Lennox G40DF-60D-135 Transformer
A basic electrical transformer is quite common in electrical appliances including your HVAC system and it converts the electrical output from a particular voltage to a different one. Heating and cooling transformers are all different and you must follow specific volts and amps requirements. If you are going to replace a transformer, make sure to get one that is measured to the right voltage that will be needed by the system.
Red flags your Lennox transformer needs to be replaced
- The transformer shows damage or maybe smells burnt while the system is turned on
- Incorrectly sized volts can be measured coming from the chief transformer
- No power calculated at the output of the HVAC transformer whatsoever
