I need a hot surface ignitor module for my folks furnace. can't find one decent any where. chaney here in town want $213 for it :moonu: I tried a board level repair, but i think the micro is out. It just blinks. according to my liturature this means reverse polarity. I checked this. no problems. the blower blows. limit switches are good and groviding 24vac in/out of board. test terminal yields no codes other than the already present flash. no power to inducer fan.(doesn't turn on during test as it should either) uzzled: it is a hk42f20 and has a black plastic cover. it goes in a 58zav carrier weather maker. Any hvac gurus or suppliers out there? HELP!!!!
