Recently, a brand of air conditioner in Mr. Sun’s home suddenly could not be refrigerated. Later, he searched a website that claimed to be the special after-sales service provider of the brand, and called the hotline at the beginning of “400†on the website to make an appointment for repair. The air conditioner was not repaired and still had a stomach.
On July 28, Mr. Sun called to make an appointment to repair the air conditioner. The maintenance worker said that he needed to replace the parts and charged a maintenance fee of 500 yuan. Later, Mr. Sun found that the air conditioning and refrigeration were not repaired at all, and wanted the maintenance workers to come again, but the maintenance personnel refused to come to the door again and the attitude was bad.
Later, Mr. Sun discovered that the maintenance website was not registered in the industrial and commercial department, and a brand air conditioner manufacturer did not authorize it. It was a cottage website.
An air-conditioner sales person reminds consumers to guard against counterfeiting and sell the latter to pay attention to three points: First, the appliance repair should contact the after-sales personnel according to the telephone number on the manual. Do not superstitiously call the "400" phone. This type of phone is not necessarily the official customer service. hotline. Second, the “cottage website†often provides after-sales service for multiple brands of home appliances, while the regular after-sales service center generally only provides after-sales service for the branded home appliances. Third, when repairing home appliances, carefully check the work permit, work order and maintenance documents of the maintenance personnel. In addition, save the maintenance records, and pay for the repair vouchers when paying for repairs, and promptly complain to the industry and commerce department in the event of a dispute.
Rectifier Diode(Standard Diode)
Rectifier Diode(Standard Diode) utilizes the unidirectional conductivity of the diode, which can convert the alternating current of alternating direction to a pulsating direct current of a single direction. Rectifier diode – diode designed for rectifying alternating current (mostly with low power frequency – 50 Hz at high power emitted during load). The main task of the rectifier diode is to convert AC voltage into DC voltage through application in rectifier bridges. The variant of rectifier diodewith the Schottky barrier is particularly valued in digital electronics.
