Have HVAC Questions? Ask an HVAC Expert for Answers
Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here, I try to get to as many customers as I can and I just picked up your question now. Please give me time to respond as typing, researching and adding links takes me time to do so. Please be patient and often I will ask you questions to narrow down the issue to get you an accurate diagnosis.
Do you have a volt meter?
If the Green or RED indicator LED is not on flashing or doing anything on the board you may have a power issue to the unit itself, can you see if anything is on or flashing on the board?
OK yes then you need to check your incoming power to the unit, either you have lost your 115 volts to the unit or the transformer maybe bad. Check that and let me know. ALso physically install new new fuse on the board just in case.
