Based on the info you have given here, I am going to make some assumptions. In "cleaning out all the components" you cleaned the air filter or changed it, cleaned the duct-work, and the intake combustion chamber? When the "furnace stays lite" the pilot and the main burner stays on? Lastly, when it "continues to blow cold air" is this when the main burner is on after long periods of time? If the answers are all yes, then maybe some of the ducts have come off, or the burners aren't working correctly.

Goodman GMP Furnace problem. Original problem is

Good one! Is the flame getting to the flame sensor within the few seconds? Maybe a good cleaning of the burners or flame tray would help. 1.3 ma is enough for the flame rod to tell the board to stay on. Re-do all the ground connections both at the board and furnace cabinet to be safe. Check the polarity of the power going to the furnace. What are the chances the second board is bad?

Gas furnace; flame will not stay on

Clean the flame sensor with a green scotch brite pad. Check all ground connections from the circuit board to the furnace cabinet. Check for a proper ground to the electrical box. Make sure polarity has not been reversed.

Coleman furnace -- fan runs, ingniter won't light,

The chances are that the furnace was running when the power went out. This will cause the high limit switch to cutout and needs to be manually reset.
You will find that switch in the blower compartment near the blower. Usually somewher near the highest point of the cabinet.
Push the little red button firmly till it clicks.
When the power goes out while the furnace is running the heat builds up because the blower shuts down immediately and causes this limit switch to cut out.
If you have a electric tester you can also follow the low voltage circuit till you find the open switch. Ther is usually a wiring schematic on the door cover of most furnaces.

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

Coleman presidential II furnace blower on and off

Sounds like the flame sensor. But it could be the thermostat. Is the furnace standing pilot or electronic spark or hot surface ignition. I would start by checking thermostat. Turn power off to furnace take thermostat off wall and take wires marked r & w and connect them together. Turn power back on if furnace works then change out thermostat.Most eclectronic ignition Furnaces have a flam sensor, You could take flame sensor out and clean it up with steel wool or wire brush. If you need anymore help just reply back .

Coleman Presidential II mobile home furnace. When burner lights the blower cycles on and off instead of blowing constant through burner cycle.

Is this furnace standing pilot or electronic ignition. If standing pilot i would check furnace filter then the thermastat. To test themostat first turn power off to furnace. Take thermostat off wall and take wires labled R & W and connect them together. If you have electronic ignition I would start with cleaning the flame sensor with steel wool or wire brush.If you have and more questions i will be glad to help.

Heater blower motor cycles on and off (frequently). I have a class 2 LR95329 Honeywell Thermostat

The clicking noise is a relay or switch of some sort. You are right about that. I have 2 questions. 1) does the thermostat have a mercury bulb in it? 2) when the fan shuts off and on, does the burner stay on?
