Tom Doyle for Model Number Samsung ME18H704SFS microwave Wife used the microwave to heat some food. Shortly after the whole house power cycled off/on. I went to use it shortly after and found it completely dead. Checked breaker & tested wall outlet and it is "live". Have checked all three thermal fuses, the one on top (good), and the two behind the control panel -- right side one (good) and left side one (good -- normally open). Checked the two 20 amp fuses behind the control panel on the circuit board. They both are good. Any further things to check? Yeah, I know, I should have a surge protector between the wall outlet and the microwave which I have now done. Thanks for your help!
Answer Tom, All the components you have tested that all check good is an indicator that a main control board failure has occurred. It is good you have a surge protector in line though for further problems. You will need to order the main control board DE92-03624B Read More...
