What is the resistance supposed to be on the heating coils?

Don’t know the actual resistance but a common mistake that people make when testing heaters are not unhooking the power wires. Unhook at least one side, either red or black before testing continuity. You will then find your problem. Likely a bad limit switch, not coil.

Have a Evcon Coleman Furnace shows three green

I have had the same problem with mine for the last 2 years. Remove the motor on the side of the furnace(usually held on by 3 screws) and turn the fan blades inside by hand. after sitting all summer it seems to get stuck. If it moves freely, replace the motor and try to start it again. This fixed mine the last 2 years! Hope this helped.

Coleman Mach ac with airxcel thermostat will only turn on in high cool mode.Thermostat wont turn on in fan mode low or high. And wont turn on in auto mode low/highcool. Here humming in low/high auto.

If you are hearing humming from the motor itself, replace the capacitor. Should only cost you $10-20. To rule out a faulty thermostat perform a jump test on the control board. There's a lot of videos and tutorials online for performing a jump test. I attached one of them for your reference, however with the humming, I am inclined to believe it is a faulty capacitor.
