1. Tools needed and safety first

All you’ll need is a pair of long nose pliers, a 14mm socket, if you have one and a Phillips screwdriver.

Firstly, eliminate all power to the fridge freezer. 

2. Remove the thermostat housing

To make accessing the thermostat housing easier, remove any items and the shelves.

Remove temperature control knob

Pull the temperature control knob towards the inside of the fridge to remove it.

Remove the nut

The nut can be removed with the 14mm socket, or a pair of long nose pliers to loosen it and then unscrew.

Remove the screw

With your Phillips screwdriver, unscrew the long screw holding the thermostat housing in place.

3. Remove wire connectors

Before removing any wires, take a photo of the existing wiring layout. The earth wire may need removing with the long nose pliers.

4. Remove old thermostat

You can now gently slide the existing capillary out of the fridge freezer.

5. Install new thermostat

With your new thermostat, carefully insert the capillary into the hole until you feel some resistance. 

Re-connect wiring

Using the photo you took earlier as a reference if needed. The earth, green and yellow wire, connects to the single bottom connecter.

With the remaining three connectors that are in a line, connect the double brown at the bottom, the single brown in the middle and then the double black at the top.

6. Re-attach thermostat housing

Now put the thermostat housing back in place. To make this easier, firstly thread the metal piece (circled orange) from the thermostat through to the other side of the thermostat housing. Then, re-screw the nut back on.

Slide and connect the thermostat housing to the side of the fridge freezer. Then line up the hole and re-screw the long screw back in.

Re-attach temperature control knob

Whilst turning the control knob, push it towards the temperature unit. It will then slot into place.

Then, re-install the shelves and any items you removed.

And that’s it, your new thermostat centre post is all set to go!
