Hello and thanks for using this service, if you have been waiting do not worry or get upset. I am HVAC Guru an extremely experienced tech on the site and I try to get to as many customers as I can. I just picked up your question now. NOTE it takes time for me to type research and add links so please wait for me to respond back I can only do this so fast. Secondly I am not paid anything until you rate my service good using the STAR RATING LINK at the top of your page, the money is paid to the site not me directly. Answer: Based on what you are saying you either blew a low voltage fuse on the board if you have one, but if you have 24 volts to the board and 120 to the unit I would say the board was damaged not much else would cause that issue. All I ask is please use the Star Rating Link at the top of your page before leaving, that is the only way I am paid anything through the are greatly appreciated so thank you very much for using this service. If you have any other questions just post back to me here anytime!
