To troubleshoot a Proform treadmill with power problems, check if the surge protector is switched on and correctly grounded, and make sure the power cord is firmly plugged into the protector. The key should also be properly inserted in the console.
Wait 5 minutes before pushing the switch to reset a tripped circuit breaker. Another method to troubleshoot power interruptions during use is to unplug the power cord from the surge protector and then plug it back in after 5 minutes. Try removing and reinserting the console key as well.
If the console display fails to work, find out if the batteries need replacement. If batteries are not required, pull the key from console, disconnect the power cord, and remove the console hood by unfastening screws. Spin the pulley to align the magnet and reed switch with a slight gap, and then change the hood. Test the treadmill to check for an accurate speed reading.
To troubleshoot a slow walking belt, make sure the surge protector is suited for the treadmill by checking the specifications in the manual. Use an Allen wrench to rotate the rear roller bolts in a counterclockwise direction. Lift both ends of the walking belt a few inches while keeping the belt in a center position. Repeat the procedure if the walking belt is still loose after running the treadmill for a few minutes.
