Microwave oven this kind of home appliance everyone should have usually seen it! Now a lot of families have purchased this appliance. Microwave oven is the use of food in the microwave field to absorb energy and let itself heated a household appliance. Microwave ovens have many advantages, its heating speed is very fast, and the operation is flexible, safe and convenient. Now almost every home appliance has a microwave oven. Have you ever used a microwave oven? If the granz microwave oven does not heat up do you know what is going on?

Granz microwave oven does not heat the reason

1, the circuit pressure is too large, resulting in poor contact or uneven heating

2, Granz microwave oven battery capacity is insufficient to make the Granz microwave oven does not heat

3, because of the prolonged use of Granz microwave oven caused by the control of heating pipe Aging or damage

Granz microwave oven does not heat how to do

Granz microwave oven does not heat up the reasons may be: broken fuse, temperature sensor failure, high-voltage wires close to the chassis, low-pressure failures, high-pressure faults, the following Xiaobian for you to introduce the details of the Granz microwave oven does not heat up how to do.

Granz microwave oven does not heat up how to do a: broken fuse

In the encounter Granz microwave oven does not heat up, the first reaction is that the fuse is broken, change a fuse on the good. If the fuse is intact, the situation is not clear can also be handed over to a professional repair master to get it done.

Granz microwave oven does not heat how to do two: temperature sensor failure

In the case of microwave oven does not heat, heating often burn the food paste, it may be due to the Granz microwave oven temperature sensor failure, replacement of the temperature sensor can be.

Granz microwave oven does not heat how to do three: high-pressure line close to the casing

In the process of using the microwave oven found in the furnace appeared open fire, after the microwave oven can not be heated up, it may be high-pressure line close to the microwave oven casing, high-pressure line after the separation of the fault is eliminated. In addition, heating fried food in the microwave oven can cause the same consequences, so do not take the risk of heating high temperature and high heat in the microwave oven.

Granz microwave oven can not be heated how to do four: low voltage failure

Granz microwave oven low voltage failure is generally due to the low-voltage power supply line has a problem, the formation of 220V AC voltage is not sent to the high-voltage transformer or inverter board, high-voltage localization does not work to provoke not heating. Low-voltage localized mostly due to timer damage (mechanical microwave ovens) or computer board relay damage (computer-type microwave ovens), there are a small number of microwave ovens due to microswitch.

Granz microwave oven can not heat how to do five: high-pressure failure

Granz microwave oven high-pressure failure is generally caused by three major components, high-pressure diode, magnetron, high-voltage transformer. Because the microwave oven use time is different, the three major components of the chance of damage also exists, granz microwave oven does not heat most of the high-voltage diode due to short-circuit. According to time speculation, within 8 years of the microwave oven does not heat the diode short-circuit caused by the proportion of more than 8 years outside the microwave oven does not heat the magnetron caused by the majority of not heating. And there is a very small part because the high-voltage transformer damage caused by microwave ovens do not heat, such causes are less.

The microwave oven power transformer removal, first unplug the power supply, remove the microwave oven cover and make the capacitor discharge, remove the main transformer primary and filament all the leads from the chassis under the removal of the fixed transformer mounting bolts, and then take out the transformer, reinstallation of the new transformer, the test machine troubleshooting.

If the microwave oven can operate normally, but can not be heated, is the furnace inside the high-pressure part of the magnetron, transformer, grounded bidirectional tube (high-pressure diode), high-pressure fuse and high-pressure capacitor one of the bad. You can disassemble the shell, check with the plastic shell of the high-voltage fuse is burned, replaced with the same specifications of the test machine, Granz microwave oven does not heat the problem is solved.

If the invalid, microwave oven magnetron and high-voltage diode is more likely to be bad, capacitance capacity drop will also lead to the furnace does not work when the heat (if the insulation is poor to the ground that is burned insurance and high-voltage diode). Can be dismantled and inspected by yourself, first use the multimeter × 10K file amount of high-voltage diode, a direction of the other direction is not pass about 30 ~ 150K (not uniform), if the normal amount of magnetron (filament two feet × 1 file amount of pass can be), capacitance capacity decline with capacitance table to identify (and test its insulation to ground to be qualified), the transformer is very unlikely to be bad.

Granz microwave oven does not heat up the reasons and solutions to the editor has been introduced to you, in fact, the principle of the major brands of microwave ovens are the same, so no matter what brand of microwave ovens, in the future as long as there is not heating the situation can be taught in accordance with the small method to solve the problem. I believe that the possibility of solving this failure is not heating is very large, but in addition to these reasons microwave ovens do not heat the reason there are a variety of reasons, you can go down to do a detailed analysis.
