How do you adjust the Dometic thermistor?
How do you adjust the Dometic thermistor?
To adjust the temperature in a Dometic RM2652, you are to move the plastic slide up to make the fridge colder. The plastic slide that holds the thermistor in mine was loose. Loose enough that when I slide it up the fin, the thermistor slide down the sleeve. Moving the slide did nothing to move the thermistor.
How does the Dometic thermistor work?
A Thermistor is a simple resistance based thermal probe that changes resistance based on the ambient air temperature. By moving the thermistor from one part of the cooling fins to another you are effectively readjusting the resistance and “tricking” the control board.
How do you determine if a thermistor is bad?
The most common way to know if a thermistor is bad if it starts displaying inaccurate temperature readings. This can be caused by excessive heat, improper handling, a thermal mismatch, or a dip in resistance accuracy due to regular use and age. An open circuit can also lead to thermistor issues.
Where should thermistor be placed?
For best stability, the thermistor needs to be placed as close to the thermoelectric or resistive heater as possible. For best accuracy, the thermistor needs to be located close to the device requiring temperature control.
How do I know if my refrigerator thermistor is bad?
The freezer thermistor, along with the fresh food thermistors, will send signals to the main board so that it can determine when to turn the compressor off/on, speed up/slow down/cut off the fans or open/close the damper. If one of the thermistors is bad the refrigerator will not cool correctly.
What happens if thermistor is bad?
When a thermistor is failing, it’ll display incorrect temperatures, or you’ll see impossible temperature fluctuations. When a thermistor in a car is failing, the AC system will blow cold air for a short time or the blower will stop functioning correctly.
