bar cooler not cooling

hi, i am a newbie here and a fairly new commercial kitchen repair tech,i have a service call tomorrow for a bar fridge/beer cooler that is only cooling to 50 dg. the owner said he turned it off for a few minutes and then turned it back on and it worked again for a couple of days,i dont know the brand yet but i will check that out tomorrow. my first plan of action is to clean the evaporator and surrounding parts and check the refrigerant p/t,any other help would be appreciated:cool:

If it’s a skybox, it’s probably not repairable, if it’s something else post the model # and i’m sure someone will help you.

Thanks for your reply,the brand is true manufacturing ,didn’t get the model # but I cleanded the compressor lines and evaporator with a quality evap cleaner and so far so good ,its cooling at 36 degrees now

Never heard of it.. But glad just cleaning it worked for you.
