Microwave ovens seem simple enough. You put food or a beverage in, push a few buttons and it cooks or heats your item. Today, microwave ovens are even smarter with one-touch cooking, delayed timers, and temperature controls. They also have error codes that can be hard to deal with. 

The Samsung microwave e24 error code may occasionally pop up. It is one of three error codes that deal with temperature control. This particular code means the microwave got too hot. Usually, letting it cool down before using it again will resolve the problem. 

Read further to decide if you need to take your microwave in for repair or call the Samsung Support Center. 

The Three Temperature Error Codes

Samsung microwaves have three error codes that deal with temperature. They are:

  • e0A
  • e09
  • e24

All three essentially mean the same thing in that they all reference the microwave oven being too hot. However, they occur at different times for different reasons. 

The e09 error comes on in some models if the internal temperature is consistently more than 320 degrees. The e24 and e0A errors show up if the oven reaches an internal temperature of more than 350 degrees. 

The solution in all three cases is to turn the oven off and let it cool. Then, when it has properly cooled down, try the operation again and see if the error continues showing up. 

Other Temperature Problems

There could be other temperature issues beyond these areas.  Microwave ovens that don’t have internal temperatures regularly over 320 degrees or reaching more than 350 degrees could have issues with the temperature sensor connectivity. 

In that case, the temperature sensor should be reconnected properly. You may also need to check the heater drive. It may need repair. If the connectively is normal, it could be an S/W error. 

You should reset the microwave to see if it continues. If it continues to malfunction, you will need a service repair tech to replace the PCB, also called the control board. After that, it should function properly. 

The Standard Fix

Samsung offers the same protocol for those with their microwave ovens that show any error. The company says the first thing to do is to unplug the microwave or flip the circuit breaker to cut off power. 

Wait at least a minute and then plug it back in or turn the circuit breaker back on. The company directs consumers to contact the Support Center if the error persists.

Another Explanation

One of the ongoing issues that relate to all error codes for a Samsung microwave is moisture. Moisture collecting in a microwave is possible from steam and other food items. Sometimes the moisture can cause a microwave to overheat or not function properly. 

You can check to see if moisture may be the problem by looking inside to see if there is condensation on the interior walls. You can check around the microwave to see if there is moisture on the outside, particularly in the back, or surrounding it. 

Take a dry rag and wipe any moisture from the inside and around the microwave. Leave the door open and let it air out for a few hours. Then try it again to see if that fixes your problem. 

Does the Samsung microwave have a fuse?

Samsung microwaves have a thermal fuse. It halts power when the appliance overheats. The thermal fuse can’t be reset or corrected if it’s bad. It must be replaced.

Why would a microwave fuse blow out?

Some fuses will blow if there is a sudden surge in electricity. This is why it still pays to unplug everything when the power goes out or during a heavy thunderstorm. 

An electrical surge will cause the fuse to short circuit. However, it’s a different cause if the fuse goes out when you first try to use the microwave. In that case, the high-voltage capacitor likely short-circuited. 

It will need replacing and you will probably need a service repair for that.

How do I know if the fuse in my microwave is blown?

You will need to use a meter to test the fuse to see for sure if it’s blown. However, that presents two problems. First, the fuse is hard to find. Second, you must empty the capacitor before doing any testing. 

Once you do the test with a meter, you will see if you have continuity. A needle that doesn’t move means the fuse has failed.

Why does my microwave keep blowing fuses?

The reason a microwave will continually blow fuses is that they are either the wrong part or they were improperly installed. 

Another reason for repeated blown fuses is other parts, like the door switch or the magnetron, were the wrong parts or improperly installed.

Why does my microwave keep tripping the breaker?

A microwave, or any appliance, will trip a breaker if it requires more electricity than that breaker circuit can handle. 

The circuit is designed to handle a certain amount of amps, or electrical current. When an appliance or group of appliances demands more current, the breaker will automatically cut off.

Should my microwave be on its own breaker?

A microwave doesn’t have to have its own breaker unless it is built into the cabinetry. Regulations in the National Electrical Code state that a circuit must be established for all fixed equipment. That classification includes things like a built-in oven or microwaves.

However, small and countertop models don’t use as much power so they aren’t required to have a dedicated circuit.

My Microwave Won’t Heat

There could be a couple of easy explanations for a Samsung microwave that isn’t heating. First, check to make sure the appliance isn’t in Demo mode, and then check the kitchen timer feature. Sometimes, heating can be affected if that is incorrect. 

Next, look at the door to make sure it’s functioning properly. Doors have safety features that trigger heat and use and the microwave won’t work if the door isn’t functional. Also, look at the vents and around them to make sure there isn’t an obstruction. 

An obstructed vent can stop the microwave from working. All you need to do is clean the area and remove the obstruction.

Call the Support Center if none of those solutions fixes the problem.

When Should I Call for a Repair?

Most Samsung microwaves won’t need a service repair person to fix any problems. That’s because most error codes can be remedied by clearing the errors and resetting the appliance. 

Other error codes can be remedied by removing moisture and letting the appliance dry before using it again. 

The time to call the Support Center or repair shop is if your microwave is consistently giving errors or the same error. That could mean a diode or the control panel is bad and need to be replaced. 

These are things that you can’t do as a DIY project since the capacitor needs to be emptied before attempting to test inner parts.

Are Microwaves Worth Repairing?

It depends on how old it is. A new microwave is worth repairing but is probably under warranty. It is worth seeing if the warranty covers the problem going on before you ditch it for a new microwave. 

Older microwaves may not be worth repairing because they are easy and affordable to buy. You must weigh the cost of repair against the price of buying a new one. 

If the repair cost is less than the cost of purchasing a new one and you can still get good life out of it, get it repaired.

How to Reset to Clear Error?

Resetting to clean an error on a Samsung microwave is easy. Just unplug it from the wall and let it sit for more than a minute before plugging it back in. The error should clear and the microwave should be reset for use.
