OEM Carrier Control Transformer 120V–24V 40VA for Model PG9MAA048060AFKA

This OEM step-down control transformer is the factory-specified replacement for the Carrier PG9MAA048060AFKA gas furnace. The transformer converts 120V line voltage to 24V AC, powering the entire low-voltage control circuit — including the thermostat, gas valve, inducer relay, and ignition board. When this transformer fails, the furnace goes completely dead: the thermostat loses power, no call for heat is processed, and the system will not attempt ignition. A failed transformer is often misdiagnosed as a board or thermostat fault, making correct identification critical before replacing more expensive components.

  • Specs: Primary voltage: 120 VAC | Secondary voltage: 24 VAC | VA rating: 40VA | Frequency: 50/60 Hz | Phase: Single | Replaces OEM part number HT01BC116 (superseded by HT680054)
  • OEM vs Generic: OEM transformers are wound to exact factory VA and voltage tolerances, protecting sensitive control boards from under- or over-voltage conditions. Generic units often lack built-in overcurrent protection and can fail prematurely under normal cycling loads.
  • Install difficulty: 2/5 — Shut off furnace power at the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Label and photograph all low-voltage wiring before disconnecting. Verify 24V output at secondary terminals with a multimeter before reassembly.
  • Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Fits Carrier model PG9MAA048060AFKA gas furnace. This part supersedes OEM part number HT01BC116. Always verify your unit's data plate voltage and VA specifications before ordering. Our parts specialists are available to confirm fitment — order with confidence.

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?

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.
