First and foremost, check if your Samsung microwave is getting proper power supply. If the microwave is not receiving adequate power, it will not heat up the food. It is essential to ensure that the microwave is plugged into a functioning power outlet properly. If required, plug in another device such as a lamp into the same power outlet. If the lamp is working, then most likely, the power source is not the issue.

However, if the microwave still does not work, then try unplugging the microwave and plug it in again after a few minutes. Sometimes, the circuit breaker or fusebox that provides power to the microwave may trip. Resetting the circuit breaker or changing the fuse may be necessary to ensure if power supply is the issue.

Unplug the microwave for some time, around half an hour. It will allow the appliance to refresh and start fresh. Plug in the microwave into the power outlet and attempt to heat up food again.

If the power supply issue persists, then it is better to call the manufacturer or a qualified professional to repair the microwave. It is not recommended to open the microwave chassis or work on it if you don’t have technical knowledge. Becoming well-informed is the first step in preventing accidents and damage to the appliance.

Inspect the Internal Fuse

If your Samsung microwave isn’t heating, the internal fuse might have blown. The internal fuse is a safety device that shuts off the microwave if there is a power surge or other electrical issue.

To inspect the internal fuse:

  1. Unplug the microwave from the electrical outlet or turn off the circuit breaker that powers it.
  2. Locate the internal fuse on the inside of the microwave. The fuse is usually located near the power cord, near the place where it enters the microwave.
  3. Remove the outer cover of the microwave by unscrewing or unclipping it. Be careful not to damage any wires or components inside the microwave.
  4. Locate the fuse and remove it by gently pulling it out or unscrewing it depending on the type of fuse. Check the fuse visually to see if it is melted or burnt. If it is, then it needs to be replaced.
  5. Use a multi-meter to test the fuse. Set the meter to the “continuity” mode and touch the probes to the ends of the fuse. If there is no continuity, then the fuse is blown and needs to be replaced.
  6. Replace the fuse with a new one of the same amperage rating as the original. You can buy replacement fuses at your local hardware store or online.
  7. Reattach the microwave cover and plug the microwave back in or turn on the circuit breaker.
  8. Test the microwave to see if it heats properly.

If replacing the internal fuse doesn’t fix the problem, there may be an issue with the high voltage diode, magnetron, or other electrical component. It is recommended to contact a professional technician to diagnose and repair these issues.

In conclusion, inspecting the internal fuse is an essential step in troubleshooting a Samsung microwave that won’t heat. It is a simple and quick process that you can easily do at home. Remember always to unplug and turn off the power before attempting any repairs or inspections to avoid electrocution. Stay safe and enjoy your working microwave!

Test the High Voltage Diode

High Voltage Diode

If your Samsung microwave has been running for a long time and it doesn’t heat up, chances are that the high voltage diode is malfunctioning. High voltage diode operates by alternating the flow of current on a unidirectional path. If it is not functioning properly, it will stop the flow of electrical current that comes from the magnetron, and as a result, the oven won’t heat up. However, fixing it is quite simple.

The high-voltage diode can be tested using one of two methods: a multimeter or an ohmmeter. In this section, we will discuss the process of using an ohmmeter to test the high voltage diode in your Samsung microwave. Here are the things you’ll need:

  • An ohmmeter
  • A pair of pliers

Here are the steps that you can follow to test the high voltage diode:

  1. Turn off the circuit breaker that supplies power to your microwave
  2. Locate the high voltage diode, which can be easily found behind the magnetron
  3. Unplug the lead and connector from the high voltage diode’s terminals
  4. Set the ohmmeter to a low resistance setting
  5. Connect the ohmmeter to the terminals of the high voltage diode. Ensure that the red lead of the meter is connected to the anode side of the diode; likewise, the black lead is connected to the cathode side of the diode. Take note that the anode side of the diode refers to the side marked with a “+”, while the cathode side refers to the one that is marked with a “-“
  6. Observe the reading on the ohmmeter. If the reading is zero, it means that the high voltage diode is faulty and needs replacement. However, if the reading displayed is high, it means the diode is functioning correctly.

If the reading is zero, it implies that the high voltage diode is faulty, and you need to replace it. Samsung microwave high voltage diodes are inexpensive and readily available from online retail stores that sell Samsung microwave parts.

To replace the high voltage diode in your Samsung microwave, follow these simple steps:

  1. Remove the casing of the microwave oven to gain access to the internal components. However, this procedure differs for various models, and you might need to check your user manual for a specific guide
  2. Locate the high voltage diode and remove it gently using a pair of pliers
  3. Replace the diode and connect it back to the terminals of your Samsung microwave oven. Note that the connections on the anode and cathode are critical and should not be interchanged. You can check the markings on the diode to avoid any confusion during reassembly.
  4. Replace the microwave oven’s casing, and restore power to the microwave oven by resetting the circuit breaker.

This is how you can quickly test the high voltage diode of your Samsung microwave oven and replace it if it is faulty. Be sure to follow the instructions outlined to avoid further complications, and if you are unsure of your ability to fix the issue yourself, seek the services of a professional technician. In most cases, repairing high voltage diodes is relatively simple and straightforward.

Examine the Magnetron Tube

Magnetron Tube

If your Samsung microwave isn’t heating, the problem could very well lie with the magnetron tube. This is a critical component of your microwave that is responsible for producing the electromagnetic waves that cook your food. Here’s what you need to know about examining the magnetron tube:

The first thing you’ll need to do is unplug your microwave and remove the cabinet. You should also discharge any capacitors to avoid any electric shocks. Once you’ve gained access to the magnetron tube, inspect it closely for any signs of damage. This could include cracks, burn marks, or other physical abnormalities. Even if the magnetron tube appears to be in good condition, it could still be the source of your problem.

The next step is to test the magnetron tube for continuity. This requires a multimeter, which is a tool used for measuring electrical resistance. With the multimeter set to the resistance setting, touch one probe to the magnetron terminal and the other to the metal housing. A good magnetron tube will have a resistance reading of less than one ohm. If the reading is higher, the magnetron tube should be replaced.

Another potential issue with the magnetron tube is a faulty diode. This is a small component that is connected to the magnetron and helps to regulate the electrical current. To test the diode, disconnect it from the magnetron and use the multimeter to check for continuity. A good diode will have low resistance in one direction and high resistance in the other. If the readings are reversed or the diode has no continuity in either direction, it will need to be replaced.

Once you’ve determined that the magnetron tube is the problem, you’ll need to replace it. This is a job that should only be done by a professional, as the high voltage involved can be dangerous. It’s also important to use the correct replacement part, as using an incorrect part can lead to further problems down the line.

In conclusion, examining the magnetron tube is an important step in fixing a Samsung microwave that won’t heat. Be sure to take the necessary safety precautions and use a multimeter to test for continuity. If you’re unsure about any aspect of the process, it’s always best to seek the help of a professional technician.
