Have you considered moving the doorway first? Or you could go with what all these other people are suggesting: turn up the speed and then ride it like a tank through the wall. If you have drywall you might slide right through. Please record the whole thing for the rest of us. We all need a good ab workout from laughing at the result. http://www.floridaaesthetics.com/medical-weight-loss

This condition is when the treadmill goes to full speed as soon as you power up the treadmill. Typically when this occurs, it is an indication of a short circuit in the motor controller.

ProForm Treadmills have a reset procedure for the incline function. With the key inserted in the console, activate the incline; while the incline is changing, remove the key. Wait 30 seconds, then replace the key. The incline should to maximum, then to minimum, resetting its limits. It worked for mine just 10 minutes ago; the procedure is in the manual if you have it. Good luck!

Open the cover where the main motor is there
Tight the connector for Incline motor, and clean it with special contact cleaner for electronic.
2) See if there are wires loose,
3) Measure the 110 vac for forward and backward,
4) If there are , measure the l. switch or Capacitor for faulty and replace.
5) If there nOT 110VAC in forward or backward, replace the controller board motor.
6) If there are 110VAC, replace the Incline motor.
Blessing.

Did the shop only do a continuity check or a real load test with amp check also? Motors can look good and run with no load but fail under load.
