Question about Samsung SMH7178STD Microwave Oven
Don't know that they had anything to do with the problem. When you say it doesn't start working I assume you mean lights come on, time counts down, fan runs but no heating occurs. If that is the case something has failed in the power circuit. Microwaves have a HV diode to rectify the AC to DC for the magnatron. 99% of the time this is what fails. When microwaves were expensive I used to fix a dozen a week with this problem. It usually blows because someone ran the unit with nothing in it. If there is no load for the heat it will build up in the magnatron and eventully the diode will blow. It could be something else but this is the most common problem and not an expensive fix.It probably is more than the average owner would want to tackle but a reputable appliance repair shop should be able to fix it quick and cheap.
