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 and 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 is diagnosed correctly.
What make and model unit do you have and do you have an ECM blower motor?
Ok have you checked to see if the capacitor for the blower motor is bad? Does ti sound like the blower struggles to get going?
Can you see the wiring diagram on the panel? If so can you take a picture of it and upload it here?
