Excessive heat escapes at top of stoves 600g oven

You may need to open the door and adjust the hinges that are attached the door itself as well as the ones connected to your stove..

The heat from your vent should be a little lower than what the oven is set at. So I doubt if you have a problem but you might want to take some temperature measurements to see.

Normally the 720ef is the oven, the hob is a separate unit and in my case is a STOVES 600G gas unit. Your unit may have a built on hob but the handbook for the 720ef does not detail this. In my case the hob ID is on the lower right hand side of the unit.
I think you will find that the elements may have failed but you will need to identify the hob to ensure correct replacements. Normally the element rating is on the base of the element. The handbook will tell you how to take the thing to pieces. It is possible that the hob element controls have failed but unlikely for all three or it may be a combination of both parts. I think you may have to contact an electrician to test everything to sort this out.

If you could provide some more information, then I may be able to help. What part of the oven is causing the problem, i.e. top or bottom door. If the doors don't shut properly then this may cause the hot air to escape. If it is one of the doors, is it sitting square in the frame?

over the range should be installed
they are desined to take the heat being over the stove will generate
as well as become your vent for the stove top

In general lets be clear. The OVEN pilot is located under the oven door at the top of the Broiler.It is a small piece of metal just before the GAS safety Valve which acts on temperature so gas won't flow unless Pilot is lit,That's the OVEN PILOT.The stove's RANGE is the top burners where you heat Pots and Pans.It has either 2 Pilot lights that connect the burners to the Flame they are under the Range Top.Newer Models use electronic ignitions no flame.Please note if you had your stove/oven disconected or Gas off when you turn it back on there will be air in the line that needs to escape before you light.This is why in NYC when Utility Co.works on steet main the MUST re-light your appliances.Be Careful with Gas.Good Luck.

You will probably have to replace the oven door hinges.
This should solve the problem
