A genuine OEM thermistor for Thetford “N-series” and “3000-series” absorption / electronic fridges. Designed to monitor temperature inside the fridge and send signals to the control board to regulate cooling. If your fridge is over- or under-cooling, or showing error codes, a faulty thermistor is often the cause.

For accurate temperature control and efficient fridge performance, the thermistor must be in good working condition and correctly located. This part replaces worn or damaged sensors to restore proper operation.
