Re: Zanussi ZNB 4051
How to access these components in the Zanussi ZNB 4051:
1. remove all freezer drawers, shelves etc.
2. remove back panel – there are two screws under obvious grey caps
3. remove vent panel at the top/front (it has the door switch in it)
This is the awkward bit.
There are 4 clips:
Two are obvious on the underside of the panel. These can be lifted carefully with a thin screwdriver and prised open. The clips will bend slightly but if careful won’t snap. they should stand out for a while before slowly returning to their original position.
The other two are hidden at the sides. They can be accessed via small openings at the very edge of the panel. The clips themselves are oriented at 90 degrees to the opening so you will be coming at them from the side. You have to come at them directly from below with a flat shamfered blade so that upward pressure will open the clip outwards. A normal screwdriver won’t work because the angle of attack is wrong due to the screwdriver handle getting too close to the freezer casing. The only tool I can think of would be a screwdriver with a very thin handle, but a 1.4 inch blade.Once all 4 clips have been freed, the vent panel can be removed by pulling forwards. This will provide access to the door switch.
4. Once the vent panel is removed, there are 2 hexagonal crews holding the curved top panel in place. Removing these provides access to the fan, thermisters and other components.
The alternative to removing the vent panel first would be to drill a 1/2 inch hole in the square flat coverings of the hexagonal screws (located one at each end of the back edge of the vent panel). This will provide access to the hexagonal screws. Removing these will drop the curved top panel and vent panel together. All the vent panel clips can then be accessed directly.
The final alternative is to go in blind and end up breaking off the square flat coverings described above. This is what happened to the engineer in my case. :rolls:
For information it was the freezer door switch that was the problem. A new switch and vent panel are being ordered and we bodged the switch so the fridge will work in the mean time.
