I've had 2 curing fridges in the last year. I control the temp using an ink bird temp controller with wifi. I've posted my settings here but both have stopped cooling after about 6 months in the same exact way. I'll add one was a standing fridge and my latest elone that died is a freezer. They were both used but it's weird the they both seem to have died the same way. The compressor sounds like it's running. The compressor is getting hot, the high pressure line is warm and the low pressure is about ambient. I'm at a loss for what's going on.

It's in an open basement with plenty of airflow
