Worked on reach in cooler by front. Upon arrival unit seemed to be off. My controller was completely blank and no power present at controller. I was getting a short to ground. Traced short to main power cord. Disconnected cord from wall and checked. It was no longer shorted to ground. Found breaker 14 labeled at “receptacle” tripped. Tried to reset breaker and it trips immediately. Customer must contact electrician to remedy this issue. Once power is established to unit I could further diagnose. Mod: Steven M
