Error 46: AC Incline Timeout DOWN
Switch not encountered within time limits going DOWN.
Cause:
Incline is commanded to move down to the home switch, but does not encounter the switch within
expected time limit.
Service:
Most likely problem is the internal thermal switch of the incline motor opened due to over-use. This will
cool in about 20 minutes and allow full use again, so if the product ‘fixes itself,’ this is not a permanent
failure that needs addressing. If the problem persists, inspect the LED indicators on the LCB to ensure
the LCB is getting the commands to move the incline. Listen for the relay click. Inspect the incline motor
to see if it is jammed. Ensure the lead screw is clean of debris and dust and is properly lubricated.
Ensure the tube nut is still threaded on to the lead screw and isn’t separated, run off at the top
• Incline motor’s home switch is out of position
• Incline motor’s home switch is broken
• The gear drive is worn or spinning on the shaft
• Fuse blown on LCB
• Relay bad on the LCB
• Incline motor is unplugged or the cable is damaged
• Incline motor lead screw requires lubrication
