My furnace stopped working after the power went off
Posted: Sat May 08, 2010 6:01 am
I have a Coleman DGAA077BDTA and it was working fine. The power went out when the furnace was running, and when it came back on the furnace wasn't making hot air OR shutting down even when I turned the thermostat off.
I followed the instructions on how to reset it (Turn off Thermostat, turn off gas line, turn off power, wait 5 minutes...reverse order to turn it back on), and it still doesn't work. As soon as turn the power back on (with the thermostat still off), it turns on automatically and keeps blowing cold air. I'm getting the Error light to blink 4 times, which means "Limit Switch Open". Anyone know how to fix this?
