Possible bad pressure switch?
My Weatherking gas furnace Model GDWHE060B-D3 has been intermittently not lighting. The fan would come on and run for a long time but I'd have to power off the furnace and wait then power it back up to get it to try to light again and sometimes it would sometimes it wouldn't. I got on this and other forums and read a few things to try which I did and one seemed to help. In one of the articles I read it said to remove the tube from the blower to the pressure switch and blow/suck on it to make sure the valve isn't stuck. When I did that it seemed to help. Well I think I may have blown a little too hard this time and popped the diaphragm because it made a pop sound when i blew into it. Now the furnace won't even attempt to light (I don't here the autopilot clicking at all). I've got it powered off for now. I'm assuming I've ruined the pressure switch, can I simply buy a new part swap it out and be done or is there more to it than that?
Thanks for any help in advance.
