Does anyone know on why my coleman evcon DGAT070BDC gas furnace will only light the furnace sometimes and not all the time like it should. I can see the electric ignitor lighting up but will not light then it retries to light but sometime it will and sometime it won't. everything seems to be working...

check the power on the transformer? see picture below to locate line and load side.

I forgot to tell you, look for a round black switch with a red button in the center. I just ordered a new one from this site as mine is taped together. Looks like the button they put in turkeys, just push in the red button in the center and furnace will come back on.

mine had the same symptoms and it was a upper limit switch. If the furnace overheats it cuts everything off. I bet that this is your problem.

There is an upper limit

switch to the left side top of furnace just under the edge.

I have found a coleman evcon furnace manual with the parts list and the part number shown on the list says its: 7624A3591 Upper Limit Switch. I have ordered this switch from you. Can you double check for me and make sure I ordered the right part? My furnace model is coleman evcon DGAT070BDC. Thanks ...

The temperature rise says: 45-79 F

thanks for all of your help. The set temperature on the thermostat seems to never get to the set temperature. At night I put the thermostat on 80 degrees at night and it still is cold in my home.

Furnace is in a newer mobile home 1995 century 16x80

The reading at the closest supply register is 82

The furnace warms up like it should then the fan comes on but only runs about 5 minutes at a time, then fan shuts off and the cycle starts over.

The model of the furnace is DGAT070BDC The air coming out of the ducts is warm air and not hot like it should be. any help will be greatly appr...

My leak is around the flue for the furnace. I have installed an electric nordyne furnace and when I took all the pipe off for the gas furnace which I don't need anymore it now leaks, I have tried a tar like product and it sealed some of it but not all of it. I went all the way around the pipe and it...

The duct connector is what the picture shows. My problem is that I have an air leak between the furnace and the duct connector.
