[FONT=Times New Roman][SIZE=3][COLOR=#000000]My microwave was making a loud hum when turned on and did not heat the food. The unit continued to hum and died after about 5 seconds of running. I have replaced the RECTIFIER (Diode) AppliancePratsPros Part Number: AP4362626, and a bad thermal fuse AppliancePratsPros Part Number: AP4360246 (Switch / Fuse combo). The unit only ran for about 3 seconds before blowing the fuse again. What would be the next part to try replacing? Any help would be greatly appreciated…[/COLOR][/SIZE][/FONT]
Have you tested those parts before you replaced them or it was just a guess?
