Fujitsu ASU18CL Transformer
A transformer is used frequently in anything electrical which also includes your heating system and it transforms household electrical current from one that is higher to a lower voltage. When one needs replacing, be sure to purchase a transformer that is correctly rated for the correct voltage that is desired. Heating and cooling transformers can all be different so make sure you meet the voltage and amperage needs.
Warnings to watch for in a failing unit transformer
- System transformer looks like it is ready to fall apart or may look broken when being used
- Incorrectly sized volts is measured from the output of the system transformer
- Zero volts measured from a main transformer while using a measuring device
