I have a comfortmaker furnace that is about 10 years old. Yesterday, the burner came on when the thermostat called for het, no problem. When the called for heat was reached, (68 degrees) it shut off as its supposed to do. I noticed that 30 minutes later, it turned on again, but blower was just pushing unheated air. I checked the burner, and it was not lit, and it continued to run for 30 minutes this way till I cut power to the furnace. Module in furnace was not flashing any code so Im confused. I shut the unit off for the night, and have started it once again to see if t6hat repeats again. since manual gives the fault codes, and none were flashing, I hope someone here can help diagnose the problem. I have a Fasco inducer blower on this furnace and also was wondering if anyone knew where to get parts for it, or the best place to get a replacement for a decent price. These things go for about $280.00 retail!! I have no. 7062-3593 type U62B1. I need to replace just the squirel cage and the cover to the unit. fan cage broke and wore a hole in the cover. Had to spend almost 300.00 to fix a 20.00 problem.
Any help will be appreciated.
