I purchase this brand new REEBOK GT40S MOTOR CONTROL BOARD from Treadmill Doctor intented to repair my treadmill, however it never happened as I received new treadmill on my birthday. I sort out the sold faculty machine to local repair man. And now I am going to sell the spare part for someone who need it. Please do test your machine and make sure it is error 2 faulty before purchase. I will do full return only when it's proved that the part has problem itself.
