Our Samsung Microwave SMH9187S had to have it motherboard replaced twice now in less than 3 years due to known SE and 8888 errors, it now only runs a few seconds and stops. According to their own technical repair specialist it is a design problem with moisture which occurs when cooking food on the stove below the Samsung over-the-range Samsung Microwave SMH9187S units. (Very Expensive Issue for the consumer to continuely have to fix) see all the complaints with Samsung on the Internet regarding not fixing known design and potential safety issues. It appears Samsung discontinues its products once issues start to mount to avoid additional liability. It appears they like to use the customer as their product testing guinea pigs. Samsung just say it's now out of warranty and not our problem, call a Samsung authorized service company to have repairs made. This will be the last Samsung product we ever buy again. (that includes everything Samsung makes from refrigerators, oven, stoves washers, dryers, phones, tablets, TV,s, laptops, electronics, etc. an especially microwaves) When a company knowing refuses to stand behind its product, design and not fix defects the only course for consumers is to not trust or purchase any products from that company and warn all your friends and neighbors regarding of the companies business practices after the sale and they have got your money. Fool me once shame on you, fool me twice shame on me.
