What if Galanz microwave oven is not heated?
The reasons why Galanz microwave oven is not hot may be: the fuse is broken, the temperature sensor fails, the high-voltage line is close to the shell, the low-voltage fault and the high-voltage fault. I will introduce in detail how Galanz microwave oven is not hot.
What if Galanz microwave oven can't be heated? 1. High voltage fault
The high voltage fault of Galanz microwave oven is generally caused by three components, high voltage diode, magnetron and high voltage transformer. Due to the different working hours of the microwave oven, the damage probability of the three components is also different. Galanz microwave ovens are mostly not heated because of the short circuit of high voltage diodes. According to the time, the proportion of short circuit caused by diode failure in microwave ovens within 8 years is more, and that caused by magnetron failure in microwave ovens beyond 8 years is mostly. There are several reasons why the microwave oven doesn't heat up because the high voltage transformer is damaged.
Remove the power transformer of the microwave oven, first unplug the power plug, remove the cover of the microwave oven, discharge the capacitor, remove all the leads of the primary transformer and filament, remove the mounting bolts that fix the transformer from the bottom of the chassis, then take out the transformer, reinstall a new transformer, and debug and troubleshoot.
If the microwave oven can work normally, but it can't be heated, it means that one of the magnetron, transformer, grounding bidirectional tube (high voltage diode), high voltage fuse and high voltage capacitor in the high voltage part of the microwave oven is broken. You can disassemble the shell by yourself, check whether the high-voltage safety tube of the plastic shell is burned, and replace it with a tester of the same specification, and the problem of Galanz microwave oven not heating will be solved.
If it doesn't work, the magnetron and high-voltage diode of the microwave oven are likely to be broken, and the reduction of capacitance will also lead to no heat when the furnace works (if the insulation to the ground is poor, the fuse and high-voltage diode will be burned out). It can be disassembled and inspected by itself. First, use the multimeter × × 10K high-voltage diode, and block in one direction and about 30~ 150K in the other direction (uneven). If it is a normal magnetron (the two legs of the filament × 1 can be blocked), the capacitance drop must be judged by a capacitance meter (and its insulation to the ground should be qualified), and the possibility of transformer failure.
What if Galanz microwave oven is not heated? Second, the high-voltage line is close to the casing.
During the use of the microwave oven, it was found that there was an open flame in the oven, and then the microwave oven could not be heated. It may be that the high-voltage line is close to the microwave oven shell, and the fault is eliminated after the high-voltage line is separated. In addition, heating fried food in a microwave oven will have the same consequences, so don't risk heating things with high temperature and heat in a microwave oven.
What if Galanz microwave oven is not hot? 3: The fuse is broken.
When the Galanz microwave oven is not hot, the first reaction is that the fuse is broken. Just change the fuse. If the fuse is intact and the situation is unknown, it can also be handed over to a professional maintenance master.
What if Galanz microwave oven can't be heated? 4. Low voltage fault
The low-voltage fault of Galanz microwave oven is generally due to the problem of low-voltage power supply line, resulting in that the 220V AC voltage is not sent to the high-voltage transformer or frequency conversion board, and the high-voltage part does not work, resulting in no heat. Most of the low voltage is caused by timer damage (mechanical microwave oven) or computer board relay damage (computer microwave oven), and a small number of microwave ovens are caused by microswitches.
What if Galanz microwave oven is not hot? 5. The temperature sensor is out of order.
The microwave oven does not heat, and the heated food often burns. It may be because the temperature sensor of Galanz microwave oven is broken, so the temperature sensor can be replaced.
