Friedrich MR12C1H Transformer
A transformer is used frequently in anything electrical which includes your forced air system and it transforms household electrical current from 120V to 24V, for example. If a transformer needs replacing, be sure to buy one properly rated for the correct voltage that is demanded. Transformers can all be different so be sure you replace it with the same voltage needs.
General indicators that your the unit transformer is failing
- Extremely low voltage measured from the HVAC transformer for whatever reason
- Inaccurate voltage is calculated from the output of the main transformer
- System transformer seems melted or may look broken when it has electricity going through it
