OEM Carrier 40VA Furnace Transformer 120V–24V for Model PG9MAA024060ACKA

This OEM step-down transformer is the factory-specified replacement for the Carrier PG9MAA024060ACKA gas furnace. The transformer converts 120V line voltage to the 24V AC signal that powers every low-voltage component in your system — thermostat, gas valve, ignition control board, and zone controls. When this part fails, the furnace goes completely dark: no thermostat response, no ignition attempt, no blower activity. A failed transformer is often mistaken for a bad control board, so always verify 24V output at the R and C terminals before condemning more expensive components.

  • Specs: Input 120V AC | Output 24V AC | 40VA rating | 60 Hz | Foot-mount configuration | Wire lead connections with compatible female connectors
  • OEM vs Generic: This OEM-spec unit is wound to exact Carrier factory tolerances, ensuring stable 24V output under full VA load. Generic transformers are frequently under-rated, causing voltage sag that triggers nuisance lockouts and premature control board failure.
  • Install Difficulty: 2/5 — Shut off power at the breaker and disconnect the furnace before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph existing wire connections before disconnecting. Confirm 24V output at R–C terminals after installation before restoring full power.
  • Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse. Note: OEM part number HT01BC116 has been superseded by direct replacement HT680054 — same specs, factory-authorized substitution.

Compatibility: Designed for the Carrier PG9MAA024060ACKA gas furnace. Also crosses to Bryant and Payne furnace models sharing the same 120V/24V/40VA transformer specification. Cross-reference part numbers: HT01BC116, HT680054, HT01BC115, HT01BB126, HT01BC120. Verify your unit's data plate voltage and VA rating before ordering. In stock and ready to ship — order by 3PM for same-day dispatch.

How do I replace the transformer on my Carrier OEM Carrier Furnace Transformer 40VA 120V-24V — PG9MAA024060ACKA?
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.
