circuit goes dead — the thermostat goes blank, the system won't respond to any call for heat or cooling, and nothing operates. A shorted transformer will often trip the low-voltage fuse on the control board as well.

  • Specs: 120V primary | 24V secondary | 40VA rating | Factory-matched OEM replacement for Part# HT01BC116
  • OEM vs Generic: This is the exact factory transformer sourced from Carrier. OEM units are wound to precise VA and voltage tolerances, preventing control board brownouts and nuisance lockouts that undersized generic transformers commonly cause.
  • Install difficulty: 2/5 — Disconnect all power before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to confirm 24V output after install). Always label or photograph wire connections before removal.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed specifically for the Carrier PG8JAA066135ACJA packaged gas furnace. Verify part number HT01BC116 on your existing transformer label before ordering. Our fitment team is available to confirm compatibility — just reach out before you buy. Order today for same-day shipping.

Frequently Asked Questions

Does this Transformer fit my Carrier PG8JAA066135ACJA?
Yes. This is the factory-specified OEM transformer for the Carrier PG8JAA066135ACJA. 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 PG8JAA066135ACJA?
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.
