Our Selma, California area technician responded to a refrigeration request at a pharmacy today. The freezer had been leaking and considerable ice had built up. Ice was melting and refreezing during every defrost cycle, causing water to leak. After inspecting the system, found that the drain tube heater misaligned and not positioned properly in the drain tube. Fixed heater position, confirmed part is running correctly, and cleared ice/leftover water. Freezer is online and leak issues resolved.
