Question about Heating & Cooling

1 Answer

The repairman said there was excessive rust and the area was pitted near the heat exchanger. The furnace is a Coleman EVCON Model BGD12520 about 11 years old. Could this be residue from the burner or something else the repairman saw with his extension light? He said the furnace would have to be replaced and he wouldn't turn it on because of the danger.

If he said there is rusted heat exchanger he was right not to start the unit . you can only call for a second opinion and have a nother repairman confure the heat exchanger is beyond its life. and then ask if there is replacement exchanger avalable for your furnace if its not to old this may be a less expensive alternative.
hope this helps you

please post fead back

Burner flame going out on windy days on Coleman Evcon LP furnace


This sounds like a bad heat exchanger. It is possible that you do not see the crack because the crack is closed when the heat exchanger is cold (or room temp). Allow the furnace to heat up, this will allow the expansion of the crack. Turn the power off and examine the heat exchanger while it is still hot.

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.

You can contact John Stone supply at www.johnstonesupply.com for a store in your area. They can tell you anything you need to know about warranties, they are a Coleman distributor. You can get the parts from them or they will recommend a service company.

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.
