SOURCE: My honeywell gas suspended garage heater will not

The pilot light has to be lit before gas valve will operate. That's a safety feature so the valve won't open and fill the garage with gas and possibly cause an explosion or fire. If you have a standing pilot and can't get pilot to stay lit, it's usually the thermocouple and it will need to be replaced. Once the pilot is lit, the gas valve comes on and heats the combustion chamber up to approx. 100° to 125° a thermostat controlled fan switch will close and bring the blower on.

Make sure the pilot is clean (Blue flame fully enveloping the top portion of the thermocouple) if its dirty the pilot will be yellow like a candle and barely touching the thermocouple ...quick fix is knock the pilot with a screwdriver...gently tapping it...knocking the dust out and getting a better pilot....the pilot could also be too small if its not making good contact with the thrermocouple....there could also be an Auxillary limit wired into the thermocouple which when open will prevent the magnet from staying closed....if all looks fine then the Gas Valve itself is likely gone (The magnet inside is not field repairable)

SOURCE: Old reznor gas heater lights up but fan does not

Hi,usually when a heater doesn't "Kick in" it has got to do with the thermistor and or thermostat. The actual thermistor is the best place to start. However with older gear, it is very prudent to get it checked out professionally, as any problems may be fatal... there are indeed strict laws regarding the servicing of ANY Gas equipment due to the possible dangers associated with any mistakes, that said though there is no reason why one cannot check and replace these components, just be careful and follow any instructions.
Also sometimes the regulators can become faulty, this is another thing to remember to check.
If the Fan isn't working then most likely it to do with the thermostat or maybe it is the BI-metallic strip or Thermal Fuse, or the main controller, or the actual fan motor itself, or perhaps if a capacitor if used, this too may gone faulty, one simply has to work through and test each part to isolate the exact cause.

Your problem lies in the gas valve, it looks as if the solenoid is stuck in the open position.
