Product Details

The Carrier 11203103002659 is a genuine OEM control circuit transformer designed for use in Carrier HVAC systems, including furnaces, air conditioners, heat pumps, and air handlers. Control transformers are a critical component in any HVAC system, responsible for stepping down line voltage to the low-voltage 24V signal used by thermostats, control boards, relays, and zone valves.

Key Features:

  • Genuine Carrier OEM replacement transformer engineered to exact factory specifications
  • Steps down line voltage to 24V secondary output for thermostat and control circuit operation
  • Maintains correct mounting footprint and lead configuration for direct replacement
  • Designed for reliable, long-term performance in residential and light commercial HVAC applications
  • Ensures compatibility with Carrier control boards, zone valves, and relay circuits

Using a genuine OEM Carrier transformer ensures proper voltage regulation and protects sensitive downstream control components. A failed or undersized transformer can result in the HVAC system failing to start, erratic thermostat behavior, or blown control fuses. Professional installation is recommended.

Great price,fast shipping, no issues!!

shopping from thmotorsports was an easy, enjoyable process. The items came fairly quick and were exactly what the product looked like while shopping.

Ordered a tire and received a tire. Took a couple days after shipping tag was created for it to actually ship, but it was a holiday week. Came pretty quick after the FedEx tracking was updated.

Ordered 4 winter tires, which were affordable and in brand new condition. Shipping was fast. 5 star service.

Delivery was later than expected

Ordering my tire was a breeze. The website was easy to navigate and I received a delivery within the time frame I requested. I would recommend thmotorsports.com.

All went well.
