Part number \u003cstrong\u003eP201-35150\u003c\/strong\u003e, this single-phase transformer converts incoming line voltage (120\/208\/240 VAC) down to a safe 24V AC output to power the furnace control board, thermostat, and all low-voltage control circuits. When the transformer fails, the entire control circuit loses power — symptoms include a completely unresponsive thermostat, a furnace that won't start, or a blown 3-amp fuse on the control board that keeps blowing on reset.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 50VA rating | Primary voltage: 120\/208\/240 VAC | Secondary voltage: 12\/24 VAC | Single phase | 60 Hz | CSA listed | Totaline\/Carrier OEM factory part\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact factory VA ratings and insulation class, protecting sensitive control boards from voltage fluctuations. Generic off-brand transformers frequently run outside rated VA tolerance, risking control board damage and nuisance fuse failures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Shut off all power to the furnace at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, wire labels or masking tape. Photograph all wire connections before disconnecting. Note: a blown transformer is often caused by a short downstream — inspect thermostat wiring and the control board before powering up the replacement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
