Question about Coleman Propane Forced Air Heater w/Electronic Ignition (50,000-80,000 BTU)
You should be seeing 120 volts to the igniter. Anything less requires either a replacement of the transformer, start relay or control module.

Maybe not! there is a limit switch that has opened not allowing power to pass and start the furnace. You will need to tale a Ohm meter and follow the wires thru any safety switch. In your case, it may be the thermo-disc near or over the burner box. Jump it out to test it. Now why is your blower not working (which could have been the reason why the thermo-disc opened)? Once you find which safety switch is open and you have jumped it out, take a jumper wire and jump between the R and G terminals on the circuit board. This should start your fan. If not, either the fan is stuck, the fan motor is bad or hopefully noy; the circuit board is bad.

Check to see if the blower motor is actually getting power to it...You will have to check for power on the heating speed terminal... and the neutral wires....you should have 120v across those two wires....
If you have power then the motor is bad...if no power then the heating relay went bad on the circuit board and you will have to replace the circuit board...
That is a common problem as those relays are often to light and wear out...
Just realize that without an electrical meter to trace things through you are really just grabbing at possibilities and not really able to correctly diagnose your problem...
