my father's Neff D2615 XOGB/01FD8205 001739 F5750 311-297 cooker hood, ie fan and light stopped working after a bang. there is 240v through switches to light bulb centre contact (which blew and has been replaced with a new 60w bulb, )when i earth test probe on a mounting screw, but with probes on centre and earth cotact there is no power suggesting to me a problem with the earthing as both light and fan wires appear to earth on the same terminal of a module to the right of the rocker switch panel . Fan rotates freely by hand, so can there be a problem with the module which earthes both fan and light as new bulb tests okay ?
Hi Michael, yes thats what i would like to do, hopefully i have rated service excellent, is further testing required ? i do have part diagram emailed from Neff this morning.
are you able to continue with this fault please ?
thanks , Ransomes spares closed until 9am tomorrow, but just phoned Neff and all they show is the actual rocker switch assembly for £26 which is cheap enough ,but is that what you mean by a main control board ? i could see some sort of small terminal block behind the casing to the right of the switch panel which took a ground wire from the bulb holder and also the fan.
just back from work, yes there was power to the switch and from the switch when turned on, i rang Ransomes today, and the terminal block which I mentioned to the right of the switch panel , they identified as a 3pole terminal clamp , part no. 00030986 which they say is a white block which tallies with what i saw, but this is no longer available !this block which takes a neutral (or ground wire ) onto 1 terminal from both the light and the fan.
not quite sure what could go wrong with this terminal clamp ?but it seems to have broken the circuit to the light and also the fan.
Hi Michael, thanks for that, by taking power from the switch, and momentarily connecting the neutral wires to a suitable earth on the casing, this would isolate the block and also test the block for continuity, by control you mean the neutral wire to the fan and the light ?
Hi Michael, sorted cooker hood at weekend, Neutral wire betweeen isolating switch and control board was broken close to terminal at isolating switch, so in the end nothing to buy just an easy fix, once fault found,
thanks for your help
