Question about Coleman Heating & Cooling
SOURCE: Rudd furnace
You have a safety limit switch that is either bad or needs to be manually reset. Some have little buttons between the two wires going to the switch that you can push to reset. If not they are automatic switchs then one is bad. You have to do an ohms test to see if each switch is bad or good.

I have a thermostat 9600 Robertshaw and I have to use the trip switch to start my furnace. Then it reaches the temperature and sometimes it will kick in by itself but majority of the time I have to trip it. I have changed the batteries cleaned the thermostat,and reset it. Is it time for a new thermostat and can I replace it myself. Thanks

Check inside the door panel next to the wiring schematic, you should find the diagnostic codes. Look up 7 blinks. This should narrow down the problem. ( It sounds like a bad hot surface ignitor).
