SOURCE: Coleman Evcon model DGATO70BDC Starts to run then stops?

What you have is an ignition problem and your unit is shutting down on safety.

SOURCE: Carrier Weathermaker gas 8000 will not ignite

Your hot surface igniter may be bad. It may be cracked which would prevent it from starting the burner flame.

SOURCE: have a coleman evcon furnace

Your centrifical swith is stuck open on your blend motor. I found that removing the blend motor housing and spinning the stuck motor (from setting over the summer) will get you out of a bind ,.but you may end up needing this centrifical switch (locatedon the bottom of the blend/fresh air intake) motor replaced.

SOURCE: (HVAC) Furnace Not Igniting Quickly

Make sure a back draft in the flue is not happening. Wind can blow it out until the flue heats up. The flame sensor may not be close enough to the burner flame. It may be weak and need to be replaced or if its an optical one it may be dirty and not see the flame very well. Its not wasting much gas but it puts extra wear and tear on the gas controls, is noisy, and, as you said, blows cold drafty air. A gas control system that has issues of any kind is not real safe. It needs to get fixed.

SOURCE: Furnace comes on for 1 min then kicks off, repeats this cycle

MY FURNACE WOULD RUN FOR ABOUT TWO MINUTES , THEN THE BURNER WOULD GO OUT BUT THE BLOWER WOULD CONTINUE TO RUN , LONG ENOUGH TO COOL THE FAN LIMIT SWITCH DOWN , THEN IT WOULD START THE PROCESS ALL OVER. WHAT FIXED MY PROBLEM WAS THE SECONDARY HEAT EXCHANGER THAT IS LOCATED JUST ABOVE MY BLOWER MOTOR WAS PLUGGED WITH DIRT , WHICH RESTRICTED THE AIR FLOW , CAUSING THE FAN LIMIT SWITCH TO REACH 200 DEGREES AND SHUT THE BURNER DOWN . YOU'LL HAVE TO TAKE THE BLOWER MOTOR OUT TO GET TO IT , BUT MY FURNACE IS RUNNING PERFECT NOW

I have a Coleman evcon gas furnace that the blower comes on for no reason . Does not do this all the time . It comes on and runs for about 3 minutes and shuts off . Does this 4 or 5 times in a row .


James, If it has a electronic board, it has a heat sensor built into furnace that turns fan on to get all the heat out of furnace for efficiency. May need adjusted a bit, or replaced.

Furnace wont work


Have to know the model and serial of the furnace.
locate code list usually inside or on the back of a door.
Operation sequence= call for heat--inducer blower motor--makes pressure switch--signals board to bring on hsi--after a set time gas valve opens and you have ignition--main blower motor comes on after a set time

Coleman Evcon furnace. Can i make it circulate air?


Your thermostat should have a "continuous blower" setting. Use that instead of fooling around with the A/C setting

How old is my Coleman Evcon Furnace, Modle Number: DGAT056BDE? I can't seem to find a Manufacturing date sticker. It was claimed to only be a year old, now living here a year it would now be 2 years old. ...


The Serial Number would really help in defining how old your Coleman furnace is. The model you have is used predominantly in manufactured housing. To find the Serial Number, you will need to remove the upper shroud of the furnace. There should be a sticker or plate on the back of that shroud of just inside the housing of the furnace, that will give you the Model # & Serial #. Armed with that, you can do a little detective work, as to it's age.

I have a Coleman Evcon gas (propane) furnace. When the t-stat is switched to heat the furnace heats up but the blower will never turn on. The unit then shuts down and tries to cycle again. I have replaced...


If the unit fires but the main blower fan doesn't come on the the unit is shutting off on a temp high limit switch and it sounds like the problem is the main blower fan motor or control

I have a coleman evcon furnace and it wont work it gives me a flash code of 1 what does it mean


One flash mean ignition failure. The sequence is: T-Stats calls for heat, inducer motor comes on, igniter glows orange (look through glass), then gas comes on and burner lights, approximately 1 minute later the indoor blower comes on. If you don't see the glow, most likely the igniter is bad. If you see the glow but no flame, it's a gas problem, supply or defective valve.
