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.

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.
