A transformer is used in many applications including heating and cooling systems and it transforms household electrical current from one that is higher to a lower voltage. Transformers are specialized devices so be sure you replace it with the same volts and amps requirements. If you have to replace a transformer, it would be good to get one that is rated for the correct voltage that is essential for the system to run properly.
