Universal Freezer K50-P1117, Replaces Freezer Thermostat Kit 333XP
If your refrigerator or freezer is running too warm, too cold, cycling constantly, or not cycling at all, a failed temperature control thermostat is the most common cause. In most single and multi-door refrigerators and freezers, the cold control thermostat monitors compartment temperature and signals the compressor to cycle on and off to maintain the set temperature. When it fails, the compressor either runs continuously (freezing everything) or stops cycling entirely (allowing food to warm). ⚡ Common failure point across a wide range of refrigerator and freezer platforms. Part 333XP is the premium XPart universal thermostat kit that replaces K50-P1117 and WPF29R-103-022 and restores accurate, stable temperature control immediately.

Is This the Right Part?
Confirm the complete model number before ordering. Similar parts may use different connectors, dimensions, hose positions, electrical ratings, or mounting points.
- ✔ Refrigerator/freezer powers on and compressor runs (or ran recently)
- ✔ Condenser coils are clean and condenser fan is confirmed working
- ✔ Door gaskets seal correctly — no visible gaps or tears
- ✔ Evaporator fan confirmed running and airflow is present in the compartment
- ✔ ONLY problem is temperature too warm, too cold, or compressor not cycling correctly
- Refrigerator not cold enough — food spoiling faster than normal
- Freezer or fridge too cold — items freezing that shouldn’t be
- Compressor runs continuously without cycling off
- Compressor won’t start even though the unit has power
- Temperature fluctuates widely regardless of thermostat dial setting
- Thermostat dial turns freely but has no effect on compartment temperature
- Part Number: 333XP (XPart universal thermostat kit)
- Type: Universal cold control thermostat kit — temperature sensing switch with capillary tube for refrigerator and freezer compartment control
- Replaces: K50-P1117, WPF29R-103-022 (no modification required for compatible applications)
- Compatibility: Universal fit — suitable for a wide range of refrigerator and freezer models across multiple brands. Verify your existing thermostat’s temperature range and capillary tube length before ordering.
Before ordering, turn the thermostat dial to its coldest setting and listen for the compressor to start — if it starts, the thermostat is likely the issue. If the compressor doesn’t start at all, the problem may be the start relay or compressor itself. A $5 multimeter test across the thermostat terminals (should show continuity at coldest setting) confirms the diagnosis in under 2 minutes and prevents an unnecessary part order.
