OEM Carrier 50VA Control Transformer P201-35150 for Model YAC2480YAC106C

This OEM Carrier transformer (part number P201-35150) is the factory-specified step-down transformer for the Carrier YAC2480YAC106C packaged unit. It converts incoming line voltage (120/208/240 VAC) down to a safe 24 VAC to power the system's control board, thermostat circuit, and other low-voltage devices. When this transformer fails, the entire control circuit loses power — symptoms include a completely unresponsive thermostat, a system that won't start at all, or blown low-voltage fuses that keep recurring due to insufficient power delivery.

• Specs: 50VA capacity | Primary: 120/208/240 VAC | Secondary: 12/24 VAC | 60 Hz single-phase | CSA listed | Factory OEM part number P201-35150 (also cross-references Totaline HCTY156D0LS11102)
• OEM vs Generic: This is the genuine OEM factory part, precision-wound to exact VA and voltage tolerances for the YAC2480YAC106C. Generic transformers may carry ±10% VA tolerances, risking under-voltage conditions that cause nuisance lockouts and premature control board failure.
• Install difficulty: 2/5 — Shut off all power and verify zero voltage before beginning. Tools needed: multimeter, screwdriver set, wire stripper, needle-nose pliers. Label all low-voltage wiring before disconnecting. Check and clear any short circuits in the 24V control wiring before installing the new transformer to prevent immediate failure.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
