kids ran incline to the top and it tripped out. Err 77 pops up on screen after 30 secs when reset or turn on. can i remove the motor and reset or is there an internal reset on the motor or control panel board?
@boboatl that code means the potentiometer value the console is reading from the lift motor is out of range. This can happen when there is a bad wire harness connection or a damaged wire harness. It could also just mean the incline motor needs to be adjusted back into range. If all wire connections look ok, the incline motor will need to be adjusted. Try this, it’s from a somewhat different model but may still work for yours. Check to see if the running deck is raised to high incline level or if it is at the low level. If the running deck is at a low position press the incline up button. This will cause the incline motor to raise the running deck up. When the deck gets to a mid-level position, press the incline up button a second time to stop the deck. If the running deck is in a high incline position, use the incline down button to adjust the deck to a mid-level position. Once the unit is in the mid-level position, power the treadmill off for 5-seconds and then power it back ON. Start the treadmill. Once the treadmill starts the running deck will move to the level 0 position. See if this flowchart TReadmill-E6E7XT36_46_66_6800.pdf will help you with that.
