Problems with Furnace

My furnace will not kick on when I have my thermostat set to Auto. It kicks on when I have it set to On, but it blows out cold air. I have a York Diamond 80 with a White Rodgers 50A50-241 mother board.

On is just the blower fan nothing else, check to see if there is a reset button in the tstat or tripped over load inside the furnace, inside the furance is some safetys, you will see wires runing from each other and finaly to the gas valve, push each untill one of them clicks,then your furnace should start back working, but I would still have someone come out and check why it tripped, because as I said it is a safety, and when it tripps it is for a reason.

Auto/On set to ON. Fan runs.

Sounds like the thermostat, the way to verify is to unplug indoor unit, remove thermostat, take pic of wiring with phone or label the wires as to the terminals. Carefully twist the yellow,(Y) Red (R) and the green (G) together. Plug the furnace back in, if the unit operates normally, replace the thermostat. I am basing this on the fact that the blower speed is changing. This could also be an anomaly within the circuit board in the furnace section, not likely though as the outside unit (condenser) is not controlled n by the indoor board unless this is a heat pump. hope this helps.

Make sure all vents are open and filters are clean. Likely an air flow issue but possibly, though unlikely, both switches are bad.

Coleman Evcon furnace. Can i make it circulate air?

Your thermostat should have a "continuous blower" setting. Use that instead of fooling around with the A/C setting

Does the furnace stays off?.
Furnace are ment to cycle on and off because of limits .If you set to 70 furnace would cycle several times before reaching that temperature.
Just make sure your filters are clean and you got proper return air flow because lack of air flow will cause furnace to shut off sooner than normal

My heater blows cold air why? I have a REAB 1010s need manual

Check your thermostat to see what your fan switch is set on. There should be two settings - auto and on. If it is set on auto, the fan only comes on when furnace runs. If the switch is set on on, the fan on your furnace is running all the time. Which means when temperature in the house reach what you have set on your thermostat, the furnace kicks off, but the fan keeps running and blows cool air. Some people run their fan all the time, especially if they have allergies, because that's a good way to clean the air.
