My shop is heated with a very old propane-fired Reznor hanging furnace. At the end of last winter it stopped working.

I do not hear the familiar click when the thermostat is raised above ambient temperature, and the furnace does not fire.

The pilot is lit and the thermocouple is about two years old. There is plenty of propane in the tank. The gas valve is open.

Where should I look for the failure?

I would check to see if the thermostat wire is good and is the low voltage transformer working.

If the T-stat don't not click no more, that's where I'd start.
