OEM Carrier Control Transformer 40VA 120V/24V for Model UPFLOW175U6019A

This OEM replacement transformer (part number HT01CN001) is the factory-specified control circuit transformer for the Carrier UPFLOW175U6019A upflow gas furnace. The transformer steps down line voltage (120V) to the 24V low-voltage signal used by the thermostat, control board, gas valve, and all safety circuits. When this part fails, the entire control circuit goes dead — the thermostat displays nothing, the furnace won't respond to any call for heat or cooling, and no diagnostic fault codes will appear because the board itself has no power.

• Specs: 120V primary | 24V secondary output | 40VA rated | Class 2 transformer | Factory-matched OEM fitment for HT01CN001
• OEM vs Generic: This is a genuine OEM Carrier transformer built to exact VA and voltage tolerances. Generic transformers often run undersized VA ratings, causing premature thermal cutout trips and repeated control board brownouts that can damage downstream components.
• Install Difficulty: 2/5 — Shut off furnace power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output after install). Label and photograph all low-voltage wiring before disconnecting from terminals.
• Warranty: 1-year OEM factory warranty included. Orders ship same business day from our warehouse when placed before cutoff.

Compatibility: Engineered as a direct OEM replacement for Carrier UPFLOW175U6019A upflow furnaces. Always verify your existing transformer's primary voltage, secondary voltage, and VA rating against your unit's data plate before ordering.
