nurkvinny Posted February 14, 2006 Report Share Posted February 14, 2006 I am searching the web for ya, not much coming up in the searches. You have a space heater or anything? Quote Link to comment Share on other sites More sharing options...
Boost-n-Juice Posted February 14, 2006 Author Report Share Posted February 14, 2006 thanks guys. we're good. looks like it has a bad hi limit sensor (thing that looks like a credit card, w/2 wires coming out of it) I bypassed it and runs fine and it is within the degree range of 35-65, difference between intake and exhaust. Damn, I'm an expert now thanks to google. We're going to heat the house up and run a space heater for the night and I'll replace the part tomorrow.

Sam1647545489 Posted February 14, 2006 Report Share Posted February 14, 2006 If you need any help fixing that or any other heating problem, my friend is a good HVAC guy. Let me know and I will call him if you need anything fixed or looked at. Quote Link to comment Share on other sites More sharing options...
Browning Posted February 14, 2006 Report Share Posted February 14, 2006 My furnace is starting this thing where you can hear a small boom before the heat kicks on. I think the house is about to blow up. Quote Link to comment Share on other sites More sharing options...
Dave1647545494 Posted February 14, 2006 Report Share Posted February 14, 2006 be carefull letting it run with the hi limit bypassed the burner can overheat the furnace and then burn your house down Quote Link to comment Share on other sites More sharing options...
