Is the failure of the magnetron lamp the cause of the food not being heated in the microwave oven?

Failure of the magnetron lamp, can be one of Reasons for not heating food in the microwave be considered But you need to know that the failure of the magnetron lamp and the time when it is known as the cause of the food not heating in the microwave depends on various factors:

• Sparking due to the presence of metal in the microwave
• Failure of the magnetron cooling fan
• Failure of voltage transformers
• Malfunction in the thermal fuse
• Bugs on Mica’s page

If you decide to fix this cause of food not heating in the microwave, you can follow the following steps:

• Disconnect the two plugs and the power cable of the microwave device from the power outlet.
• Check the thermal fuse.
• Make sure the health of the fan blades
• If there has been a spark in the microwave in the past few days, make sure that the magnetron lamp has not been damaged.
• Check the resistance of the screen bases.
• Do this with the help of an ohmmeter.
• The resistance should be 3 ohms.
• Check the output terminals of the magnetron lamp.

Dear users; In case of failure in the LG microwave oven and failure in this device, you can LG microwave repair in IP Emdad Contact the centers of this company.

Is failure in the electronic board the cause of the food not being heated in the microwave oven?

The electronic board works as the brain of the microwave device. Its breakdown can be as The reason for not heating the food in the microwave be For this reason, you should professionally examine the electronic board in order to solve the cause of the food not heating up in the microwave oven. But note that before trying to check this cause of food not heating in the microwave, check other common reasons.

Is the failure of the voltage transformers the cause of the food not being heated in the microwave oven?

Voltage transformers are responsible for bringing the city’s 220 voltage to 2000. Then transfer to the magnetron lamp and heat the food in the microwave. If you are looking for the reason why the food is not heated in the microwave oven, be sure to ensure the health of the voltage transformers. To repair and fix the cause of the food not heating in the microwave oven, you can do the following:

• The trans smells burnt or there are signs of burning on it.
• It is possible that the transformer makes noise or smoke.
• If you see any of the mentioned things, you should repair and replace the transformer.
• You can contact the microwave repair center to replace and repair the transformer.

Is the failure of the diode the cause of the food not being heated in the microwave oven?

Failure in the diode is one of the reasons that can be mentioned as the cause of the food not heating up in the microwave oven. If the diode is damaged or damaged in any way, the voltage transformers cannot increase the voltage for the device, therefore they are known as the cause of the food not heating in the microwave oven. To fix this The reason for not heating the food in the microwave You can follow the steps below:

• First and before doing anything, disconnect the cable and two plugs of the microwave device from the power outlet.
• The diode in the microwave structure is connected to the capacitor on one side and to the body on the other side.
• Be sure to discharge the capacitor and disconnect the diode from the circuit.
• Activate the buzzer on the multimeter and place the diode on the two pins.
• If you hear a beeping sound, it means that the diode is defective.
• In case of diode failure, you should replace it as soon as possible.
• We advise you to contact your microwave repair agency to solve the problem of food not heating up in the microwave oven.

Is the defective capacitor the cause of the food not being heated in the microwave oven?

Failure and damage of the capacitor is another reason for the food not heating up in the microwave oven. The function of the capacitor is to convert alternating current into direct current in the circuit. When the direct current enters the voltage transformer, the transformer will transfer the necessary energy to the magnetron lamp by increasing the voltage. For this reason, the faulty and damaged capacitor is the cause of the food not being heated in the microwave oven. You can check the health of the capacitor through the following steps:

• Be sure to first disconnect the wire and two plugs of the device from the electrical outlet.
• Place the multimeter on the pins.
• If the multimeter beeps, don’t doubt that the problem is in the capacitor.

Is failure in the door microswitch the cause of the food not being heated in the microwave oven?

Failure of the door microswitch, on the other hand Reasons for not heating food in the microwave is. This part in the structure of the microwave device is responsible for issuing the command to close the door to the electronic board and causing the process to start and the device to work. If you want to investigate the reason why the food is not heated in the microwave oven, be sure to be sure of the safety of the microswitch on the door of the device. If the cause of the food not heating up in the microwave is the failure of the microswitch, you should change it as soon as possible.
