Recently I lubricated my treadmill belt, using 100% silicone lubricant, doing as the treadmill manual said to. I followed all instructions, but about 1 Minute into letting it run with the lubricant, the belt sounded sticky and the motor sounded louder as if it was working harder suddenly. I left it for a while and when I came back to use it,the motor continued the noise and about 10 minutes into walking the motor started smelling hot and when I took off the panel the motor was very hot to the touch. The belt FEELS fine, but obviously something is up. No cotton candy-ing to my knowledge, underneath of belt doesn't feel sticky... Why did lubricating it ruin motor?
