Everchill Fridge Not Cooling

[jspring]

We have a 2020 Puma 28BHSS with an Everchill fridge. I pulled it out of storage this week and have discovered the fridge is not cooling. We’ve not had this problem before. The fan runs in the freezer, but the compressor will not kick on. Fuse and breaker check out fine. I’ve powered everything down and let it sit for a couple hours in hopes that it would reset, but no luck.
Any other tricks I can try or tests I can run on the control board etc..
Thank you for your help!

The model number is always helpful.

The power button can be pushed for 5 seconds to enter self diagnostics mode. I’m not familiar with what the codes mean as I’ve not had a failure yet, it it should be easy to find and get you one step closer.

Now that we’ve pulled the refrigerator out of the cabinet so we could gain access to the back we are hearing 3 beeps/buzzes every minute or so that seems to be coming from the black compressor board. Anyone know what the 3 beeps/buzzes mean?
