OEM Carrier Furnace Transformer 120V–24V 40VA for Model PG9MAB060120ABSA (Replaces HT01BC116)

This is the factory-specified OEM step-down transformer for the Carrier PG9MAB060120ABSA gas furnace, sold under OEM part number HT01BC116 (updated to HT680054). The transformer converts 120V line voltage down to 24V AC, powering every low-voltage component in the system — including the thermostat, gas valve, inducer relay, and control board. When it fails, nothing in the furnace responds: no call-for-heat, no fan, no ignition sequence. A failed transformer is often the first suspect when the system is completely unresponsive despite a live 120V power supply.

  • Specs: Input 120V AC | Output 24V AC | 40VA rating | 50/60 Hz | Single phase | Foot-mount chassis | Wire-lead connections with insulated female quick-connect terminals
  • OEM vs Generic: This OEM unit is built to Carrier's exact VA rating and insulation class. Generic transformers are often wound to loose tolerances, causing voltage sag under load — which triggers nuisance lockouts on sensitive control boards. OEM is the only reliable choice for precision furnace electronics.
  • Install difficulty: 2/5 — Turn off all power at the breaker and disconnect the furnace service switch before starting. Photograph all wire connections before removing the old transformer. Tools needed: flat-head and Phillips screwdrivers, nut driver, multimeter (to verify 24V output after install). The transformer mounts with two screws and connects via quick-connect leads — typically a 20–30 minute job.
  • Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day when ordered before cutoff.

Compatibility: Direct OEM replacement for Carrier model PG9MAB060120ABSA gas furnace. This part supersedes OEM number HT01BC116 and is also cross-referenced as HT680054. Verify your existing transformer's primary voltage (120V), secondary voltage (24V), and VA rating (40VA) on your unit's data plate before ordering. Need fitment confirmation? Our HVAC parts specialists verify compatibility before you buy — same-day shipping available on all in-stock orders.

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.
