Heating, Air Conditioning, Fridge, HVAC/microwave problem


I have a over the stove microwave that I purchased back in 2007
model# GEHVM1750SM1SS serial #901060B it has just started acting strange,when I start to cook something it works fine then the light dims and the turntable slows down, it also causes the living room lights to dim,this only happens for a few seconds but reoccurs thru out cook time,I had electrician come check all the wires in house panel to ensure there wasnt a loose wire,I did this because I had a hot tub installed and wanted to be sure it wasnt that that causes the problem
can you please advise what may be causing this to happen

Sounds like high voltage problems in the microwave.  There is a high voltage and a low voltage section within the electronics of your microwave.  Lights dimming would direct me to check the high voltage system....Magnetron tube, hi voltage transformer, diode or capacitor.  Keep in mind when working on microwaves, even with the unit unplugged, there is a potential of 4000 volts that can zap you if you do not discharge the capacitor before checking components.  If you are not familiar with electricity and stored voltage in a capacitor, I recommend you take your u nit to a certified microwave repair service company.  Good Luck....
