Fixing Treadmill Belt Problems
Most of the treadmill problems are related to treadmill belts. It is the core of your treadmill and takes the maximum workload.
Aligning the Belt
For the efficient functioning of the treadmill, ensure that the belt alignment is perfect. Ideally, it should be aligned straight down the centre of the track. However, it may shift out of alignment from time to time.
You can easily fix this issue by adjusting the bolts that are located on both sides at the rear end of the treadmill. Once you have made the adjustments, check the alignment again and repeat it if needed. Refer to the user’s manual for alignment instructions.
Test the alignment by walking on the treadmill for a few minutes and ensure that it stays centred.
Maintaining the Belt Tension
Your treadmill’s belt is kept at a pre-set belt tension that prevents it from slipping. However, the belt gets stretched out over time as it is subjected to the workloads of rigorous workout sessions.
This results in the belt getting loose and starts slipping during workouts. On the contrary, if the belt gets too tight, it may interfere with the normal functioning of the motor and rollers.
To determine if your belt has perfect tightness, you should try to lift the side of the belt from its centre up to 2 to 3 inches.
If you are not able to lift it this high, it indicates your treadmill belt is too tight. On the other hand, if you can easily lift the belt more than this limit, it indicates that your treadmill belt is too loose.
To keep a perfectly balanced belt tension, you should tighten the bolts of the loose belt and loosen the bolts of the tight belt.
You can adjust the rear roller by using the large T-shaped Allen wrench and tighten the rear tension bolts up to one-quarter turn. For a tight belt, you should loosen it up to a one-quarter turn.
Ensure to read the instructions given in the user’s manual before making any such adjustments to your treadmill.
Lubricating the Treadmill
Your treadmill belt needs lubrication for proper functioning as it is subjected to regular friction. Depending on the model of the machine, the lubricating procedure may vary from one treadmill to another.
There are some advanced treadmills that come with a self-lubricating mechanism. In such machines, a special wax is released by the machine automatically over time for lubricating its components.
You should check your user’s manual to find about the lubricating guidelines for your treadmill because any unwanted lubrication may damage the treadmill’s components. If your machine needs lubrication, always follow the instructions given in the manual.
Ensure that you have silicone- or paraffin-based lubricant with you. Loosen the belt. Lift one side of the belt and slightly pull it up. Insert the lubricant spray nozzle underneath and spray it over the centre area. Repeat it on another side.
Move the belt manually for about half a revolution and lubricate in a similar fashion again. When finished, retighten the belt again. Run the treadmill at a slow pace for about 5 minutes for spreading the lubricant evenly.
Take special caution to not spill the lubricant on the treadmill belt surface as it poses risks of slipping.
Replacing the Worn Out Belt
Over time, your treadmill belt may get worn out due to regular high-intensity workouts. You should replace your worn-out treadmill belt as it may lead to poor workout experiences.
To determine if your treadmill belt is worn out or not, lift the belt from one side and run your hand underneath its surface. If it feels rough and worn out from the underside, replace it with a new one, or else it may wear your deck rapidly.
Fixing the Problems With the Treadmill Motor
Apart from the treadmill belt, the next component of your treadmill that experiences a heavy workload is the treadmill motor. Thus, you may face various issues related to your motor as your treadmill gets older.
Treadmill Won’t Turn On/Off
If you are not able to power on/off your treadmill machine, then the fault may lie in the outlet that might have tripped off. Reset your power outlet and check if your treadmill is powered on.
If you observe that the outlet is working fine, then check the power is reaching the console.
If the console is not powered on, you should unplug the machine and remove the motor hood. Check for any unattached wires or loose pin connections.
If you see that all wires are properly attached, try to unplug and plug the plastic connectors. If this does not fix the issue, you should seek help from a qualified treadmill technician.
If you feel that your treadmill is not moving at a regular or smooth pace, the issue could be either electrical or mechanical. If the issue is mechanical, you should adjust the tension bolts or lubricate the treadmill belt.
If the issue seems to be electrical, you should remove the motor housing and inspect the plastic roller pulley and the drive belt.
If the drive belt fails to properly grip the roller, it may interfere with smooth power transfer and result in loss of speed.
If you smell of burning rubber, it may be due to the over-tight belt dragging through the treadmill deck. It results in excessive friction and hence produces a burning smell. You can fix this issue either by lubricating or loosening the belt.
If this is not the case, then check the motor housing after unplugging the machine. Replace any moving parts like pulley or drive belt if they are producing the smell.
Do Simple Treadmill Maintenance Checks
- Ensure to do regular cleaning of your treadmill. Use a vacuum cleaner for collecting the dust, debris, and pet hairs that may accumulate on the treadmill and enter its motor housing resulting in malfunctioning of motor components.
- Ensure to check and tighten the bolts and nuts every month so that they are fixed securely in their place.
- Every week check the walking belt and deck if there are any signs of wear and tear.
