Samsung Oven Not Self-Cleaning

Is the self-cleaning function on your Samsung oven not working?

Then this guide is for you.

Samsung home appliances have a good reputation with consumers and pretty good ratings from most of the major review sites; however, sometimes problems can occur with their products, and they will need to be repaired.

Please follow our step-by-step guide below, and hopefully you’ll be able to diagnose the issue that is causing the self-cleaning function to fail and get it fixed up.

This guide covers the following Samsung oven models:

Check the Door Lock Motor and Switch Assembly

If you’re reading this guide, then you’ve probably tried all of the obvious ways to get the self-cleaning cycle going. So, assuming they haven’t fixed the problem, you’re going to have to look into some more technical issues that might be stopping the oven from self-cleaning.

If your Samsung oven is not self-cleaning, the first thing to check is the door lock motor and switch assembly. When the oven is going through the self-cleaning cycle, the door lock switch activates the door lock motor and switch assembly to keep the oven door from opening. When it stops working, it can prevent the self-cleaning function from starting. You can check the door lock motor and switch assembly by:

1. Turning the oven off at the wall and removing the cord from the power plug.
2. Locate the door lock motor and switch assembly at the back of the oven. You’ll have to remove the back panel.
3. Check to see if it is working; test the micro switches inside the lock for continuity by using a multimeter.
4. If you find that it has continuity, it is fine, and if not, it will need to be replaced.

Replace the Door Switch

When the door switch doesn’t work, the door won’t be able to lock and the self-cleaning cycle cannot start. Here’s how to check if you have a defective door switch:

1. Make sure that the oven is switched off at the wall.
2. Use your multimeter to test the door switch for continuity.
3. If you find that the door switch does not have continuity, it will need to be replaced. If it does, however, have continuity, then it should be working fine.

Temperature Control Thermostat

Another component to check is the oven thermostat. The role of the thermostat is to send voltage to the heating circuit and to regulate the temperature of the oven during a self-cleaning cycle. Sometimes (but not often) the thermostat might be working correctly for baking and broiling functions but not during the self-cleaning cycle.

Unfortunately, the thermostat is very difficult to test, so if you believe that it is faulty, you’ll need to replace it and then see if this fixes the problem with the self-cleaning mode.

Check the Thermal Fuse

If your Samsung oven is not self-cleaning, then it could be because of a faulty thermal fuse. The thermal fuse functions as a safety feature to stop the oven from overheating. When the oven gets too hot, the thermal fuse will trip and shut off all power to the oven. It is also possible for it to trip prematurely, which will stop the cleaning cycle from completing. If you have a blown thermal fuse, then it will need to be replaced, as it is not resettable. To check your thermal fuse, you need to:

1. Make sure the oven is turned off at the wall.
2. Use a multimeter to test the fuse for continuity.
3. If the test shows that the thermal fuse does not have continuity, it will need to be replaced.

Check the Elements

The cleaning function requires the elements to heat up enough so that the cleaning cycle can begin or be completed. Here’s how to check the elements:

1. Turn your oven off at the wall.
2. Check the elements for any signs of breaks, cracks, or blistering. If you find any visible signs of damage, then the element will need to be replaced.
3. If there is no damage, you then need to check the element for continuity by using a multimeter.
4. If you find that it has continuity, then it is fine, but if it doesn’t, it will need to be replaced.

Check the Oven Control Board

The final component to check to see what is causing your oven’s self-cleaning function not to work is the oven control board. The purpose of the oven control board is to send voltage to the bake and broil circuits. If the control board is defective, it may not send voltage to the heating components, and this will cause your oven’s self-clean function to not start. Here’s how to check the oven control board:

1. Turn your oven off at the wall.
2. Locate and remove the oven control board.
3. Inspect it for any visible signs of burnt out or shorted out components.
4. If you find any obvious damage, you should replace it straight away.
5. Even if you don’t find any visible signs of damage, you should consider replacing the control board if all other causes have been tested and found to not be the problem.
