I have had 3 engineers out to try and fix my stoves 720gra cooker and has changed all the printed circuit boards ,and all other parts but still the top oven and grill doesnt work and has now been classed as unrepairble by the insurance company but have you got any ideas on this problem. the grill doesnt light and internal lights come on and then go off but no ignition and the top oven sparks once but thats it.the bottom oven works ok

ignition probably serves both, if clicking when not lighting, fault or sticking button

Bad printed circuit board.

The fan timer printed circuit board controls the cooling fan and there is also a resistor on the terminal block of the cooling fan. One or both of these could be suspect. If the fan still runs, then the resistor hasn't gone open circuit and is still providing continuity. The only way to prove out the circuit board would be to change it, but that could be expensive especially if it doesn't cure the problem.

you solved this problem / replace the display . it should correct problem .. ..mm

grill switch will not turn on grill

good day,
hope this link below will solve your problem.

To take off the front button panel.
First power off the cooker, then remove the three right control knobs - they are just push on and push off. There are flats on the spindles matching contours on the knobs to ensure thay go back correctly.
Lower the top oven/grill front. Under the front button panel there are three screws going upwards. One at each end and one in the middle. Remembering how they are installed, remove them. The panel will now be loose but it is held in postion by two or three lugs which are along the top inside edge of the panel. They, from what I remember, hook into the inner panels of the cooker. I think you have to lift the lower edge of the panel towards you, to overcome the upward bend of the lugs.
The buttons for the clock are purely push fit and if you want they can be removed using a thin bladed knife.
I have to say that if you want complete access to the clock, I think you will have to take out the complete oven from the unit and take the top off, so be warned. Instructions of how the cooker is mounted are in the instruction manual.
Putting the front panel back I found to be fiddily - ensuring the lugs are located correctly, especially the one by the clock doesn't always want to work. In the end I left that one not positioned correctly, so in effect the front panel is slightly out at the left hand end.
Best of luck!

This is a solution - of sorts - but probably not the one that you were hoping for.

My Stoves 720EF oven developed the same fault.

I tried pressing the buttons in various combinations and I tried switching the power off and on, restting the timer and the clock, no joy.

I then tried getting hold of a copy of the manual and trying to fix it, no joy. Called up Stoves and booked a visit from a specialist service engineer, costing £75 +VAT for the call out, and was advised that the engineer would attempt to repair it but it might need a replacement circuit board, costing a further £110 plus VAT.

engineer arrived on the appointed day and was straight onto swapping out the circuit board - not much scope for "attempt to repair" - so that was about £190 plus VAT to fix it. job took about 25 mins and didnt seem to need anything beyond what any electrician (or electrically-expert DIYer) could do.

comes with a 12 month warranty - hopefully it will work without any issues !

If you have a regular electrician you might prefer to buy the board and get your electrician to do the job - or do it yourself, assuming that you are suitably skilled and qualified.

hope this helps

cheers

Sometimes when I clean my cooker, and it gets damp, mine ignites like that. It soon stops after it dries out. Give it chance and see.
