im looking for a belt for a york pacer 3100 treadmill

Hi,

The L5 message means that there is a problem with the speed setting switches. Some models have one set of speed adjusting stitches on the handlebar and another set on the console. One of them is defective and is causing the problem.

my treadmill is showing error 07, what does thismean?

York treadmill T101 will not run has a error L5

Error 7 is a Safety Key Error..
that's the red magnetic circular thingy on the console.
Simply secure the safety key in place and try it again
