walk-in cooler temperature sometimes drops – walk-in cooler repair in San Jose, California
Customer’s walking cooler didn’t operate properly. Sometimes temperatures gets around 50-60F and all food was spoiling. After diagnostic I found that pressure switch on low side doesn’t sense the pressure. And doesn’t turn off the compressor then thermostat inside cooler reached needed temperature. For that cause compressor was overheating and stops working by thermal relay on compressor. After replacing pressure switch walking cooler was fixed. Everything started working fine. And temperature started been accurate 37F.
