How to replace Fridge freezer circuit board with Digatal Temperature Controller


This video can be used on all fridge,freezers and chest freezers plus 100's of fridge freezer like. AEG, Arthur-Martin-Elux, Bosch, Electrolux, Hotpoint, Husqvarna, John Lewis, Indesit, Neff, Privileg, Rex, Rosenlew, Siemens, Zanker, Zanussi. we are working on a Bosch Fridge Freezer with a faulty circuit Board.



This Graph shows what is happening in this fridge freezer after we changed the temperature controler

As you can see after setting up the fridge at 2 degrees with a hysteresis of 3 the fridge is cycling between 2 and 5 degress

the freezer is set up on -17 with hysteresis of 2 degrees and is cycling between  - 15 and 18 degrees

it will always need some calibration depending on where you fit the sensors

Before you begin you need to find which controller is best for your fridge freezer.

  • you also need to find the best fitting location.
  • remember always fit in a place where the wiring can be added  easily and that you have enough space to fit the unit.
  • also think where the refrigeration pipes are so you don't damage them when fitting.

    I have a John Lewis freezer model JLW6006.
    Last week the alarm went off and I was able to cancel the alarm but not the flashing red light. Although the food is slightly softer, especially ice-cream It has not altogether thawed the contents. I have put the freezer to quick freeze setting but still it not not reach the set minus 18. The red light continues to flash the entire time. The freezer is 7 years old but not opened every day perhaps only once or twice a week. It is not overstocked as to reduce airflow inside. I live on a small pension and cannot afford a new freezer of this quality again at the moment. I would like to try to repair it! It is likely to be a thermostat problem or PCB issue? If so, is a PCB easily replaceable? Any advice warmly welcomed. Thank you.
