International Comfort Products PGMD30G0608 Transformer
A basic electrical transformer is used for many products which also includes your heating system as it usually converts electricity and switches it to a different voltage range. Transformers are all different and they should follow strict voltage and amperage needs. If one needs replacing, it would be good to get one that is measured to the right voltage that will be needed by the system.
Symptoms of a worsening main transformer
- Not a single volt calculated leaving the system transformer while being tested
- The main transformer looks damaged or maybe smells burnt while the system is turned on
- Cycling voltages can be measured coming from the main transformer
