Samsung DE92-03624B Main PCB Assembly Replacement Part - Compatible with Samsung Refrigerators for Home & Commercial Use

I had an issue with my microwave, when the door was closed, the light came on and the fan hummed quietly until the door was opened again. I ordered a board through this company and when installed, there was zero power to the clock display, thing was dead, but i had voltage after the fuses. I thought maybe it was coincidence they sent me a bad board, or one someone else returned, so I ordered a second one and same thing. I ended up buying one from a shop on ebay, plugged it in and back to normal operation. I am giving them two stars because there was no hassle returning the items, but also, you need to check your equipment you're trying to sell.
