FengsHVAC a Professional HVAC Tech teach you how to fix Ice Cream Unit from Turkey
Problem: the ice cream unit is not cooling.
Insight: compressor was running, but the temperature was reading about 45 degree, and the evaporator fans were not running, sightglass bubbled.
Solution: there was a leak at the king valve, fixed the leak. I charged the unit about 6LBS of R404a, while the manufacture name plate states 3LBS only. They made a mistake, I charged by superheat and subcooling. when I put in 5LBS, it was still low, so I had to put in 6LBS to make it cool properly. This unit was from Turkey. Hahaha. It's working fine now. The picture show 18 degree, but it drop down to -5 degree at setpoint...
