Lennox CB28UH-042 Transformer
A basic electrical transformer is quite common in electrical appliances which includes your forced air system as it is used to convert electrical output from one that is higher to a lower voltage. If any transformer needs to be swapped out, be sure to purchase a transformer that is correctly rated for the voltage so that you get an exact match. Heating and cooling transformers are specialized components and you should be aware of the specific necessary voltage readings.
Main clues your main transformer needs replacing
- System transformer physically appears cracked or you might notice sparking when in use
- Not a single volt evaluated leaving the system transformer while being tested
- Incorrectly sized volts is calculated from the output of the system transformer
