I’ve recently just cleaned the unit using a blower and vacuum. Tried running the treadmill and noticed a light/spark flashing every now and then coming from the motor which comes with a weird clicking sound. Just worried because it looks like a spark to me and might be a fire hazard. The unit is 2 years old and is working fine, just not sure what that is. Any response would be greatly appreciated
