Hi ddmyatt.. They sell what is call dry lube at sports store's. for spraying under the tread's and on the wheels that the tread run's on.. Lift the tread and spray as far under it as you can on both side's. She'll be lot's quieter then before and lots easier on the motor too..

Had my TC5000 for a year and this is the first time this happened. I use it everyday. Googled "Bowflex Teadclimber error codes" and found this link  download.dfxi.com/supportdocs/AM/Bowflex/BFX_TC135_AM_2008.pdf which is a pdf manual. 
I'm going to try this fix now, hope it works for you and me
Here's what it says for ERR LS:
Belts stop turning and “err LS” or “err OS” is displayed Calibration Re-calibrate machine using Owner’s Manual calibration procedure. Speed sensor 1. Cycle power off and on. 2. Put the machine in calibration mode (see Calibration procedure in Owner’s Manual) but do not start the calibration routine. 3. Remove right rear plastic cover to view LED diagnostics on control board. Caution: Machine is on. Current is active!! 4. Locate LED D on the motor controller board. LED may be lit or unlit. 5. Manually advance the treadle with your foot, and check if LED D is blinking. 6. If LED D is not blinking, then the speed sensor is not supplying a signal. Check that the speed sensor wire is plugged into the motor controller board, to the connection labeled “P1”. Check connection of speed sensor to jumper wire. Check speed sensor adjustment (use business card to set gap between sensor and pulley). If LED D still does not flash replace sensor. I/O cables If LED D is flashing when the belts are turning but err LS or OS persists check connections and for signs of visible damage to any of the three I/O cables. If no damage, check continuity using a multi-meter. If a multi-meter is not available contact customer service for replacement cables and further assistance.

Unplug your machine, restart it and try to calibrate it one more time. I had to do this with mine and it did take more than one try to get it to recalibrate again.

TC1000 from Bowflex, works okay for 15 mins then the speed surges ahead and stops dead with error E1
