This is a Horizon / AFG - Advance Fitness Group motor control board for multiple treadmills.  Our refurbished control boards are stripped down and rebuilt with better than new components by professional technicians.  Refurbished control boards are put in a treadmill and successfully tested for full functionality - prior to being sent to you. Each control board comes with a 6-month warranty which begins the day you receive it.Warranty claims (repair and shipping) will be completely covered by us, unless we find that you have tampered with the repaired circuit board.  All of our control boards are marked inside and out, a sticker is placed on the seam of the plastic, and the serial numbers are recorded.  If for any reason, the sticker is damaged, or the markings / serial numbers do not match - the warranty will be void. If your warranty is deemed void, we will ship the drive back to you at your expense - should you so choose.Free domestic ground shipping only.  Expedited shipping available at buyers expense.Keywords: control board, Horizon, treadmill, circuit board, lower board, lowerboard, control board, AFG, Advance Fitness Group.68Where used:Advanced Fitness Group3.5AT - TM659B - 2015HorizonHorizon - CT5.3 - 2012 (TM660)Horizon - CT5.4 - 2013 (TM684B)Horizon - T100 - 2011 (TM629C)Horizon - T101 - 2011 (After SN TM6211006CL00401)Horizon - T101-03 - 2012 (TM659)Horizon - T101-04 - 2013 (TM684)Merit Fitness725T Plus - TM398 - 2011Tempo Fitness622T - TM452 - 2012632T - TM667 - 2012
