Question about Air Conditioners

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

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.

We have a coleman evcon furnace. The furnace runs constantly. It'll get to the temperature but then the fan doesn't quit and it only blows out cool air the the reset switch pops up and needs to be be...


It sounds as if your furnace is exceeding the limit tempperature of the manual reset switch. The coleman is designed for the fan to continually run when this limit switch is tripped in order to keep the heat exchanger cool.( it is a safety feature) afew things may be happening.
1. the manual limit switch( the one you have to push) may be defective.
2. The fan may be running at too low of a speed. Turn power off at circuit breaker. locate circuit board on the board there will be one terminal that says heat if the red wire from the blower is on it tthen you may need to up the speed. follow the wires from the blower to the board if it has multiple speeds then you can isolate the red and put the blue or orange on the heat terminal.
3. the board may have an adjustable fan on and fan off pin selector if it is set up to come on to long or go off to soon it may not be controlling the temp of the heat exchanger properly.
4. I would also suggest checking to see if the orifices and gas valve are set up for your sytem correctly.
these are just simple ideas let me know how things go.
