Anyone know of a good appliance repairman, maybe in the North metro area?

FYI, I have a dishwasher, 6 months out of the one year warranty that's dead. No lights on the control panel. Tried resetting breakers, tried resetting the inside outlet/breakers, tried different outlets w/extension cords etc. Tried leaving it unplugged for awhile to reset and then re-plugging it back in, all a no-go. Took off the kick panel and the door panel off to check connections and all seems well. I do not have a multi-meter nor do I know how to use one. I suppose a board may have gone bad but I hate to throw money at replacing those not knowing where the real issue is.

If you have any tips or know any guys that do reputable work, let me know.
