OEM Carrier 50VA Control Transformer P201-35150 for Model UPFLOW150UAHAC14

This is the genuine OEM factory-specified control transformer for the Carrier UPFLOW150UAHAC14 upflow air handler. The transformer steps down high-voltage line power (120/208/240 VAC) to safe low-voltage control power (12/24 VAC) that energizes the system's control board, thermostat circuit, and all low-voltage accessories. When this transformer fails, the entire control circuit goes dead — the thermostat goes blank, the system won't respond to calls for heating or cooling, or a downstream short can cause the transformer to hum loudly and blow its internal fuse. Replacing it with the correct OEM unit restores full control circuit operation immediately.

• Specs: 50 VA rating | Primary: 120/208/240 VAC | Secondary: 12/24 VAC | 60 Hz | Single phase | CSA listed | OEM Part# P201-35150
• OEM vs Generic: This is the genuine Carrier/Totaline factory part engineered to exact VA and voltage tolerances for the UPFLOW150UAHAC14. Generic transformers often run undersized VA ratings, causing premature failure under sustained load or when multiple accessories share the control circuit.
• Install difficulty: 2/5 — Shut off power at the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Identify and photograph all low-voltage wiring before disconnecting. Check for a downstream short before installing the new transformer to prevent repeat failure.
• Warranty: 1-year OEM factory warranty included. In-stock and ships same business day from our warehouse.
