Thermo fuse in Dometic Fridge

My fridge is a DM2652 manufactured in 2013 and I purchased the trailer new in 2014. I have tried running on propane twice and both times the thermo fuse blew. Both times the fuses failed within 30 minutes.

After the first failure I installed a Dinosauer brand circuit board and a 152 degree thermo fuse. The gas valve area behind the tin cover plate appears clean. I have not tried digging into the chimney burner area.

Any good ideas of what is causing n the issue or what to check?

I just took these pictures. The thermo fuse is not in these pictures because I removed it in order to run on AC while camping this week. It had been secured in the clamp in back. Click image for larger version

Most likely the flue is dirty and overheating causing the thermofuse to melt. Try cleaning the flue and baffle and see if it helps.

Thanks for the quick reply. The only way I can see would be shooting air up through the bottom, into the inner tube where the flame burns. Am I correct?

There's a procedure in the manual for cleaning the flue and baffle. It's a bit of a pain, but in your case I think it's worth it.
