Stoves 720 EF Electric Double Oven Model No 059040415 -when you turn the grill knob there is no light and it doesn't do anything at all - the grill is not working. However, the element must be working as the top oven does heat up when you turn that knob so is this a problem with the knob or thermostat? What part would we need?

First things first. The top oven lights ONLY come on when the top oven is switched on. Operating the grill DOES NOT turn the lights on. If you wish to see what you are grilling, you have to turn the top oven control knob on to its first position as well as turning the grill on.
Secondly, the grill only works when the door is open. The grill does not work when you shut the door. When you open and shut the door, you should be able to hear the microswitch operating. It is located in the right hand side of the cooker, between the inner and outer panels - you cannot see it. I haven't seen the switch first hand but they normally come with an arm that contacts the door mechanism and the door mechanism operating, causes the arm to move, which causes a button on the switch to move and make the circuit. It has been known for the arm on the microswitch to bend with use so it no longer works correctly.
If you have checked all above and you hear the switch operating, then it could have failed. They are quite common, so if you can't get one from STOVES, try espares or someone like Maplin or RadioSpares.
The get to the microswitch you have to take the oven out of the housing and then take the right hand panel off. You should then be able to see it and check its operation.
All the best

It looks like the clock has failed. Try leaving the power off for at least 10 mins, turn it back on at the main switch and then try it. If it still doesn't work Espares can get you a new one. Incidentally, if there is power to the oven, the grill will work even if the clock is not set.

I can send you one but I will need an email address to do so!

The unit is working as it should. The top oven lights will only come on when the top oven control knob is turned on. The grill control does NOT turn the lights on. If you want to see what you are grilling, then you should turn the top oven control on to its first position. This works even if the grill is operating.

I have a pdf version which I can send to you if you supply an email address.

Try espares. If the part is not listed, there is a contact on the website to obtain a quote for a part. Of course once you have the part number you can try elsewhere.

I have a Stoves Newhome EL716 double electric oven and last night, it just lost all power and stopped working - no grill, oven, lights, clock or anything. Can anyone tell me what this could be please? Thank you.
