A Delfield 2198634 Defrost Heater with Safety Switch prevents ice buildup, enhancing operational efficiency by maintaining optimal conditions within the unit.
The Delfield 2198634 Defrost Heater with Safety Switch supports the refrigeration system by carrying out the defrost function within the equipment's operating cycle. Its integrated safety switch and rated electrical design matter because they allow the part to deliver controlled heat as part of reliable refrigeration performance.
The Delfield 2198634 Defrost Heater with Safety Switch may be nearing the end of its useful life if the unit is not cooling properly, the heater is not heating, the freezer is not freezing or the evaporator coil stays frozen. Performance-related signs can include odor from the unit, a faulty or nonfunctioning defrost element, recurring coil freeze-ups or a GFI trip caused by the defrost element, which might be improved by using a real OEM replacement for longer service life.
