Anybody work on these heaters? Bought this at a state auction for thawing out mobile homes and heating pole barns to get the snow to slide in the Winter instead of shoveling. Motor runs great, the fan runs fine, but as soon as you try to start the burner it locks out on burner failure. The CAD cell is clean but I didn't check the ohms on it yet. It locks out within 5 seconds and I would think the CAD cell would have a longer lockout time? Any pointers would be appreciated.....
