OEM Carrier Furnace Transformer 120V to 24V 40VA — HT01CN001 for Model UPFLOW150UAHAC14B

This is the genuine OEM Carrier transformer (part number HT01CN001), factory-specified for the Carrier UPFLOW150UAHAC14B upflow gas furnace. The transformer is the backbone of your system's low-voltage control circuit, stepping line voltage down from 120V to a safe 24V (with a 12V tap) at 40VA capacity. When it fails, the thermostat goes dark, the system refuses to respond to any call for heat or cooling, and you may hear a faint buzz or hum from the control panel. Replacing it restores the entire control circuit instantly.

• Specs: 120V primary | 12V / 24V secondary | 40VA capacity | Class 2 control transformer | Foot-mount design | Replaces legacy part numbers HT01BJ115, 19EA41612, and 19EA42612
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part — not an aftermarket substitute. OEM transformers are wound to exact VA tolerances, ensuring stable 24V output under full load. Undersized or off-tolerance aftermarket units can damage control boards, contactors, and thermostats downstream.
• Install difficulty: 3/5 — Turn off power at the breaker and verify zero voltage with a multimeter before touching any wiring. Tools needed: flathead and Phillips screwdrivers, multimeter, needle-nose pliers. Photograph all wire connections before removal. The transformer mounts via a foot bracket inside the air handler cabinet.
• Warranty: 1-year OEM Carrier factory warranty. In stock — ships same business day from our warehouse.
