Where can I find a place to repair Samsung microwave ovens in Wuxi?

Wuxi Samsung microwave oven maintenance: Yangquan Middle Road, Yicheng Street, Yixing City, Wuxi City. Maintenance skills

First, before disassembly and maintenance, you must check the safety-related parts, mainly to see whether the oven door can be closed, whether the gap of the door is too large, whether the observation window is damaged, whether the solder joints on the oven cavity and shell are off-welded, and whether the oven door gasket is defective and uneven. This is mainly to check whether there is the possibility of excessive microwave leakage. If problems are found, fix them first; If it can't be repaired temporarily due to missing parts or other reasons, you can repair other faults of the machine first, but don't use it reluctantly after repairing other faults, let alone deliver it to users. You must completely eliminate potential safety hazards before delivery.

Second, if it is necessary to check the internal circuit, it is generally necessary to disconnect the microwave oven after cutting off the power supply. After disassembling the machine, first use a screwdriver with plastic insulated handle to discharge the short circuit at both ends of the high-voltage capacitor to avoid accidental electric shock during maintenance. This is because there may still be high voltage on the high-voltage capacitor after the microwave oven is cut off, especially for the stove that is cut off for a short time. Don't think it's safe to lose power.

Third, in addition to measuring the 220V mains voltage and other inspections, try not to check with electricity if you are not quite sure. If the power-on inspection is really necessary, the high-voltage circuit must be disconnected first to prevent the magnetron from working, and then the power-on inspection is carried out to ensure personal safety. As for the inspection of magnetron and its power supply circuit, unless you have the necessary knowledge and experience of professional maintenance equipment, it is best to use the method of power-off inspection to ensure safety. Practice shows that as long as the relevant skills are mastered, the power-off inspection is not much worse than the power-on inspection, and the speed of judging some faults is even faster than the power-on inspection.

Fourth, when the parts need to be disassembled for inspection or replacement during maintenance, the original positions of the disassembled parts should be remembered one by one, especially the parts of the safety mechanism and high-voltage circuit, and more attention should be paid to putting them away after disassembly to prevent them from being lost and causing unnecessary trouble; When reassembling, it should be accurately reset and installed one by one, and all fastening screws and other fasteners should be tightened. Don't misplace or miss small parts that are easily overlooked, such as mounting washers. If parts need to be replaced, please pay attention to the original model parts. If not, it can be replaced by a substitute with similar characteristics and installation dimensions.

Fifth, after the overhaul and installation of all parts, check again whether the oven door can be opened and closed flexibly, and at the same time pay attention to whether there is any abnormality in the door gap, door mat and observation window, as well as whether the adjusting buttons, switches and other parts are normal, and can be used only after it is confirmed that there is no problem.
