The pilot flame goes out when the thermostat knob is moved from the off position to the desired temperature setting. Could this be caused by a faulty high limit switch and how do you check it?
To test, jump the two leads on the high limit. However, this sounds most like a faulty gas valve. Most high limits are designed to cut off both the pilot and the main buner.

remove connections from hi-limit switch, and put an ohm-meter across connections then heat it with a match or heat source of that temp range,heat the face and watch your meter it will show open when hi limit reaches cutoff limit/if you need exact cutout temp,you will need to have one of those digital read-out temp gun

Check if the unit receives the right amount of fuel as stated on its nameplate, if it does, check all wires for loose connections, Milli volt wont pass on loose wiring. If this does not correct the problem, you have to replace the gas valve, the main valve coil may be shorted that's why the pilot is shut when main valve is energized.

Try to spray wd40 on knob.
If spraying wd40 doesn't work, you have to replace the gas valve.
