WDF18-L, WDF20-L, and WDF19-K are refrigeration temperature controls suitable for household refrigerators and installed in the freezer compartment. WDF22-L and WDF24-L are freezing temperature controls suitable for deep freezers and small single-door refrigerators with operation desks. (Not applicable for refrigerated display cabinets, beverage display cases, or commercial freezers.) Selection criteria: 1. Confirm if the original unit is WDF type or WPF type (the two types are not interchangeable). 2. The exact model number does not need to match, but must be the same type and used on similar refrigeration equipment. 3. Check if the appearance and mounting method are compatible. Ensure the probe length is sufficient. Longer probes can be shortened; shorter probes are generally not interchangeable.
