My healthrider s300i softstrider treadmill doesn't incline anymore do you know what i can do to fix this?

sounds like the belt is slipping you may be able to just tighten it up

This could be a number of reasons.
A authorized repairer would be needed.

Check the fuses under the lower hood. One should be a 10 amp fues, the other should be 15 amp fuse.

Replace them if blown. If they should blow again, move the treadmil to an outlet closer to the fuse box/breaker box of the house. the house wiring where you have the treadmill may not be adequate for the treadmill.

could be bad incline sensor or c/board is going bad. one more try bipassing the board with power to the incline motor fully powered 18volt batt will or higher will move the motorby flipping thr wires on the bat the incline should go up and down. if working ok then check board

you can try to rent a set at AutoZone. when you return it they will give your money back. try standard and metric. depending on manufacturer of treadmill.

just change the keypad
