I would like the contact info for a good Harman dealer, there must be a good dealer somewhere in this country!

Stove is set to burn wood pellets and the status board shows 4 blinking lights, problem started after I opened the door when the stove was trying to light, wanted to clear some ashes out of the pot before the fire got started. It wouldn't start or run at all, after a good cleaning and blowing a little air thru the pressure differential switch I got the stove to run on manuel mode but it won't light itself. Called my dealer who thought I shoud start with the ESP probe and replace that first, I have cleaned it with a light brush, any thoughts?
