How to fix ProForm 831.299263 Treadmill when it won't turn on?
- PPaul BrownAug 12, 2025
If your ProForm Treadmill isn't powering on, ensure the power cord is plugged into a UL 1449 listed surge suppressor (TVSS) with specific ratings: a UL suppressed voltage rating of 400 volts or less, a minimum surge dissipation of 450 joules, and electrically rated for 120 volts AC and 15 amps. Note that the treadmill isn't compatible with GFCI-equipped outlets. Also, check that the key is fully inserted into the console, the circuit breaker near the power cord hasn't tripped (reset it after five minutes if it has), and the on/off switch is in the 'on' position.
