I’ve got a 20 year old Westinghouse furnace. I don’t see a model number on it. It has been upgraded at some point with an automatic ignitor. I replaced the belt on it yesterday. I left the front panel off to make sure the belt was fine when the furnace was running. Stupidly, I left the cover off as I went to make dinner. After 20 minutes or so our CO sensor went off. This sensor is not the battery powered type; it is on one of the household circuits. I immediately turned off the furnace and put the cover back on. It was at this point I saw the “Do not operate furnace without this cover in place” sticker. Dumb. Anyway, after having the windows and doors open for 45 minutes or so, I attempted to restart the furnace. The ignitor is clicking but the furnace will not actually ‘kick’ on. I have absolutely no experience working on furnaces and really don’t now exactly how they operate but I’m guessing that when the CO alarm went off it somehow disabled the furnace. I’ve looked for a reset button on the furnace but can’t find one. I turned the breaker on/off and have unplugged the furnace for an extended period but these things didn’t work either.
What am I missing here? Any advice is much appreciated as it is getting pretty cold here!
