20 Most Recent Precor 9.27 Treadmill Questions & Answers


Fuse is a dead end in this case. Is there belt movement with the LS error, where the belt moves for a few seconds then quits? If so, there may be a problem with the upper - contact Precor and have them look up bulletins on that model/SN. If no belt movement, then there is a problem with either motor or MCB, probably MCB.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/russell_1d1c35fa8a5a0be4

This is a common issue. Over time the belt stretches. You will need to adjust the tension on the running belt to alleviate this issue. If there is no adjustment room left, then you will need to replace your running belt and deck surface. The link below will take you to the products for your machine. Please use your serial number to narrow down your choices.

Please RUN the software calibration for eady diagnostic and fix it. God bless you
However follow this steps and fix it. God bless you
Probable Cause 1. A failure in the upper PCA overloads the low voltage power supply and causes it to drop below the preset level.
2. A fault in the interconnect cable (upper PCA to lower PCA) causing the input voltage to the upper PCA to be too low. Corrective Action
  1. If the error message is continually displayed when the unit is powered up, the upper PCA needs replaced.
    External causes may make the error appear intermittently.
    1. If the AC input of the unit dips significantly during power up test sequences, the test could fail causing the error to appear.
    2. A treadmill connected to a non-dedicated AC circuit can experience this error intermittently.
  2. Determine if the interconnect cable is the cause by substituting a know good cable in place of the current cable. For test purposes, the substitute cable needs to be connected directly between the upper and lower PCA's, without routing the cable internally.

Are you sure the PSU is functioning? Check it with a multimeter set for DC Voltage. Compare what it is putting out to what the factory specs are.
