Trying to unscrew bulb cover in a neff oven

Hi,

I'm not familiar with that oven model, but as I have had a similar issue with my Neff oven light, I thought I would give you the benefit of what I had discovered. The light cover in my oven is a round, thick glass cover. The hand book has a graphic showing that the cover is simply twisted with one hand in an anti-clockwise direction as viewed straight onto the cover. No way! The first issue is that the lamp housing is right in a tight corner and getting sufficient grip on the cover is tricky. I put rubber gloves on to increase the grip and resorted to using two hands to exert as much force as I could manage, but it only moved a small amount. I think the movement was only the entire lamp housing moving in the oven wall, rather than any movement of the cover. I tried warming up the oven (not too hot) in the hope that the cover might release due to expansion, but no go. I then wondered if cooking grease / deposits and bonded the cover to the holder; although it appeared reasonable clear. This appears to have been the issue as I applied WD40 to the seam where the glass meets with the lamp housing and left it for a few minutes. It needed a second application, but eventually came free. On inspection, there was only a minor 'varnish' on the glass that appeared to have prevented the two parts from moving. Using WD40 weakened the bond eventually, but it also made the glass incredibly slippery, so gripping the glass cover after application is difficult. I used the rubber gloves and wiped the glass well to remove any residual WD40 prior to attempting to twist the glass cover off.

Most require a simple 1/4" nut driver to remove 2 screws that hold the glass housing over the bulb. Then just unscrew the bulb and install new one.

A length of wood such as a dowel can be used with a mallet or small hammer. Place one end of the wood against the lamp cover so as to force it anti clockwise. Tap the other end gently.

If the unit is less than two years old, cal 0844 892 8999 and ask for an engineer to come out. Alternatively, put on a pair of marigolds, this will help with the grip and remember that the cover comes of anti-clockwise if you are looking up at it. If you do not want to call an engineer out, call the number above and ask them to post out to you the lamp cover removal tool. Part number 613655.
All the best

If it is a round glass cover, then all you need to do is grip it firmly, and unscrew it anti-clockwise.
If it is a square glass cover in the side, then it may be held in place with a screw or spring clip.
Hope this helps.

unscrew cover glass to gain access to bulb it unscrews normal thread very easy if glass stiff heat up oven for a few minutes and try again

The nut is a left hand thread, so unscrew it clockwise to release it, hold fan blade as you are doing this. Tighten anti- clockwise.
Plz rate my solution.
Thanks.

Unscrew glass cover anti-clockise, likewise unscrew bulb, and replace.

You don't need to slide the oven out, just remove the glass covers with a flat bladed screwdriver and then unscrew the old bulbs. Replacement is the opposite.
Bulbs available from Homebase, Wickes, BandQ etc etc.
