Sometimes we use the microwave oven, there will be some faults, and sometimes will encounter the case of not heating, then encounter such a situation generally have what aspects of the reasons, and how we should deal with it, next we introduce the United States of America's microwave oven does not heat up what is the reason? The United States microwave oven does not heat how to do?
What is the reason that the microwave oven does not heat?
We know that through the heating of the diode our microwave oven can better control the heating of food. Then the following take a look at the United States microwave oven does not heat the reason:
1, the second door interlock switch is bad: this two door interlock switch damage is due to frequent operation, poor contact, electric shock destruction caused by the 220-volt operating voltage can not work properly. Solution: first check whether the fuse is blown, and then see whether the monitoring switch is normal, if it is normal, it means that the interlock switch is bad. Replace the switch on it.
2, high-voltage transformer damage: many friends have encountered such a problem, that is, the high-voltage transformer is bad. After the boot if the lights are on but the turntable does not move, it means that it can not be heated, if it is normal to replace the high-voltage transformer can be.
3, the magnetron is bad: magnetron is bad mainly in the boot light but does not heat, generally this is due to the magnetron inside the aging filament broken. Solution: Speak during the inspection of high-voltage capacitor discharge, test filament winding, the normal is 0 ohms, if it is not so, it means that the magnetron is bad, change can be.
4, high-voltage diode is bad: this situation is also often the case, the disk is rotating, but does not heat, if this is the case in the overhaul of the filament winding should be measured whether it is normal, if it is normal to look at the high-voltage diode to see whether it is normal, if the test is infinity, this time to change the high-voltage diode.
Microwave oven does not heat how to do?
1, the microwave oven does not heat this fault refers to the microwave oven powered on after the start of the food is not heated, but the general furnace light can be lit, the turntable will also rotate. No heating fault is mainly due to microwave oven no microwave output. Oven light can be lit, the turntable will rotate, indicating that the high-voltage transformer before the circuit work is basically normal.
2, overhaul does not heat the fault, pay attention to not be confused with the failure to start. After dismantling the chassis, first of all, should rule out the possibility of power control switch s5 disconnection, usually available multimeter measurement can also be power control switch s5 ends of the temporary short after the test machine judgment. Then check the parts of the high voltage circuit and its connection.
3, due to the part of the circuit total *** only 4, 5 parts, so even if each check is also very fast, usually first check the magnetron MAG pins and connectors between the loose or poor contact, if normal, and then check the high-voltage diode vD, high-voltage capacitors, high-voltage transformer c, T, magnetron and its connected connectors and weld points, usually very quickly to find the fault.
4, practice shows that usually to high-voltage diode and high-voltage transformer damage is more common, especially the former is the main, so when encountering this kind of failure can be the first to check the tube, often can receive twice the result with half the effort.
Above we introduced you to the United States of America microwave oven does not heat what is the reason? The United States microwave oven does not heat how to do the relevant issues, microwave oven does not heat the above reasons we can try to analyze whether it is consistent with our situation, so that we can find the right way to deal with it.
