Hi LOL, no Ghosts.
The reason for this is a frequency or noisy electrical line for some reason.
You will need to install a noise filter in the main line to the kitchens power.
Or you could put them on each appliance to prevent this from happening. It annoying but I see this myself on a much smaller scale with sensitive electronics:-)
If you rate me as good service or better, the system here will let me schedule free follow ups with you so we can remain in contact until you have this ghost gone form your kitchen!
Have a great day!
