Got a similar problem. Our built in runs all the time. I have to keep the top panel off or it won’t cool all the way. Got a repair guy out a couple weeks ago and he suggested rebuilding it. For a couple grand. Which seems really steep until you realize that to replace it would be 8-10 grand. We decided to rebuild it mostly because we didn’t want to do a remodel. If I was considering a remodel, then I think buying a new one would be justified. But if I rebuild it and get another 10 years out of it, it’s worth it.
