International Comfort Products PGME30G0904 Transformer
A transformer is used in many applications including your HVAC system and it converts the electrical output and switches it to a different voltage range. If you have to replace a transformer, make sure you buy the one that is rated for the correct voltage that is needed. Heating and cooling transformers are all different and you must follow specific electrical requirements.
Major clues of a defective transformer
- Wrongly displayed volts is determined from the output of the system transformer
- The volt dropping transformer physically looks damaged or may smell burnt when it is in use
- No power is measured from the output of the transformer block using a voltmeter
