OEM Carrier 40VA Control Circuit Transformer for Model YAC2460YACX508T

This OEM step-down transformer (part number P201-35150) is the factory-specified replacement for the Carrier YAC2460YACX508T system. The transformer steps line voltage (120V) down to the 24V signal voltage required to power the control board, thermostat, contactor coil, and all low-voltage safety circuits. When this part fails, the entire control circuit goes dead — no thermostat communication, no contactor pull-in, and no system operation of any kind. A failed transformer is often identified by a burned smell, a visibly cracked or melted housing, or confirmed with a multimeter showing 0V on the secondary side.

• Specs: Input: 120V AC | Output: 24V AC | Rating: 40VA | OEM Part Number: P201-35150 | Factory-matched for Carrier YAC2460YACX508T
• OEM vs Generic: This OEM transformer is wound to exact factory VA and voltage specifications. Generic alternatives frequently run outside tolerance, risking control board damage and nuisance blown fuses on the low-voltage circuit.
• Install Difficulty: 2/5 — Disconnect all power before servicing. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, multimeter, wire nuts or quick-connects. Label and photograph all wiring before disconnecting. Check and replace the 3A or 5A low-voltage fuse on the control board at the same time — a shorted load is the most common cause of transformer failure.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
