Fridge issue

[TOMMY47]

A few months ago, after I drove on a very bumpy road, Fridge quit working on gas. Freezer was fairly cold but main compartment NOT.
Worked on it by cleaning burner and putting back together--worked great.
This week I decided to defrost freezer because it was not cooling the main part of fridge as it should . Defrosted quick and restarted. Freezer worked so-so but main compartment--NOT.
Decided to take burner apart again and noticed that the gas supply valve had moved a fraction--not real noticeable. Moved the valve back in place and secured it better and works fine again.
Something to look at if the fridge cooling lessens, while on gas operation, rather than paying a fortune on repairs.

It is that horizontal slot to the left of where I connected a manometer in this picture, you turn it vertical to turn off the gas. Turning it a little lowers the flame quite a bit.

Could you post a pic of the valve or send me one via eMail?
