2003 Duramax no start when hot

The oven does not come on anymore.

Your oven doesn't come on anymore? In the following we will explain to you why your oven has stopped working. There can be various reasons for this, which we will describe here.

The following causes can be considered for this malfunction:

Security advice:
Before you start troubleshooting, disconnect your device from the power supply by pulling out the plug.
There is a risk of electric shock.

The power supply has failed

Check that your electricity meter is OK and that the oven's socket is receiving power (e.g. with the help of a multimeter). Also, make sure that the socket has not melted due to overheating. If you have luster terminals, check that the electrical wires are securely connected and in good condition.

The oven lamp is defective

It looks like the oven is out of order, although in fact only the light bulb is defective. We recommend checking the light bulb on your oven and replacing it if necessary.

The demo mode has been activated

The demo mode is suitable for exhibition devices that are exhibited in specialist shops. There are times when you accidentally activated this function while cleaning the control panel. If this is the case, please refer to the manufacturer's user manual for instructions on how to deactivate this mode.

The child lock has been triggered

Most ovens these days are equipped with child safety locks. You can use this safety device to lock the buttons on the control panel and prevent the appliance from operating. You only need to deactivate the childproof lock to be able to use the oven normally again. Switching the child safety device on and off differs from one oven to another. You can find more information in the operating instructions.

The timer was switched on

The time switch can be electronic or mechanical and serves the purpose of displaying the time and executing time-shifted programs. If the clock flashes or if the timer is set to the start time, automatic position or "0", it is possible that the oven cannot be switched on. Refer to the instruction manual for your oven under “Setting the clock”.

The electrical terminal block has come loose

The electrical terminal strip is located in the back of the oven. The device's outer power cord is connected to it. If the cable has come loose or has melted into one of the connectors, your oven will not work. In this case the terminal strip must be replaced.

The door lock is damaged

The purpose of the door lock is to lock the door during pyrolysis and indicate whether the door is open or closed. If the bolt is bent, broken or incorrectly positioned and does not touch the door when it is closed, the appliance will not be able to heat. You can easily check the condition of the locking pin. It is usually located behind the control panel of the oven.

The safety thermostat is defective

The safety thermostat prevents the oven from overheating. When it is triggered, the oven no longer heats up. The safety thermostat can trip for several reasons if the cooling fan, thermostat or temperature sensor are defective. Some safety thermostats can be reset by pressing a button on the underside. You can also use a multimeter to make sure that the thermostat has continuity. If this is not the case, you will have to replace it.

The program selector switch is defective

The changeover switch, also known as the program selector switch, enables the heating resistors to be supplied with power. It can sometimes happen that the electrical contacts are damaged and no longer allow the current to pass. This part is located behind the rotary knob for the program selection. The defect can often be seen with the naked eye (one of the contacts is permanently "stuck" on the switch). You can also use a multimeter to check that all contacts have continuity when they are operated.

Buy a switch for the oven

The control board is defective

All functions of your oven are controlled with the control board (air circulation motor, heating resistors, etc.). If all the parts listed above have been checked and the circuit board is supplied with a voltage of 230 volts, then it probably needs to be replaced. You can replace them yourself or contact a licensed professional.
