Universal Refrigerator K50-P1118, Replaces WR09X32545 Temperature Control Thermostat Kit
If your refrigerator 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 standard refrigerators, 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 platforms. Universal Refrigerator K50-P1118 is the premium XPart universal thermostat kit — cut-in 7°C / cut-out 3°C — that replaces WR09X32545 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 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
- Fridge not cooling — compressor not running or running only briefly
- Fridge running constantly — never cycling off, freezing everything
- Temperature swings — food spoiling even though fridge feels cold
- Fridge too warm even at coldest dial setting
- Items freezing in the fresh food compartment
- No response when adjusting the temperature dial
- Part Number: 777XP (XPart universal thermostat kit)
- Type: Universal cold control thermostat — mechanical temperature sensing switch with capillary tube, cut-in 7°C / cut-out 3°C
- Replaces: K50-P1118, WR09X32545 (no modification required for compatible applications)
- Compatibility: Universal fit — verify your existing thermostat part number or confirm your model uses equivalent cut-in/cut-out specs before ordering
A thermostat that tests fine electrically but the fridge still won’t cool usually points to a failed start relay or compressor — not the thermostat. The bypass test above takes 2 minutes and eliminates guesswork. If the compressor starts on bypass, order 777XP with confidence — it’s your fix.
