Haier microwave oven repair center, Fuzhou 【0591-83986202】 mainly microwave maintenance of professional services unit, Haier microwave oven work time not only exists within the high-voltage, high current, but also the microwave radiation, if the improper maintenance methods, not only will many detours, More importantly, maintenance personnel may have been high-pressure shock and microwave radiation, endangering personal safety, and even the body in the long run to give users excessive microwave radiation and cause irreparable damage. Therefore, the maintenance of microwave prerequisite is the need to fully understand the basic principles of control over anti-leakage and high pressure microwave knowledge of electric shock if you have not done, be sure to study hard to grasp in a microwave oven after repair. 


 Microwave common sense: 


 Mainly by the microwave oven magnetron, high voltage transformers, high voltage diodes, high voltage capacitors, door chain switches, control switches, cooling fan motor and turntable motor and other component parts, work Shiji memory in high-voltage, high current and microwave radiation Therefore, maintenance of some other household appliances maintenance microwave more than the particularity and complexity, especially the safety issue is more prominent. In view of this the following when asked about the maintenance of microwave oven safety precautions, and then describes maintenance skills. Security: the microwave is a more specific appliance, the working time not only exists within the high-voltage, high current, but also the microwave radiation, if the improper maintenance methods, not only will many detours, more importantly, maintenance personnel may have been high electric shock and microwave radiation, endangering personal safety, and even the body in the long run to give the user exposure to excessive microwave cause irreparable damage; Therefore, maintenance of microwave prerequisite is the need to fully understand the basic principles of control of excessive leakage of microwave anti- related knowledge and high-voltage electric shock if you have not done, be sure to study hard to grasp in a microwave oven after repair; usually repair the safety of microwave ovens is important to note the following. No. 1, disassemble maintenance, they must first of the safety-related parts and components to check whether the key is to look at the closed door, the door gap is too large observation window is broken, and shell on the furnace chamber Sealing-off spot has, whether the defect and the door seal uneven and so on. This is mainly to check for the possibility of excessive leakage of microwave. If it is found, it should first repair; Ruoyin lack of parts or other reasons can not be repaired temporarily, you can pre-machine the other failures, but repaired after Do not force the other fault, but can not be delivered to users, safety problems must be ruled out completely after to delivery. Haier microwave oven repair Fuzhou No. 2, if the need to check inside the circuit, after the demolition should normally be in the microwave power. Disassemble after the first high-voltage plastic insulated handle screwdriver to short across the capacitor discharge, in order to avoid accidental electric shock maintenance. This is because the microwave power, the high-voltage capacitor high voltage may still exist, especially near the stove off even more, do not think that power after the safe. 3 Haier microwave oven of Fuzhou maintenance, in addition to measuring 220V mains voltage screening, not very sure in the case of electric power should be no examination. If you do need to check the power, you must first disconnect the high voltage circuit, not to the work of the magnetron, and then start checking to ensure personal safety. As for the inspection of the magnetron and power supply circuit, unless you have the necessary professional knowledge and experience maintenance equipment, or check the power mode should be used to ensure safety. Practice shows that, as long as the relevant skills to master the essentials, checking power check is not much worse than the power to determine the rate of failure even better than some power checks. 4th Microwave repair, Fuzhou, Huimin repair parts needed to be demolished in the inspection or replacement, dismantled one by one remember when the original location of the demolition of parts, especially the security agencies and high-voltage circuit components should pay more attention, and Good to be placed after the demolition in order to prevent the loss, resulting in unnecessary trouble; reload should be installed one by one accurate reduction, and tighten the fastening screws and other fasteners for each, do not install the wrong, or the installation of washers and so easy to ignore the missing small parts. For replacement parts, pay attention to try to use the original type accessories. If not, can be similar to the characteristics and mounting dimensions of the substitution of parts for replacement. The main use of microwave ovens are: food cooking, food thawing, food reheating, food drying, dehydration, food preservation, sterilization, etc., there can bake moth sweater, homemade dried flowers, making ceramics, cooking tea fruit juice , re-crisp the food, utensils disinfection, fried melon seeds, nuts, peel the vegetables, make magical effect of drug decay fungus.
