So, what does the C-21 error code mean? And how do you clear error codes on a Samsung oven?

What does C-21 mean on a Samsung stove?

The error code C-21 means that the oven is overheating. It shows up on the LED screen when the appliance detects that the temperature is higher than the set temperature.

It occurs due to a few reasons, like a failed Samsung oven temperature sensor, malfunctioning thermostat, or a failed cooling compartment. Alternatively, the relay may be stuck on the board, powering the elements. Note that running an overheated oven for a long time is hazardous. It can ignite and cause a fire.

If you notice that your oven’s temperature is too high, do not open the door. Instead, you should unplug it from the power source and wait for it to cool down.

An overheating oven can also damage different compartments inside it. The parts that can be damaged include the thermostat, thermal insulation, and light bulb. As a result, the repair costs will be higher than the original.

How to fix the C-21 error code on a Samsung oven

Follow these steps to fix the error code C-21 on a Samsung oven:

1. Restart the oven

Like other electrical appliances, the best solution to an overheating oven is to restart it.

To reset a Samsung oven, switch it off by pressing the OFF button and restarting it. If the error code persists, you can reset it five or six times until it clears off.

If the error code persists, unplug it from the power source and let it rest for at least five minutes. Then, connect it to the power and switch it on. If the error code is still displayed, consult a repair technician or Samsung support to diagnose the problem.

2. Faulty temperature sensor

The main cause of the error code C-21 is a defective temperature sensor. This is a metal probe is located inside the oven, usually adjacent to the broil element. The temperature sensor’s role is to check the oven’s internal temperature and send signals to the main control board.

The control board, in turn, adjusts the temperature to the preferred temperature. Therefore, when the temperature sensor is defective, the oven will fail to regulate its temperature and hence cause overheating.

It may also detect lower temperatures than usual, causing the heating element to stay longer in the oven. This issue can also cause actual overheating and damage to the oven elements.

To solve this, unplug the oven from the power supply and let it cool for a few minutes. Next, use a multimeter to inspect the oven’s temperature sensor. If it is damaged, consult a professional technician to fix it.

3. Damaged cooling fan

The oven has a cooling fan that cools down the oven when it is too hot. A defective cooling fan causes the oven to overheat and displays the error code C-21. You can check whether the fan is properly functioning by running the oven for approximately two minutes.

If the fan does not move, consult a repair technician to fix the problem. Unfortunately, it must be replaced with a new one to resume normal operations. An electric cooling fan can be purchased in any hardware store if you want to fix it yourself.

4. Blocked oven vents

Air vents at the back of the oven regulate air circulation in the electric appliance. The airflow allows the hot air to flow out of the oven and replace it with cool air. When the oven vents are covered with dirt or aluminum foil, it may cause the oven to overheat.

Ensure that the oven is approximately 1.5 meters away from the wall. It would be best if you also cleaned off the dirt and grease in the air vents to ensure proper air circulation.

5. Defective heating element

Your oven may display the error code C-21 because of a failed heating element. Its function is to generate heat that cooks the meals.

A faulty heating element produces more heat than necessary and this causes overheating. You need to use a multimeter device to diagnose the condition of the heating element. If it is damaged, you should immediately replace it with a new one.

6. Defective thermostat

The function of a thermostat in a Samsung oven is to regulate oven temperatures for normal functioning. However, it may be defective because it is worn out or burnt. If so, it needs to be immediately replaced by a repair technician to clear out the error code.

The bottom line

The Samsung double oven error code C-21 means that the oven is overheating and requires special attention. In addition, there may be a problem with the cooling fan, thermostat, or heating element, which all need immediate replacement.

If you have tried all the above fixing techniques, you should consult a professional technician or Samsung customer support to diagnose and fix the problem.

• If not, you should find a way to open the door and replace the door latch manually. You will need a strong tool, for example, a cotter pin puller or Allen wrench. 
• Tug the door latch assembly from right to left and slide it down between the door and the top of the oven frame. The door will eventually open after several attempts.
• You can then remove the panel holding down the door latch assembly and replace it with a new one.

If you have tried all the methods above and the door is still locked, you should contact a repair technician to service your Frigidaire oven door.

Conclusion

Issues such as a Frigidaire oven door that is locked or flashes DR-0 can be frustrating. The problem can be easy to fix by simply switching the oven off to diagnose the error from a faulty door latch, EOC, or light switch.

As a result, its malfunction comes with a lot of inconveniences. Especially when you consider the high usage rate of microwaves in homes and offices.

In this article, we want to look at possible reasons your Whirlpool microwave screen is not working and how to troubleshoot the issues.

What you should do when your Whirlpool microwave is not working

When your microwave isn’t working, follow these troubleshooting tips:

1. Check the microwave door

Is the microwave door fully closed? Make sure the latch is not blocked and there is nothing preventing the microwave from closing since this could affect the display.

You should also know that the microwave cannot perform any cooking function if the microwave door has been closed for 5 minutes or more.

You’ll see the word “door” on the display. You must open and close the door for the microwave to work. This is to prevent unintentionally operating the microwave.

Solution: Make sure there is nothing preventing the door from closing. Be it an oversized dish/plate or out-of-place cooking rack.

2. Inspect the power supply

The reason your Whirlpool microwave display is off could be as simple as being unplugged from the power supply, a circuit breaker trip, or faulty wiring.

Start by inspecting the connection to the power outlet. Ensure it is not loose. Next, connect another electrical appliance to the outlet to be sure it’s still operational.

Also, check the plug and cable for signs of damage then verify the status of your circuit breaker.

Solutions: Plug the cable properly into the power outlet. But if it’s damaged replace it immediately. If the power outlet is not operational, get a technician to fix the wiring and other underlying issues. Lastly, reset the circuit breaker by switching it off then back on and replace the fuse if it’s blown.

3. Check the main control board

If your Whirlpool microwave display problems are yet to be solved, then you need to look into the main control board for faults. This is like the brain of the microwave. It sends input signals that determine what the microwave does and for how long.

So, when you have loose wires, faulty capacitors, or missing solder inside the control board, they affect the display—among other functions. You can confirm the exact problem by opening the panel and inspecting the different parts.

Follow the user manual to make your work easy and avoid costly mistakes. Better still, hire a qualified technician.

Solutions: First, if you can open the panel safely, tighten the loose wires. Next, replace the faulty parts or the entire control panel.

NOTE: Always unplug the microwave from the power outlet before you open the main control board. However, you should know that capacitors could still have some voltage that must be discharged manually to avoid electrical shocks.

4. Check the temperature and monitor fuse

When the temperature and monitor fuses are blown, the display cloud stop working. Check your manual for the location of the fuses. Once you locate them, uninstall and inspect the thin wire inside. If it is brown, then the fuse might be blown.

Solution: Look for new fuses and replace the blown ones.

6. Buy a replacement microwave

The last resort when your Whirlpool microwave screen is not working is to purchase a new microwave.

It could be the cheaper, stress-free option when you consider the cost of repairs and replacements, and the time needed to get the job done
