we are looking after a friends place with one of these safe's in them, my daughter has pushed buttons and it wont stop beeping, we dont know the code or anything?? how do i stop it beeping??

Oven keeps beeping:
As there is no reprogramming of most control boards try this, disconnect the power and wait 30 seconds and then reconnecting the power.

If it's an "F1" fault code this generally implies an electronic oven control (EOC) failure. Disconnect the power, wait 30 seconds or longer and then reapply power. If "F1" returns upon power-up, replace the electronic oven control.
The oven control can be accessed and replaced from the rear of the control panel.

NOTE:Disconnect the power cord from the power source before removing the panel from behind the console.
If its an F2 ERROR CODE, The F2 error indicates an open circuit in the oven temperature probe.

if Your range has a resettable thermostat in series with the oven temperature probe. If this thermostat opens the clock will display F2 and the oven won't heat.
You can reset the thermostat by pushing in the reset button on top of the thermostat.
Some ovens have an alarm that will beep continuously every six seconds to alert you that the oven is still on. Usually, a kitchen timer that you have set will cause the beeping, but occasionally it can be an error with the oven's settings. If it is the kitchen timer, you can simply push the "Kitchen Timer On/Off" button to end the continuous beeping. If that does not stop the beeping, it is probably beeping due to an error. You can turn the continuous beeping off but you may still need to troubleshoot the issue that is causing the beeping noise.
