OEM Carrier 50VA Control Transformer 120/240-24V for Model UPFLOW080UAAC14A

This genuine OEM control transformer (part number P201-35150) is the factory-specified replacement for the Carrier UPFLOW080UAAC14A upflow gas furnace. The transformer steps down your household line voltage to the safe low-voltage signal your furnace's control circuitry depends on every heating cycle. When the transformer fails, the entire control circuit loses power — thermostats go dark, the board stops responding, and the furnace will not attempt ignition at all.

• Specs: 50VA rating | Primary voltage: 120/208/240 VAC multi-tap | Secondary voltage: 12/24 VAC | Single phase | 60 Hz | CSA listed | Factory part number P201-35150
• OEM vs Generic: This is a genuine Carrier/Totaline factory part, wound to exact VA and voltage tolerances. Generic transformers are often under-rated in true VA capacity, causing premature thermal cutout trips and nuisance lockouts — particularly under heavy control circuit loads.
• Install difficulty: 2/5 — Disconnect power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (verify 24V output after install). Photograph or label all low-voltage wiring before disconnecting from the old transformer.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered for the Carrier UPFLOW080UAAC14A upflow 80% AFUE gas furnace. The multi-tap primary (120/208/240V) makes this transformer compatible across standard residential and light-commercial supply voltages. Always verify the VA rating and secondary voltage on your unit's wiring diagram or data plate before ordering. Have a fitment question?
