Resolved Question:

I have a neff oven B1664N0GB/01
I have just replaced the oven lamp (complete) in the top right corner of the unit. I turned it on and it initially worked fine but then when i tried it a second time something went wrong. There was a 'zap' and a spark of light which tripped the main fuse box. I reset the fuse box and the oven heats up but now the halogens and the main light no longer work. I have inspected the main bulb, which is intact and one of the halogen bulbs also looks fine.
Grateful for your advice.

Hello Manoz, my name is***** you tell me the procedure you used to replace the lamp and holder.Also, you say "one of the Halogen bulbs".. Can you tell me to which Halogen bulbs you are referring?

Hi George,there are 2 halogens near the bottom of the door which only illuminate when the oven door is closed, activated by a small switch at the top left of the door - this switch can be rotated clockwise to activate/deactivate the lights.on the neff spares website they are on page 4, part 401.i have not replaced the halogens, merely removed the cover and the bulb and inspected the bulb.

i removed the entire oven from its housing, removed the rear top cowling and then pushed the old lamp holder back down into the oven. from the inside of the oven i disconnected the 3 wires and removed the failed unit. i connected the new complete lamp unit, left it dangling inside the oven, turned the oven on and it worked fine. i turned off the oven, pushed the unit back up into its housing so it 'clicked' in. turned on the oven and everything fused.

Ok, remove the ovens top cowling and check the wires that connect to the lamp... Check that there is no chaffing of the wire that could earth to cause the fault you have. Also look for a trapped wire

ok, when i pushed the lamp holder up and in, i failed to bend the terminals back so they have popped up against the metal casing - doh!

hi George,As you suggested, the fault lay with (three) blown circuits on the controller board. I followed your instructions and repaired them by soldering pieces of wire between the connections. All the lights are working now!So today i've learnt how to solder a circuit board and also how to use a multimeter correctly. All in all a great result, i'm so very, very pleased - thanks a ton!
