______________________________________________________________________ I have a Coleman Evcon gas furnace in a rental house. The ignitor does not glow when the thermostat calls for heat. The circuit board has a red light that flashes 5 times, pauses, then repeats continuously. Does anyone know if this flashing light is diagnosing and signaling a specific problem? Appreciate any advice on this unit.

It’s his furnace and his responsibility, not yours. You break it and you may have to pay for a new one. Otherwise, call a professional who has liability insurance, have him fix it and send the bill to the landlord. rl25292 “Re(2):Flashing Red Light on Coleman Evcon” , posted Sun 28 Nov 15:02 ______________________________________________________________________ I work for the landlord but don’t have much experience with Coleman furnaces and circuit boards.

What is the translation for 5 blinks? rl25292 “Re(4):Flashing Red Light on Coleman Evcon” , posted Sun 28 Nov 22:24 ______________________________________________________________________ I found the problem, which was a tripped heat limit switch. I reset the switch and everything returned to normal operation. This was apparently caused by a clogged filter. So I guess 5 red flashes on the circuit board indicates a tripped heat limit switch. Thanks for those who responded. The boss is happy and I get to keep my job for another day.
