My microwave is Samsung MW640BA. I have had it for two or more

Resolved Question:

My microwave is Samsung MW640BA. I have had it for two or more years now. When i heat food up, sometimes the microwave just randomly stops working. When i remove the plug and switch it back on again, it would start spinning, with lights and sounds on but it either would stop mid way or would not heat the food. It randomly gets normal after a little bit. What should I do about this?

normaly this is caused by a faulty door switch, its not contacting all the time thus its itermitent, check the door switches and replace the bad one. the diagrams for this show the location of the switches section 8 on this diagram, the switches are #12, thanks Bryan

okay but what can i do about it? like i have no experience with this. can you explain what to do step by step?

and to replace a faulty switch, how much does it cost?
Expert:  Bryan replied 7 years ago.
well the switches are not expensive but you should if your not sure get a tech to do this, microwaves are dangerous to work on. this being a countertop unit it may be cheaper to replace the microwave, I cant really explain step by step how to do this, the diagrams are not that clear, thanks Bryan
