Healthrider L700i (HRT15920) very sudden stop

in Treadmill Problems
Sudden stop very dangerous. Not a shutting down stop, a hitting the brake hard kind of stop. Happened in the past, oiled things, problem seemed to go away, but came back. ICON says probably controller, they don't have part. Found part here (they gave me web site address.) Before I spend $200 on ICON's 'probably' does anyone have experience with this problem. Treadmill is 13 years old, but not many miles (802 to be exact.) Second option presented by ICON was a $600 motor.

    Sounds like you have a motor controller issue, but also I would recommend to lube the Belt & deck and may have to replace the Mylar or the Running belt.

    Even though it is pretty low mileage for 13 years, I did pay a LOT for this treadmill at Nordic. But I'm hesitant to spend any significant $$ on it without feeling as confident as possible that I am fixing the real cause of the problem. I lubed all logical moving metal parts in the past. I just did that again, and am waiting for another failure. My concern is, it acts like a seizure, since if you just hit the stop key, it comes to a comfortable gradual stop. And a $600 motor isn't under consideration. I was hoping you might have some insight into what would cause the controller to cause the motor to lock-stop?
    Perhaps a sensor of some sort, versus the actual controller or motor?
    I do appreciate your help here.

    The belt & deck builds up friction when you walk/run on it, without proper deck lube you can cause the motor controller to overheat and shut down.
    Walking Belt Lube Instructions
    World Famous Treadmill Lube
    This lube works on most manufacturer's treadmills and has been proven to be the most effective general lubricant available for treadmills. If problems persist after lubing, a parts problems exists and the parts require replacement. Call or email TreadmillDoctor.com with any questions.
    STEP 1
    Inspect belt and deck. The deck should be smooth. The belt should have a consistent feel from side to side (a belt can be worn out without any sensory signs of a problem). If you feel deep grooves in the deck or uneven wear on the underside of the belt, part replacement is necessary. Continued use of your treadmill may damage expensive electrical components.
    STEP 2
    To inspect the belt and deck visually or to clean underneath the belt before applying lubricant, the belt must have the tension reduced. Loosen the tension roller by following the instructions in your owner's manual. Do not loosen the bolts in the tension roller too far or the bolts will come out of the roller shaft. This step may not be necessary for your treadmill model or belt and deck condition.
    STEP 3
    Contaminants are the worst enemy of your belt and deck. Some treadmills may have an excessive accumulation of dirt and contaminants. If these are trapped during the belt lube process, significant damage will occur. If contaminant removal is necessary, loosen the belt by following step 2, lay the treadmill on its' side, and use a nylon brush to loosen contaminants that have accumulated on the inside of the belt. Clean the deck with mineral spirits in a well-ventilated area. Allow the deck to dry before lubing or tightening the belt.
    STEP 4
    Lift the belt and use approximately ½ of the tube by squeezing the lube in the walking area lengthwise. Move to the opposite side of the treadmill and repeat using the remainder of the lube. Use all of the contents of a single container during application. Do not put any lubricant on any surface with which your feet make contact. The lube will spread evenly in the next step. Do not perform this step by hand. The lube is usually not harmful to the skin but has the potential to permanently stain fabric. 5. Adjust belt tension and centering following your owner's manual instructions if you have loosened the belt to clean. LOOSENING THE WALKING BELT IS NOT NECESSARY JUST TO APPLY THE LUBE. Start the treadmill at 2-3 mph and allow to run for 5 minutes without walking on the treadmill. Check centering carefully and adjust as needed following your owner's manual instructions. Using your treadmill's handrails and safety switch for safety and support, walk on the treadmill at 2-3 mph. CAUTION!!! BELT MAY HESISTATE. THIS CAN CREATE AN INJURY IF BELT IS

    I lubed my L700i per suggestion 2 years ago, and problem went away. Until today, not only did I get a sudden stop, but motor speed was erratic when restarted. Guessing the controller this time? This is a huge 15 year old unit that hasn't been heavily used, is there anything to do with such a monster that doesn't require paying to have it hauled away? Or any other suggestions?

    Not really , besides replacing the motor controller.
