OEM Carrier 50VA Control Transformer P201-35150 for Model UPFLOW100FAUAC14

This is the genuine OEM factory replacement transformer for the Carrier UPFLOW100FAUAC14 upflow air handler. The transformer steps down incoming line voltage (120/208/240 VAC) to a safe 24V signal that powers all low-voltage control circuits — including the thermostat, control board, and zone valves. When this part fails, the entire control circuit goes dead: the system won't respond to the thermostat, the blower may run continuously, or the unit may refuse to start at all.

• Specs: 50VA rating | 120/208/240 VAC primary input | 12/24 VAC secondary output | 60 Hz | Single phase | CSA listed | OEM part number P201-35150
• OEM vs Generic: This is a factory-matched Carrier/Totaline OEM transformer built to exact VA and voltage tolerances for the UPFLOW100FAUAC14. Generic transformers often run underrated VA, causing premature overload failure and voiding system warranties.
• Install Difficulty: 3/5 — Always shut off power at the breaker and confirm voltage is zero before touching any wiring. Tools needed: flathead and Phillips screwdrivers, multimeter, needle-nose pliers. Label all wires before disconnecting, and verify primary tap selection matches your supply voltage (120V or 240V).
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
