Friedrich MW12Y3H Transformer
A basic electrical transformer is used frequently in anything electrical including heating and cooling systems as it transforms electricity from 120V to 24V, for example. Heating and cooling transformers can have different specs and they should follow strict necessary voltage readings. When you replace one, be sure to replace it with one that is properly rated for the exact voltage that is demanded.
