Thanks for your question,
more than likely it would be your Flame sensor, it is more than likely dirty and needs cleaning, it is the rod that the flame impinges on when the unit lites off, if it is dirty then its a matter of removing it and cleaning it with emery cloth, or replacing it, cleaning is the cheaper alternative, just look at the front of the burners, and you will see a pencil thin rod, thats your flame sensor, should be just one 1/4 hex head screw holding it in place, a quarter inch nut driver works great for this, then remove, clean, and reinstall, make sure you have the power off while preforming this task, hope that fixes your problem. please leave a rating for this, thanks again,

I have a EVCON furnace DGAT070BDC. I replace the igniter control, the gas valve and the thermostat. Same problem continues: glow stick works, then the pilot lights works.The igniter control clicks...


You may have a dirty/rusty burner that is clogged or your gas valve
manifold pressure setting may be too low. Normal manifold pressure
is 3.5 inches water column on natural gas furnaces. ( 1 psig is equivalent to 28 inches water column). Pull and clean burner. Also
check and clean pilot assy. including flame sensor (if present).
Please let me know.

Coleman Evcon Furnace Model G8T10012UHB11A


you probably have a cracked heat exchanger which is causing the rollout switches to trip.even the tiniest of cracks will cause the fan to blow the flame back into the unit and cause them to trip. check the heat exchanger for even the tiniest of cracks if so replace it. and be sure to have a carbon monoxide alarm in your home.

I have a Coleman/Evcon Presidential ser# 074878. The plumber says the Heat exchanger is cracked. Is this something I can fix myself or is it less expenxive to buy a new furnace?


The heat exchanger is a bear to change. depending on the age of the unit it might be more practical to replace the unit. However unless you trust this service tech I'd get a second opinion, because it is rare that a heat exchanger will crack, plus by law he or she should have shut the furnace down do to carbonminoxde. Especially rare in Coleman Evcon series units.

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.

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