Model DGAA077BDTA - red light and alarm
Posted: Mon Jul 28, 2008 1:03 pm
My unit is about six years old. Since we got it, occasionally when a breaker trips, my alarm has gone off and the red light flashes. As soon as I figure out which one it is and get everything back on, the alarm stops. Yesterday though the power in the town went out for a second and came back on. The alarm went off and the red light is flashing, but after the power came back on the alarm and light did not stop. I checked all of the outlets to see if any had popped, but they are all in tact. Everything is in the on position in my panel. My unit is working/cooling fine. I turned the alarm to the off position so I didn't have to listen to it. I have contacted two different HVAC companies, and no one has heard of an alarm on a unit before. They suggested I contact Coleman, which I tried, but could not get a live person.
I assume it is electrical. I do not see anything listed in the panel for an attic fan. There is a note that says "Lockout Supplies: dishwasher, attic fan, furnace, water heater." I don't know what that means.
A friend of mine turned the gas off, but I just recently turned it back on. I assume that is okay since the unit is working okay.
Can you tell me how to get this alarm off? Thank you so much !
