6 Causes Of A Samsung Oven Not Heating Up Properly

There are some common causes for Samsung oven not heating. They are mostly related to faulty components that can be diagnosed easily. You would often find this problem only after you find an uncooked meal or an unbaked cake lying inside your oven. So, you might need an immediate solution to find why this happened and how to fix it quickly. You can do it yourself by using this guide before you call a technician. But if the problems are too complicated for you to handle, you might need to get professional help from your appliance repair technician.

List of Causes for Samsung Oven Not Heating

These are the possible causes why your Samsung oven would not heat up. Follow these procedures to troubleshoot your oven correctly. Most importantly, be careful when working with electrical and heating elements.

CAUTION: Unplug all electrical appliances from power sockets before you inspect anything or troubleshoot. Do not touch the heating elements with your bare hands and never get in contact with bare wires. Make sure to wear PPEs to ensure your safety and avoid hazards and danger.

Oven Door is Open

To start this troubleshooting, check whether the oven door is closed well. If it is even slightly opened, the Samsung oven will shut off after about one minute as a safety precaution. So make sure to carefully close the door always when placing items inside, taking them out, or when preheating.

Power Supply Issues

If your Samsung oven does not get enough power to operate, then it might not heat properly. To check whether your power supply has any issues, you can check it as follows for Samsung electric range problems.

  • Ensure proper power outlet: Electric ovens need a 240V outlet for adequate power. A gas oven requires a standard voltage of 120V. Double-check the power supply of your oven.
  • Check cord and outlet for damages: Examine the power cords for tearing or damaging and replace them if necessary. Sometimes, there could be wires that might be burned near heat sources, and you can identify them. You can check the outlet by unplugging the oven and plugging in a smaller test appliance. If it doesn’t turn on, the power outlet might be faulty, and you need to get it checked by an electrician.
  • Look for tripped breakers: Check your home’s main circuit board for tripped breakers. If there are any, reset them. Even if the oven’s breaker is not tripped, turn it off and turn it back on after 30 seconds.
  • Thermal Fuse: The thermal fuse would trip off to cut the power supply in case the oven gets overheated. This might not be a regular event, and to check whether the fuse has blown out, you can use a multimeter to test for continuity. If you find an issue in this, the thermal fuse would have to be replaced as it cannot be reset.
  • Oven Control Board: The oven control board consists of relays. They send voltage signals to the circuits to function according to the sensor inputs and user settings. So a faulty control board might not send the required signals for the heating components. Before you replace the oven control board, make sure to check other possible faults in the individual components. This is because the control board cannot be repaired and needs to be replaced completely.
  • Relay Board: Some ovens have a relay board that controls the relays, which convey electrical signals to the heating element. If one or more relays fail, then you would find the Samsung oven not heating. You can get this checked by a technician, and if the relay board is faulty, then you would have to replace it.

Demo Mode On

The Demo mode might be activated if the Samsung oven is not reaching the required temperature. This mode is used for showroom purposes to display its functions without heating it. You can see that the control panel displays codes such as tESt, tE 5t, d, or DEMO when the Samsung oven is in demo mode. Use your user manual to find how this mode can be turned off. The options button would provide a list of functions that include the setting of demo mode. You can also deactivate this mode using these steps.

  • Press Options button
  • Select #6 for Demo mode settings
  • Press OK button
  • Select #2 to turn off Demo mode
  • Press OK to confirm the setting

Defective Igniter

A defective igniter might be the reason why a Samsung gas oven not heating up. The igniter gathers electrical current to open that valve which allows gas flow and generates an electrical spark to light the gas. The oven would not heat up if the igniter fails to do these tasks. You can check this by turning on the oven and checking the time it takes for the igniter to light the gas. If you find that the igniter takes more than 90 seconds to light up, then it might be defective and weak. If it does not light at all, then the igniter might need replacement.

  • Safety Valve: The gas oven safety valve works with the igniter to allow gas flow to the burner. If this valve fails to function, then the oven won’t light up or heat. This might be a rare occurrence, and you need to check the igniter before determining this as the fault. You can check the safety valve with a multimeter, and if it shows no continuity, then it needs to be replaced.
  • Valve and Pressure Regulator: There is a very low possibility for the defective valve and pressure regulator to be the cause of the oven not heating up. This is also misdiagnosed very often, and it is better to check all possible defective components before replacing this regulator.

Broken Bake Element

Samsung oven not heating might also be due to a broken baked element. You can locate this at the base of the oven, and it consists of electrical wires encased in a metal coil. Most of the heat for baking and roasting is supplied by the bake element. Food is baked with the heat emitted when the coil glows red with the electrical current supplied to the wires.

This is also one of the most common Samsung self-cleaning oven problems. The functions of the bake element would be destroyed due to the breaks and blistering caused by the very high temperatures of the self-cleaning setting. The coil might also have a spotty red glow if the element is defective. If you find connectivity issues when checked this with a multimeter, then you would have to replace this component.

Oven Thermostat Needs Calibration

Another reason for your Samsung oven not heating up might be due to needing calibration. Even though the oven is set to specific settings of temperature, the actual temperature inside the oven may vary. The thermostat is responsible for setting and regulating the internal temperature. To improve the accuracy of function, it may need to be recalibrated. You can refer to the user manual to learn how to recalibrate your specific model of oven. The process would commonly begin by selecting thermostat adjustments from the options menu. Usually, most ovens can be calibrated up to 35 ℉ for optimum accuracy.

The oven thermostat consists of a thin copper tube attached to a slightly thicker tube attached to the oven. This tube has a hydraulic fluid that expands as the broiler temperature rises. This increases pressure on a small activator inside the thermostat, which turns off the heat. When the broiler cools, the activator allows it to heat up again due to the reduced pressure. It is difficult to test the oven thermostats and needs to be replaced if defective because it is not repairable. 

Frequently Asked Questions

Why is my oven not heating up all the way?

A faulty sensor might be the cause for this, and sometimes, the sensor might even be touching the wall of the oven. If it is still not working after all troubleshooting, the temperature sensor might need to be calibrated.

Why is my Samsung oven not keeping temperature?

The problem might be in the thermostat or the heating element of the oven. These components should be checked first before troubleshooting others.

How much does it cost to replace the heating element in the oven?

Heating elements cost around $20 to $25. However, the labor cost would add up to around $220 for old element replacement.

Why does my Samsung oven say “test”?

This indicates that the oven is in demo mode, and the oven would not heat up. Turn it off as indicated in the user manual.

How many years does an oven last?
