Hi There,

Precor uses a pair of Triacs to drive the lift up and down. These triacs live on the lower board but are driven by the upper console commands via a serial link between the upper and lower. Most precor lift issues we see are related to the lower board but with Precor it could be an upper board or the CPU Chip that resides on the lower board or a failed Triac. Good Luck

Hi, It's probably the speed censor. Clean it up and should be good to go. When you disasemble it clean all other parts and put back togeather. Good luck

please see the details and proceed according. God bless you

• Error 05, Key Depressed at Power Up
  

I had the speed error on my precor 9.23. When I opened it up I found that there are two little round magnets on the belt pulley with a sensor mounted nearby. This must be how the computer know the speed of the treadmill. I noticed that there were several little metal shavings stuck to the magnets. Not sure where they came from, hopefully not another problem. However, I removed the metal shavings from the magnets and everything worked fine again. If anyone else has the speed error it might be worth a look to see if its the same problem.
