Imperial oven will light but will go off when you turn on more than two Cooker burners. What could be the cause ?

SOURCE: our imperial convection oven will not light. NO ignition

Your door switch is not reading that the unit is closed

Is this gas or electric? If it is electric, you will want to test the power to the burners with a voltmeter. This will tell you if the control is bad and not giving power to the burner, or if the burners themselves are bad or possibly just loose or corroded connections.
If you have gas, check the gas valve and the tubing. Make sure there are no holes or gaps letting out the gas, make sure the valves is completely up to allow full gas flow. Also check that the tubing is clean of debris.

There is a fault on your plate sensor (the rod crossing through the center of the plate). You should be able to get a replacement if not you can replace the plate, but my advice is just ignore it. Its only there to make you aware that the surface is still hot during and after use.

Hello,

Since basically nothing works,nither oven nor the surface burners, the first thing ya should be checking is for a burnt or broken wire connection on the back where the cord connects to the house wiring also need to check for a bad circuit breaker its possible for the breaker to appear to be on yet be burnt out internally....of course i would reccomend that if the wires on the back aren't burnt that ya call a electriction and not go inside of your breaker panel since it could be very dangerous unless your confident with electric work.
