Granz microwave oven is one of the microwave oven brands we use, but in the process of using, Granz microwave oven may not be able to heat up due to various reasons, which will affect our daily life. What should we do if the Granz microwave oven is not heating? What are the reasons and solutions for Grants microwave oven not heating? Below Luban to home I introduce the granz microwave oven does not heat up, granz microwave oven does not heat up causes and solutions.

Granz microwave oven does not heat up how to do

Granz microwave oven does not heat up may be due to the following reasons: broken fuse, temperature sensor malfunction, high voltage wire close to the chassis, low-voltage failure, high-voltage fault, the following I will introduce in detail how to do Granz microwave oven does not heat up.

Granz microwave oven can not heat how to do a: high voltage failure

Granz microwave oven high voltage failure is generally caused by three major components, high voltage diode, magnetron, high voltage transformer. Due to the microwave oven use of different length of time, the three components of the damage chances also differ, Granz microwave oven does not heat up most of the high pressure 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 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 whether the high-voltage fuse with plastic shell burned, replaced with the same specifications of the test machine, Granz microwave oven does not heat the problem is solved.

If invalid, the 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 ground insulation is poor that is, burn insurance and high-voltage diode). Can be dismantled and inspected on their own, first with a multimeter × 10K file amount of high-voltage diodes, 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 detect the insulation to the ground to be qualified), the possibility of transformer bad is very small.

Grants microwave oven does not heat how to do two: high-pressure line close to the case

In the process of using the microwave oven found in the furnace appeared open fire, after the microwave oven can not be heated up, may be the high-pressure line close to the microwave oven case, 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 does not heat up how to do three: the fuse is broken

In the encounter Granz microwave oven does not heat up, the first reaction is the fuse is broken, replaced 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.

Glance microwave oven can not heat how to do four: low voltage failure

Glance 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 caused by 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 does not heat how to do five: temperature sensor failure

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