Treadmill Motor Control Boards

Treadmill Motor Control Board

How do you know if your treadmill motor control board (MCB) is bad? This is the part of the circuit board that controls the speed sensor, so if your belt is running off-speed all of the sudden and you get an “LS” display, for low speed error, then you may likely have to replace the MCB. (Check the fuse first.)

They don’t often fail on their own though; usually it’s because you failed to lubricate the belt. The good news is, MCBs are easy treadmill replacement parts to install and can be bought through Amazon and configured for most of the major brands of treadmills.

The bad news is, treadmill MCB parts are not cheap so be sure it’s the problem before you spend the money to replace it. If you know the problem is the treadmill motor itself, you can also replace that.

Treadmill Belts

Treadmill Belts

Treadmill belts cost $75-$150 and are something you can replace yourself. They come pre-lubed and you’ll need to know the width of your rollers and your treadmill’s make and model number before ordering any treadmill parts. We recommend you buy through Amazon (the belt will ship from and be sold by Treadmill Doctor) to get a high quality belt.

Treadmill maintenance items such as lube kits, surge protectors, and safety keys can be ordered online from Amazon, no need to pay the high price charged by the machine’s manufacturer. Many of these parts are generic and will work on any machine.

Don’t Void the Warranty

Keep in mind that tinkering under the hood unnecessarily and replacing some worn or defective part could void your treadmill warranty. Read the paperwork first before you get started with repairs. Treadmills are heavy and expensive to haul to a shop, and it can be costly to have a technician come to your house if the warranty is expired, but if you can handle certain repairs yourself you’ll save time and money with these treadmill parts and be back to your workout in no time.
