Oven Repair

It’s a hungry person’s worst nightmare! You go to turn on your Samsung oven to make your dinner, and nothing happens! This is bad enough if you’re just making food for yourself and your family, but if you’ve got guests over, it’s nothing short of disastrous! Thankfully, there are quite a few easy fixes for this problem – read on to find out what to do!

Our guide covers all major models of Samsung ovens, including: 

















Power Supply Issues

Your Samsung oven can’t operate without electricity! If there’s an issue with the power outlet or the circuit, your oven won’t be able to heat up. If this is the case, your oven won’t just fail to heat up – it won’t display anything, not even the clock! 

To fix this:

  • First, check that the oven is turned on and the power cord is plugged into the outlet. 
  • Go to your home’s circuit board and check to see if the circuit breaker that corresponds to the oven has tripped. On most circuit boards, the breaker for the oven is clearly labeled. 
  • If the oven circuit breaker has tripped, reset it. 
  • Turn your oven on again, and check to see if it is now heating up. If this doesn’t fix your issue, move on to our next step!

Faulty Thermostat

The thermostat is in charge of controlling the oven’s internal temperature. If the thermostat is faulty, your oven may either not heat at all, or it may heat to the incorrect temperature. Try using an oven thermometer that you place inside the oven to see what the actual temperature inside the oven is, then compare it against the set temperature. 

To fix:

  • Check to see if the thermostat is clicking off. If it is clicking off as if it has reached the correct temperature, but your thermometer has shown this is incorrect, your thermostat may need recalibrating. 
  • Take your Samsung oven user’s manual and follow the steps inside to recalibrate the thermometer.
  • If the thermostat appears not to be responding at all, it will need to be replaced. Order a replacement thermostat that is compatible with your model Samsung oven, and follow the plan in your manual to replace it. 
  • Once the new thermostat is installed, check to see if the oven is now heating up properly.

Faulty Heating Elements

An oven has two elements – the bake and broil elements. The bake element is at the bottom of the oven, while the broil element is at the top. These elements glow red when they’re working, but if one or both are faulty, it will impact the oven’s heating capacity. 

To check if there’s an issue, turn the oven on and check to ensure heat is coming from both elements. They should both radiate heat and glow red evenly. Check to make sure that they are heating evenly – it’s possible for one side to be faulty, which leads to uneven heating. 

To fix

  • Visually inspect the elements for damage. If either element appears damaged in any way, or if part of the element is not heating up, you’ll need to replace it. 
  • Order replacement heating elements that fit your oven, then install the new elements in place, making sure they’re wired correctly. 
  • Once the elements are installed, turn your oven back on and check to see if it’s heating up properly. 

Malfunctioning Temperature Sensor

The temperature sensor is located on the interior of the oven. It’s a long, thin probe that is usually a few inches long. It’s designed to sense the interior temperature of the oven and transmit this information to the thermostat so that the thermostat can adjust the temperature accordingly. The temperature sensor is attached to a wiring harness, which links it to the oven control system.

You can find the temperature sensor inside your Samsung oven cavity, usually at the top left or top right-hand corner. 

If the temperature sensor becomes dirty or damaged, it can lead to malfunctioning, which can mean that the oven doesn’t heat up properly.

To fix this:

  • Sometimes, the temperature sensor can get a buildup of grease, grime, and food particles. This can interfere with its ability to sense temperature. To fix this, turn off the oven and thoroughly clean the sensor. If the grime won’t easily wipe off, try coating the sensor in a paste of baking soda and water and leaving it to sit, then wipe it away. 
  • If the sensor is bent, broken, or otherwise damaged in appearance, it won’t be working properly and will need replacing. If you’re unsure if your sensor is working, test it with a multimeter to see if it shows continuity. If it doesn’t, it will need replacing. 
  • Order a replacement temperature sensor online, ensuring it is compatible with your particular model of Samsung oven.
  • After ensuring the oven is disconnected from the power supply, remove the old sensor, including removing it from its wiring harness. We recommend taking a picture of the wiring setup with your phone so you can easily connect the new sensor in the same manner.
  • Put the new sensor in place, connecting it to the wires. 
  • Restore power to the oven and turn it on, checking to see if it is now heating up to the correct temperature.
