Hi all belling range 444444090 cooker and clock works,induction hob dead as a dodo. Says she heard a bang,no tripping of fuse box, hob went off. Had a Quick Look,but to get anywhere it needs to be taken out of a very tight space,any ideas? Or wiring diagram might be helpful. Do they have a separate power board? All rings dead and no display. Thank you in advance.
dont know the system but
I know on Zanussi hobs one of the boards supplies power to the display.; if that board fails it all goes off. if the other one fails only 2 rings fail
bet its something like that
Dave
on Zanussi its the left one
but cant say for belling
on zanussi you can plug the power lead in the other board but all the knobs cross over too. so left front is now right front
have done that while i am waiting for the board. there maybe a jumper too,cant remember
no idea how belling do it or which boards they use
also be aware some hobs need programming. where you have to link the boards and the panel. normally by a sequence you do on the control knobs
again no idea of belling
Dave
Looking at the parts list it looks like it is an EGO based induction unit with only 3 power modules (left hand 2 ring, centre 1 ring and right hand 2 ring), this being the case then the wiring diagram is pretty simple:
- All power boards recieve their own live and neutral direct from the main terminal block
- The power and display boards are daisy chained together by a 4 wire Lin bus cable (+12VDC, +5VDC, LIN (Data), 0VDC)
- The display board will connect to another small board that then interconnects to the controls.
- The LIN bus is only powered from one module (from memory its the left hand power module) and you can’t change which module powers it.
Assuming that I have remembered correctly which module powers the LIN bus then you will need to replace the Left hand Induction module.
Now as the module seems to be out of stock with most suppliers here is another option if you don’t mind a little soldering, you will potentially need:
- GBJ2510 Bridge Rectifier x 1 (ASWO #9427593)
- Not sure which of these part no’s is fitted but: H30SR5 IGBT (ASWO #Q513643) or RJH60F7 IGBT (ASWO #H326604) x 2
- 16A SMD fuse (you could just bridge the blown tracks but as they were designed as fusible links I like to solder surface mount fuses over the break – ASWO #X797682) x 4
- Heatsink Compound
The clips that hold the IGBTs and rectifer can be carefully prised off the heatsink with a screwdriver, to refit them place the heat sink on something solid then put the clip in position on top and lightly tap on with a hammer.
Before powering it up double check that there is no short circuit between any of the pins of the IGBTs or Bidge rectifier as if there is then there is another fault.Hope that helps
