OEM Carrier 50VA Control Transformer P201-35150 for Model UPFLOW080FAUAC14

This OEM control transformer is the factory-specified replacement for the Carrier UPFLOW080FAUAC14 upflow gas furnace. The transformer steps down your home's incoming line voltage — 120/208/240 VAC — to a safe 24V AC signal used to power the control board, thermostat, and all low-voltage circuit components. When this transformer fails, the entire control circuit goes dead: your thermostat goes blank, the furnace won't respond to any call for heat, and no safety sequences can run.

  • Specs: 50 VA rating | 120/208/240 VAC primary | 12/24 VAC secondary | 60 Hz single-phase | CSA listed | OEM part number P201-35150
  • OEM vs Generic: This is a genuine Carrier/Totaline factory-authorized part. OEM transformers are wound to exact VA and voltage tolerances, protecting sensitive control boards from over-voltage damage. Generic units may drift under load, causing erratic thermostat behavior or premature board failure.
  • Install difficulty: 2/5 — Shut off power at the breaker and verify zero voltage before disconnecting any wiring. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal. Spade or screw terminals make reconnection straightforward for most technicians.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed as the direct OEM replacement for the Carrier UPFLOW080FAUAC14 upflow gas furnace. Verify your unit's data plate confirms a 50VA, 120/208/240–24V transformer requirement before ordering. Have a question about fitment?

Is this transformer compatible with Bryant or Payne too?
