Part NumberWP2183400 Replaces2183400, 2162052, 2162044 ManufacturerWhirlpool Appliance TypeRefrigerator Part TypeDefrost timer, 8 hour ✅ Cross Reference Information Current Part NumberWP2183400 Replaces2183400, 2162052, 2162044 Common Symptoms Heavy frost or ice buildup on the freezer evaporator area Refrigerator section becomes warm while the freezer remains relatively cold Freezer runs continuously or for unusually long periods Refrigerator or freezer stops cooling when the timer remains stuck in defrost Defrost cycle starts but the appliance does not return to cooling operation Check Before Replacing Disconnect appliance power before accessing the timer, wiring, or nearby components. Inspect the timer connector and wiring for loose, misplaced, or damaged connections; do not rely on symptoms alone because the heater, defrost thermostat, and wiring can produce similar conditions. With power disconnected, inspect for excessive evaporator frost that could indicate a defrost-system problem. If qualified to perform electrical testing, verify the defrost heater and defrost thermostat separately before condemning the timer. A qualified technician may manually advance the timer into defrost and verify whether the compressor stops and the heater circuit is energized; live-voltage testing presents shock and fire hazards. Pro Tip A defrost timer can appear to work when advanced manually yet fail to advance automatically. Confirm that the timer receives its motor power during normal operation before replacing it. Part Details Part NumberWP2183400 Part TypeDefrost timer, 8 hour ManufacturerWhirlpool Appliance TypeRefrigerator Primary FunctionControls the refrigerator’s automatic defrost cycle by periodically switching the appliance between cooling operation and defrost-heater operation on an approximately 8-hour schedule. Installation Notes Disconnect power before installation. Document or photograph the existing wire-terminal positions before removing the old timer. Transfer the wiring to the corresponding terminals on the replacement part; incorrect terminal placement can prevent the timer from advancing or cause improper operation. The timer may be retained by plastic clips or a mounting arrangement; release the retaining features carefully to avoid breaking them. After installation, restore power and confirm that the appliance returns to normal cooling operation; allow the refrigerator to complete its operating cycle before judging performance.
