Weekend refrigeration call for a weight loss center in Arcadia, California. One of their Traulsen freezers was going down. Tech arrived and found freezer #4 with a frozen evaporator. The evap sensor was reading 87 degrees, way off temp. Tech put unit into manual defrost, confirmed defrost was working confirming sensors had failed. Had coil and cabinet sensors on truck, was able to replace same day. Tested system after repairs and unit working again.
