Description
Temperature Controller (Thermostat) for Refrigerators and Freezers WPF14B-EX / WPF14-8C40 (250V 5A, 2 pins)
The WPF14B-EX series mechanical temperature controller (thermostat) (marked WPF14-8C40) is designed to maintain a set temperature and automatically control the compressor's on/off cycle in domestic refrigerators, chest freezers, display cases, and wine coolers. It features a rotary adjustment stem for a control knob and a two-pin connection group.
Key Advantages and Features:
- Precise Cooling Control: The rotary stem provides smooth and accurate adjustment of the desired temperature mode.
- Electrical Reliability: Rated for operation in domestic power grids with 250V and a load current of up to 5A, ensuring resistance to voltage fluctuations.
- Versatility and Ease of Installation: The two-pin connection scheme (2 Feet / 2 terminals) simplifies the installation and replacement of a failed thermostat.
- Protective Capillary Tube: The sensor's capillary tube is placed in an insulating sleeve to protect against mechanical damage and short circuits.
Signs of a Faulty Thermostat:
- The refrigerator compressor runs continuously without shutting off, causing food to freeze solid.
- The refrigerator stops cooling completely, while the interior light stays on and the compressor does not start.
- The temperature inside the chamber is unstable and deviates significantly from the value set on the control knob.
Compatibility and Application:
Widely used in single-chamber and double-chamber refrigerators, freezers, mini-fridges, wine coolers, and commercial refrigeration equipment from various brands (Indesit, Ariston, Candy, Beko, Nord, Snaige, Haier, Midea, LG, Samsung, etc., using WPF series thermostats):

Technician's Tip: When replacing the thermostat, carefully unroll the capillary tube, avoiding kinks and sharp bends, as this will lead to refrigerant/gas leakage from the bellows and failure of the new thermostat. The tip of the capillary tube must fit tightly against the evaporator in the standard fixing clip.
