Nordictrack Commercial 2450

I have a Nordictrack Commercial 2450 model # NTL17221.0 and am having issues with getting it to run. Belt runs fine off my battery pack, but when trying to start, the belt moves for a second and I get the 4 red flashes from the motor controller board. I originally replaced the MC and motor itself while it was under warranty with ICON, but replacing them did not work. Still getting the same issue, I was wondering if the MC-2100 available in the store would be compatible with my treadmill or where I should be looking for help.

Thanks for the help.
