OEM Carrier 50VA Control Transformer P201-35150 for Model UPFLOW080UA%14

The Carrier P201-35150 is the factory-specified OEM step-down transformer for the UPFLOW080UA%14 upflow gas furnace. This transformer takes incoming line voltage — 120, 208, or 240 VAC — and steps it down to a safe 24V AC signal to power your furnace's control board, thermostat circuit, and all low-voltage system controls. When the transformer fails, the result is immediate and total: nothing on the low-voltage side works. No thermostat response, no ignition sequence, no inducer start — essentially a completely unresponsive furnace.

• Specs: 50VA rating | 120/208/240 VAC primary | 12/24V secondary | 60 Hz single-phase | CSA listed | Carrier OEM P/N: P201-35150 (Totaline)
• OEM vs Generic: This is the exact factory-matched OEM transformer. Generic replacements often use thinner core laminations and lower-grade windings that run hotter, shortening service life. OEM guarantees the VA headroom your UPFLOW080UA%14 control circuit was designed around.
• Install difficulty: 2/5 — Shut off power at the breaker and confirm zero voltage with a multimeter before touching any wiring. Tools needed: flathead and Phillips screwdrivers, multimeter, wire nuts or quick-connect terminals. Photograph all wiring connections before disconnecting the old unit. Mount the new transformer securely to avoid vibration-induced terminal fatigue.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered for the Carrier UPFLOW080UA%14 upflow gas furnace series. Verify your unit's line voltage (120V or 240V) matches the primary tap you intend to use. If your control board or thermostat is completely unresponsive, test the transformer secondary for 24V output before condemning the board — a failed transformer is a common and often-overlooked root cause.
