OEM Carrier 50VA Control Transformer P201-35150 for Model UPFLOW080UA14A
This OEM step-down transformer is the factory-specified replacement for the Carrier UPFLOW080UA14A upflow gas furnace. The transformer converts incoming line voltage (120/208/240 VAC) down to 12/24 VAC to power the furnace's control board, thermostat, and all low-voltage control circuits. When the transformer fails, the entire low-voltage control system goes dead — symptoms include a blank thermostat display, a furnace that won't respond to any call for heat, or a repeatedly tripped 3-amp fuse on the control board.

OEM vs Generic: This is a genuine Carrier factory-authorized part (Totaline/Replacement Components Division). OEM transformers are wound to exact VA and voltage tolerances required by the UPFLOW080UA14A control board. Generic transformers often run outside ±5% voltage tolerance, risking nuisance board faults or premature control board failure.

Install difficulty: 2/5 — Shut off power at the breaker and confirm zero voltage before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Label or photograph all low-voltage wiring before disconnecting. Check and replace the 3-amp control fuse if it was blown before installing the new transformer.

Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.
Compatibility: Engineered for the Carrier UPFLOW080UA14A upflow gas furnace. Verify your unit's data plate shows a 50VA transformer requirement and 120/208/240 VAC primary voltage before ordering.
