OEM Carrier Furnace Transformer 40VA 120V-24V for Model PG9MAA060140AEKA

This OEM step-down transformer is the factory-specified replacement for the Carrier PG9MAA060140AEKA gas furnace. Originally sold under part number HT01BC116 and updated by Carrier to the current superseding part number HT680054, this transformer converts 120V line voltage down to 24V AC to power every low-voltage control circuit in the furnace — including the thermostat, control board, gas valve, and inducer relay. When this transformer fails, the entire control circuit goes dark: the thermostat displays nothing, the furnace will not attempt ignition, and no low-voltage components respond. A failed transformer is often misdiagnosed as a bad control board, making it the smart first part to test and replace.

  • Specs: Primary Voltage: 120V AC | Secondary Voltage: 24V AC | VA Rating: 40VA | Frequency: 50/60 Hz | Phase: Single | Mounting: Foot-mount | Dimensions: approx. 3" L × 2-3/16" W × 2" H
  • OEM vs Generic: This OEM unit ships in a Carrier factory-authorized box and is wound to exact factory VA and voltage tolerances. Generic transformers commonly run under-spec VA ratings, causing nuisance tripping, overheating, and premature control board damage — a risk not worth taking on a furnace this size.
  • Install difficulty: 2/5 — Switch off power at the breaker and confirm zero voltage before disconnecting any wires. Photograph all wiring before removal. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, multimeter. Verify 24V output at C and R terminals on the control board after installation to confirm correct operation.
  • Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered by 5 PM local time.

Compatibility: Directly fits Carrier model PG9MAA060140AEKA gas furnace. Also replaces legacy Carrier/Bryant/Payne transformer part numbers HT01BC116, HT01BC115, HT01BB126, HT01CT120, HT01BC120, HT01AW115, HT01AA012, HT01AQ110, HT01CT210, HT01CT20006, 322666-701, 322953-302, and B1810113. Confirm primary voltage (120V) on your unit's data plate before ordering. Order now and our team will verify fitment before your part ships.

Frequently Asked Questions

Does this Transformer fit my Carrier PG9MAA060140AEKA?
Yes. This is the factory-specified OEM transformer for the Carrier PG9MAA060140AEKA. 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 PG9MAA060140AEKA?
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.
