Even 3 or 4 years ago recirculation my elder Neff cooker acknowledged their service; there was then a bang, the fuses were flying out and from then blew the fan oven only cold air in the oven. Well, I gave myself time to the still functioning upper and lower heat content, especially as my cooking is not necessarily the biggest strengths of my hand counted ... and I did not pay for expensive repairs by a technician. More by chance I came across a Google product to which the relatively simple repair was described in detail, as almost the only source of error was named a defective ring heating. With a strong Phillips screwdriver I built the rear cover in the oven off and lo and behold: a burned through ring heater (see pictures) was the source of error! So even read the stamped article number typed in spare parts country and become immediately find: the searched part was available and even extremely inexpensive ... ordered on Thursday and yesterday (Monday) was the postman at the door! Toll !!! With the installation instructions published here (thank the outpost !!), plus an additional M4 screw nut and a small 7-ner wrench was the exchange now nothing in the way ... right last night I went to work!
The small thread of self-tapping screw at the back had, as described, be a little extended; plugged the ring heater and locked from behind, plugged the cable lugs and started a trial run ... everything works wieder..freu! Now I just had the paneling of the oven behind the oven in festschrauben..fertig! The whole has lasted about 30 minutes, most of the time it took me nearly so, to fumble in the dark oven the four self-tapping screws back into their holes provided -. A screwdriver with magnetic tip makes as good phone!
My summary: the installation is relatively simple, the spare part was delivered quickly and accurately ... and instead of spending 120 euros for a technician I invest the money rather in crispy roast! And thanks again for the detailed installation guide here at the beginning of the reviews :-)
