RV Repair: Norcold Fridge wont operate on LP mode, jumper wire, empty hole

Question
QUESTION: We are unable to take our RV to a "authorized repairman"!  It is boondocked and was pulled there with a tractor.  Our Norcold 62x, works great on AC (generator) but the LP mode stopped working.  Error code "F" on panel which indicates it's not igniting.  However, we can see the flame, which is deep blue and steady.  Even after it's lit, the electronic ignitor keeps clicking as if it doesn't know it's already lit.  It attempts to light (an already lit flame) for about 45 seconds, then stops trying and generates the "F" error code.  I have read the manuals, but none of the troubleshooting indicates what to do if it's actually lit.  They all assume it's not lighting.  

Any suggestions on how to fix the problem?  What parts need to be replaced?

Many thanks!

ANSWER: clean the part that clicks and then you may try un hooking the thermisiter. it is located by the light in the middel of the fridge and see if that helps will it cool even with the f?

QUESTION: Thank you, will try your suggestions.  And no, it doesn't cool even with the "f" code.  The sensor stops the flow of propane because it doesn't think the burner is lit (even though it is).

Answer
Ok the board is usually bad. and means that the eyebrow or buttons inside are going out too this is and easy fix just hard an the wallet let me know what happens after you clean it also try putting a jumper wire in the top row plug its like a sixteen pin plug on the board i beleve its the first empty hole and that plug on the top going from left to right take a wire and stick it in that empty hole and touch the outher to the back of the fridge wait for the click (20 to 40 seconds) and see if it goes away.
