Mitsubishi PKA-A12HAL Transformer
A basic electrical transformer is used frequently in anything electrical including your HVAC system as it is used to convert electrical output and switches it to a different voltage range. If one needs replacing, make sure you buy the one that is assessed for the correct voltage that is necessary. Heating and cooling transformers may have specific specs so make sure you meet the voltage readings.
Subtle hints the transformer has very little life left
- Incorrect voltage is calculated from the output of the chief transformer
- The volt dropping transformer seems damaged have a burning smell while the system is turned on
- No power coming from the system transformer while being tested
