OEM Carrier 50VA Control Transformer 120/240-24V for Model UPFLOW080FAUAC14A

This OEM Carrier control transformer (P201-35150) is the factory-specified replacement for the Carrier UPFLOW080FAUAC14A upflow gas furnace. The transformer steps down 120/208/240V line voltage to a safe 24V AC signal used to power the control board, thermostat circuit, and all low-voltage components throughout the system. When this part fails, the entire control circuit goes dark — you'll see symptoms like a completely unresponsive thermostat, no ignition attempt, or a furnace that does absolutely nothing when a heat call is initiated.

• Specs: 50VA rating | 120/208/240V primary | 12/24V secondary | 60 Hz single-phase | CSA listed | Industry-standard foot-mount configuration
• OEM vs Generic: This OEM Carrier/Totaline unit is wound to exact factory tolerances, ensuring stable 24V output under full load. Off-brand transformers frequently under-deliver VA capacity, causing nuisance lockouts or premature control board failure.
• Install difficulty: 2/5 — Turn off all power to the furnace at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output post-install). Label or photograph all low-voltage wiring before disconnecting from the old transformer.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier UPFLOW080FAUAC14A upflow gas furnace. Verify primary voltage configuration (120V or 240V) on your unit's data plate before installation. If your system is wired for 208V, this multi-tap transformer accommodates that input as well. Have a fitment question? Our HVAC parts team confirms compatibility before you order — no guesswork required.
