I HAVE BOUGHT A SECOND HAND STOVE ELECTRIC OVEN MODEL NO. 720EF . CAN I GET A OPERATION HAND BOOK

The handbook says:-
To cancel the automatic setting and return the oven to manual operation, press the cook time and ready time buttons simultaneously. These are the second and third buttons from the left. If you have done that and it is not working, try turning the complete oven off for awhile - say 30 mins and turning back on. If this still doesn't work then it may be that the timer/clock has gone faulty.

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

Supply an email address and you can have a copy.

I am not an expert on this but I believe the answer is NO. The burners/regulator are different.

The clock controls the ovens. In other words, directly you set any time on the clock, a contact operates within it to provide power to the ovens. (Normally the grill remains operational). You may need a new clock/timer. Before you do so, try switching the power off at the main isolating switch and leaving it off for a few mins, then switching it back on, to try to get the clock to operate. You may need to do this a few times.
Normally Stoves stick a label identifying the model on the left hand edge of the lower oven. You see this when you lower the main oven door. it will probably start with a 05 and be 9 digits long. With this number you can identify the oven and obtain parts.

If STOVES are not able to help at all, then ask them what the model number is. With that information you may be able to locate a handbook.

No, there is no reset button. However, the grill will only work when the front is down as there is a microswitch which operates to provide connectivity when it is in this position. This is to stop the grill overheating. The switch could have gone faulty.
Does the top oven work ok?
When you operate the grill there are two options, part or full. Are they both failing? Does the cooling fan switch on when either grill is operated?

The normal STOVES label is on the rear of the oven, but there should be a small label visible on the left hand side of the lower oven when you lower the door. There should be a long product number on that with the unit serial number. The product no can be used to identify the unit. STOVES may be able to help here.
I have a 720EF handbook scanned and it is on my BT Digital Vault, so if you want this version give me a valid email address and I will ensure you receive a copy.

could I please have a user manual for a EFA 700H. Thanks

I have the Stoves 720EF manual stored on the BT Digital Vault which might help. If you want a copy of it, supply an email address and I will give it access.
Also someone else has said that if you speak to Stoves nicely they may be able to send an electronic version of the manual instead of the paper copy.
