Hi, I'm Robert. Welcome to JustAnswer. I'm reviewing your question now and will post back with your reply momentarily.

It also appears the solenoid valve isn't allowing the gas pilot to light.

ON your flue canister look for a tripped thermo-fuse, if that is tripped then the fridge will not turn on, if the fridge has been running you need to let it cool off before it will reset, click HERE and see picture, it will say thermofuse. IT is really small about the size of a quarter or slightly larger and in the center is a tiny button.

IF you still need more help please let me know, IF you are satisfied with my efforts please feel free to select a STAR rating on the page....

When that trips it will prevent the fridge from doing anything it is a safety.

I will check it out. Can I continue to reach out to you or do I have to start the session again from the start?

You can respond back as needed, I am around daily and respond when I can, please keep in mind I only get credit when you select a STAR rating on the page, you can still follow up with me if needed.

Thanks Robert
