Lennox G40UH Transformer
A transformer is used in many applications including heating and cooling systems as it is used to convert electrical output from 120V to 24V, for example. Transformers are specialized components so make sure you meet the volts and amps requirements. When one needs replacing, it would be a good idea to buy one that is rated for the correct voltage that is required.
Hints of a poorly working converting transformer
- System transformer physically looks damaged or may smell burnt white the system is on
- Inaccurate voltage is calculated across the transformer
- No power evaluated leaving the HVAC transformer while tested with the unit on
