Is there a fuse on the MCB of Horizon ct5.3 if there is where is it located? Pls advise thx

Hey Sharon,
Hope so you're doing fine, there is typically no separate fuse on the MCB (Main Circuit Board). The MCB itself is responsible for controlling the incline and belt functions of the treadmill. If the top board turns on but the incline and belt do not run, and the MCB is flashing a safety key error message, it suggests that the safety key might not be properly engaged or there could be an issue with the safety key sensor.
To troubleshoot the problem, make sure the safety key is securely inserted into its slot and properly aligned. Check for any visible damage or debris that might be obstructing the safety key sensor. If the issue persists, it is recommended to consult the treadmill's user manual or contact Horizon customer support for further assistance. They can provide specific troubleshooting steps or guide you through any potential repairs or replacements that may be necessary.

Hope so this will work for you!

Hi There, sorry to hear of your troubles. Could you mention what brand and model of treadmill? If this is a Horizon treadmill with E1 error, like models T101 and others from the years 2011-2013, there is one thing you can try. Unplug the treadmill and remove the motor cover to get to the Motor Control Board, or MCB. Be certain the treadmill is unplugged from the wall! Now, look on the MCB on the right side there may be ONE small blue "block" with a tiny screwdriver slot in the center, this is called a potentiometer, and if there is Only One, and a Horizon MCB, you can turn this pot to the right, clockwise, gently until it stops, and then back it off just a hair, reassemble unit, and try treadmill. If this doesn't help, the MCB most likely needs servicing due to failing storage capacitors which get quite hot while in use and can degrade over a few years of service. You can find some help by looking up jatinah electronics, who repairs these modules. Good Luck! ;o)

Hi There,
If it is new ring the retailer as it would be under warranty.
