OEM Carrier Furnace Control Transformer 120V/24V 40VA for Model PG9MAA060080AEKA

This OEM Carrier control transformer (part# HT01BC116 / successor HT680054) is the factory-specified step-down transformer for the Carrier PG9MAA060080AEKA gas furnace. It converts 120V line voltage to 24V AC to power the entire low-voltage control circuit — including the thermostat, gas valve, inducer relay, and control board. When this transformer fails, the result is immediate and total: the thermostat goes dark, the furnace locks out, and nothing responds. No clicks, no ignition attempt, no blower — the system is completely dead.

  • Specs: 120V primary | 24V secondary | 40VA rated | Step-down class-2 transformer | Wire lead connections | Direct OEM replacement for HT01BC116 (current successor: HT680054)
  • OEM vs Generic: OEM transformers are wound to exact factory VA and voltage tolerances, protecting sensitive downstream components like the IFC control board. Generic units can run undervoltage under load, causing intermittent lockouts and premature board failure.
  • Install difficulty: 2/5 — Shut off power at the breaker and confirm voltage is absent before disconnecting. Tools needed: flathead and Phillips screwdrivers, multimeter, wire nuts or spade connectors. Photograph all wiring before removal. Verify 24V output at C and R terminals on the control board after install.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.

Compatibility: Engineered for Carrier model PG9MAA060080AEKA gas furnace. Cross-references: HT01BC116, HT01BC116B, HT01BC115, HT01BC120, HT01BB126, HT680054, and additional Carrier/Bryant/Payne part numbers. Always verify primary voltage (120V) and VA rating (40VA) on your unit's data plate before ordering. Our team is available to confirm fitment before you buy.

How do I replace the transformer on my Carrier OEM Carrier Furnace Transformer 120V/24V 40VA — PG9MAA060080AEKA?

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.
