NordicTrack commercial 2450(NTL17221) problem

Hello everyone,

I recently replaced the controller on my treadmill, and it seems to be functioning well overall. I can start and stop the machine, and the incline/decline features are working fine without any load on the belt.

However, I’m experiencing a problem when I step on the belt. It slows down significantly or even stops moving if I apply pressure. During this time, the controller blinks red. I’ve checked the deck, and it appears to be in good condition. The belt is well-lubricated, and the tension seems to be just right—not too high or too low.

Does anyone have any advice on what might be causing this issue?

Thanks in advance for your help!

Best,
Tomas
