Good,no refrigeration problems, points to a bad board I mentioned, unless you want to keep the box fan on it permanently.

Ok. I replaced the second control board. Condenser fan now seems to be operating normally (every time I check, it's running).
However, occasionally the compressor will get more noisy (same noise, just louder) and the freezer temp will elevate. It's like clockwork: compressor noise increases, check the temps, freezer is elevating, divider gets hot, eventually temps go back to normal.
Ideas?
Chris

If you have a meter, I would start by monitoring the voltage to the fridg from the wall outlet, seems like you have a power problem.

I have a basic multi meter, but nothing that would record activity. Do I need a long-term record, or just to monitor for a few minutes? What am I looking for? Chris

The inverter box has a discolored spot on the side away from the compressor that is warm to the touch.

Your inverter box might be overheating and shutting down periodically. I would check inside to confirm.
Also,measure the input voltage to the fridg when you have a problem.

Also,measure the input voltage to the fridg when you have a problem. Compressor is currently more noisy than normal. Freezer temp is 7F, but this seems to be the "normal" temp when the compressor is noisy. Voltage at the wall is 122.5 +/- .1. Chris

Evidence points to a bad inverter box, unfortunately, there is no easy way to test the compressor except to install a new inverter box. One way to verify the inverter box is bad is to check the total current into the inverter box. Lower than normal current would confirm a bad inverter box.

One way to verify the inverter box is bad is to check the total current into the inverter box. Lower than normal current would confirm a bad inverter box. I have a new inverter box (purchased from here), and I'm trying to install it, but I'm having a tough time getting to the connectors on the compressor. I've got the other connectors disconnected and the inverter box out on the floor, but I can't figure out how to get the black plastic cover off of the connector box on the side of the compressor. Without this cover off, I can't get to the connectors at all. What's the trick to getting that cover off? Thanks, Chris

Never mind. I got it. New inverter is installed and fridge is plugged back in. Fan and compressor kicked on right away. I've got my fingers crossed.
I also added a 1-outlet APC surge protector to perhaps prevent this fro happening again.
