OEM Carrier 40VA Control Transformer P201-35150 for Model UPFLOW080FAU14A

This is the factory OEM replacement control transformer (part number P201-35150) for the Carrier UPFLOW080FAU14A upflow gas furnace. The transformer steps down 120V line voltage to the 24V AC signal used by the control board, thermostat, gas valve, and all low-voltage components. When it fails, the entire control circuit goes dead — your thermostat will appear unresponsive, and the furnace will not initiate any heating cycle regardless of thermostat demand.

• Specs: 120V primary → 24V secondary | 40 VA rating | Factory-matched OEM replacement | Designed to Carrier's exact impedance and thermal protection specifications
• OEM vs Generic: The OEM P201-35150 transformer meets Carrier's precise VA rating and short-circuit protection requirements. Generic alternatives can under-deliver on VA capacity, causing nuisance control board lockouts or premature transformer burnout under normal load.
• Install Difficulty: 2/5 — Disconnect power at the breaker and verify zero voltage with a multimeter before beginning. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, multimeter, wire nuts or quick-connect terminals. Note wire colors and terminal positions before disconnecting the old unit.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
