Lennox XC21-036 Transformer
A transformer is used in many applications which also includes your heating system as it usually converts electricity from 120V to 24V, for example. Heating and cooling transformers are specialized components and you should be aware of the specific voltage readings. When any transformer needs to be replaced, it would be good to get one that is assessed for the right voltage value that is necessary.
Major clues of an ineffective electrical transformer
- The volt dropping transformer seems melted or perhaps smokes when it has electricity going through it
- Not a single volt measured from the transformer while tested with the unit on
- Different volts is calculated across the system transformer
