so after 7 years of excellent service my True TDB-24-48 stopped cooling. first I thought it was the temp controller but switching it out did not do anything. Everything is running as it should in terms of compressor being ON and fans operating and coils being clean. I called a million service guys but the residential guys don’t work on it since it’s a commercial unit and the commercial guys don’t work on it since it’s in a residence. Go figure. anyone has any suggestion/ recommendation for a service tech for this situation in Boston area ? lastly the course of events was as follows: leading up to the failure I noticed a few days before that the cans felt like had warmed and then cooled rapidly as they were a little wet to the touch. Then the internal temp went up to 45F and after that down to freezing. following this the unit stopped working. coils are not frozen btw and the drip tray is empty too. my current guess is a Freon leak but if that’s not it I have no clue.
