Samsung Uncommanded Operation / Control Failure

Oven interior light and fan turn on by themselves or the oven starts heating without input.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Shorted touch panel, Stuck relay on PCB, Moisture in control panel, Firmware or logic failure

Safety first: Turn off power at the breaker immediately. Do not leave the oven connected if it turns on by itself.

Dry and inspect:
- If this occurred after heavy steam or cleaning, allow the control area to dry fully.
Inspect touch panel:
- Check for signs of moisture or corrosion; replace if damaged.
Inspect PCB relays:
- Look for welded heater or light relays; replace the main PCB if found.
Because this is a safety-critical issue, professional diagnosis and repair are strongly recommended.
