OEM Carrier Furnace Transformer 40VA 120V–24V for Model PG8JAA060090ACJA

This OEM step-down transformer is the factory-specified replacement for the Carrier PG8JAA060090ACJA gas furnace. The transformer converts 120V line voltage down to 24V AC to power all low-voltage control circuit components — including the thermostat, control board, gas valve, and inducer relay. When this transformer fails, the entire control circuit goes dark: the thermostat shows no response, the furnace refuses to start, or the system intermittently loses power mid-cycle. Note: OEM part number HT01BC116 has been superseded by HT680054, the current factory-authorized direct replacement shipped in a Carrier factory-authorized parts box.

  • Specs: 40VA rating | 120V primary input | 24V secondary output | 60 Hz | Single phase | Foot-mount configuration | Wire lead connections
  • OEM vs Generic: OEM transformers are wound to exact VA and voltage tolerances. Undersized or off-tolerance generic units can overdraw current, trip the furnace's low-voltage fuse, and damage the control board — turning a $50 repair into a $200 one.
  • Install difficulty: 2/5 — Shut off power at the breaker and confirm zero voltage before disconnecting leads. Photograph all wiring connections before removal. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (verify 24V output after install). Always check for a blown low-voltage fuse before condemning the transformer.
  • Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PG8JAA060090ACJA gas furnace. Also replaces legacy part numbers HT01BC116, HT01BC115, HT01BB126, HT01CT120, HT01BC120, and additional Carrier/Bryant/Payne variants — verify primary voltage (120V) and VA rating (40VA) on your unit's data plate before ordering.

Frequently Asked Questions

Does this Transformer fit my Carrier PG8JAA060090ACJA?
Yes. This is the factory-specified OEM transformer for the Carrier PG8JAA060090ACJA. 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 PG8JAA060090ACJA?
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?
Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
