    Starts up... during acceleration, abruptly shuts off. Turn on switch and it (usually) works.

    Treadmill works with no load, then when you step on the track it slows down, you hear a lot of noise from the motor brushes, and the power switch trips off (circuit breaker function I guess). 9.33, same motor as the 9.31

Normally most home treadmills are 250-300lb user capacity.
Call Precor with your model # and S/N and they can tell you exactly.

SOURCE: Precor 9.4 Treadmill Incline Problem

http://www.youtube.com/watch?v=MIIxoPtvhy8

I bought a used Precor 9.4 treadmill, but the incline adjustment was not working.
So, I did the following.
1. Turn off, unplug the treadmill and wait for an hour (this is for safety
2. Remove the black motor cover
3. Observe the transformer to the right of the motor and towards the belt ( I point to it in the video)
This transformer converts DC electricity to AC electricity and the AC current goes directly to the Incline motor which is in the black box towards the front of the machine.
4. On mine the wires had come loose from the transformer, they were soldered on very poorly, the wires are stiff and you should be able to see 4 wires coming from the top of the circuit board and plugging into the transformer, I had three of the 4 wires loose.
5. If you are not comfortable working with electronics or soldering DO NOT DO THIS REPAIR, you could get shocked very badly if you just go poking around in there with metal objects, get a friend who knows how to solder or hire someone.

6. It took about 5 minutes I just heated up my $10 soldering gun from radio shack and soldered all the loose wires that were about a millimeter away from the tabs on the back of the transformer, and VOILA! The incline now works!

Is it on an extension cord? Take it off any extension cords and make sure it's on a dedicated 120v circuit. No other items on the circuit. Also, how old is it? Precor made a bunch of the 9.3x series from 2002-2005 with an aluminum tail roller that can cause problems. Check the back roller. Is is silver and non-magnetic? if that's the case, you have an aluminum roller and you need to contact precor. If you're the original owner of the machine, they should warranty the replacement of the parts, if not, you'll have to buy at the very least a running belt and new roller.

SOURCE: treadmill shuts off in middle of workout

A treadmill will shut down from to much friction which is due to high motor current because the walkbelt and deck are not properly lubricated. I would recommend replacing the motor controller,walkbelt,deck and applying .5 oz of lubricant on the deck every 3-6 months or 100 hours of use. This will extend your treadmill's life many years.

Error 27


Precor Error 27, Too Much Drive Motor Current Probable Cause 1. The running belt and/or deck are badly worn.
2. Drive motor is shorted or de-magnetized causing a high power demand.
Corrective Action
  1. Check the amp draw using a clamp on AC volt-amp meter during loaded and no load conditions and compare values to a similar treadmill that is known to have a good running belt and deck. Replace the belt and/or deck if necessary. Don't forget, some units have a double sided deck which means it may be flipped over rather than replaced if it has an unused side.
  2. Test unit with a known good drive motor. Replace drive motor if necessary.
