about the only way I can figure is to let the room get very cool and adjust the thermostat to its lowest setting. now turn on the unit. monitor the heat until the stat just opens. the thermostat bimetal will be closed and will open when the bimetal expands and opens its contacts. another way is to hitch up a chart recorder to measure temperature with its output connected to the heater. [too expensive for you or the DIY to accomplish]

You need to remove the covers from the unit and blow out the gas lines with compressed air. If you can remove the gas lines blow out the lines and what they connect to like the pilot light and main feed line to the burner. Usually they gunk up with use and just need to be blown out with compressed air to clear the lines again. Maybe you have some dirt or foreign object from your gas tank which has clogged the line. Also check the igniter electric lines as well and make sure everything is connected properly. Especially make sure you tighten the gas lines you remove. Hope this helps.

Judging by your pics (helpful, by the way) you have a high limit wired into your thermostat wire. Try disconnecting that wire nut connection in front of your valve and hooking the thermostat straight to the top and bottom posts on the valve (eliminating the high limit). If it runs fine, either the connection was poor or your high limit wire is pinched.

Check with Ebay seller s.a.w.inc for available thermocouples. If that doesn't solve the problem the valve unit will likely need replaced.
