OEM Carrier 50VA Control Transformer 120/240–24V for Model UPFLOW180UAHAC14

This is the OEM factory-specified replacement transformer for the Carrier UPFLOW180UAHAC14 upflow air handler. The transformer steps down incoming line voltage (120/208/240 VAC) to a safe 24 VAC to power the system's control board, thermostat, and all low-voltage control circuits. When this component fails, the entire control circuit loses power — resulting in a completely unresponsive thermostat, a furnace or air handler that won't start, or intermittent lockout faults that are difficult to diagnose without testing transformer output directly.

  • Specs: 50VA rating | Primary: 120/208/240 VAC | Secondary: 12/24 VAC | Single-phase | 60 Hz | CSA Listed | OEM Part # P201-35150
  • OEM vs Generic: This is a genuine Carrier/Totaline OEM part engineered to exact VA rating and voltage tolerances for the UPFLOW180UAHAC14. Off-brand transformers frequently run under-rated VA, causing overheating, nuisance tripping, and premature control board failure.
  • Install difficulty: 2/5 — Disconnect all power before starting. Tools needed: flathead and Phillips screwdrivers, multimeter, wire nuts or quick-connect terminals. Label and photograph all wire connections before removal. Test 24V output after installation before reassembling cabinet.
  • Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day from our warehouse.

Compatibility: Designed and factory-matched for the Carrier UPFLOW180UAHAC14 upflow air handler. Verify your unit's data plate matches OEM Part # P201-35150 before ordering. Have questions about fitment? Our HVAC parts specialists are ready to confirm compatibility before you buy — don't wait for a cold night without heat.
