If this is an older furnace, it is probably a wearing fan control.
Some can be adjusted, otherwise they need to be replaced.

Do I need a outside cooling unit for a Coleman 7900 Presidential lll gas heat and cooling unit


Yeah, youd have to look at the model on the Indoor coil box, furnace will be setting on top of it. Youll need the model off that coil box to get the correct tonnage of the outdoor condensing unit, you can go 1/2 ton smaller on outdoor for greater efficiency.

True air heat tries to start then goes to gas.It worked fine in the fall but it is now -5F


Do you have a heat pump and gas furnace setup? Or is it electric and gas setup.

To me it sounds like either configuration issue its electric and gas, but if its heat pump/gas the furnace is defaulting to gas more then likely on the outside air temperature, usually most heat pumps only heat good down to 10 degrees F.

Burners burn for a few minutes and them goes out and fan continues to run even though their are no flames and have three quick flashes on the board


Hi,
On the back of the bottom cover for the blower compartment there will be a key to tell you what the three flashes mean....probably telling you that it did not light...meaning you have a bad ignitor...


Here is a tip that will help you try to figure out why your furnace is not working.

Air conditioning runs all the time


I assume this is a manufactured home, this is probably a two transformer system, either your contactor is welded in the on positon or wyou have control wiring issues, (could be the thermostat)

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.

Coleman forced air furnace


im assuming you are running a/c and not heat...Was the filter burning??  if not and there are no other obvious burnt wires then id say you need a new motor. The filter, if it was'nt binding the blower wheel or wrapped arround the motor shaft would not have caused the prob.
