Common Wheelchair Faults

Like any other equipment, the wheelchair faces faults and problems over time. It can be a fault in its upholstery no matter what material is used in the manufacturing. Many users face wear and tear and malfunction in their electrical systems. 

So, it means you and I are not alone in facing such errors and faults in our wheelchairs. It is normal for every other wheelchair owner. 

Here we will explore some of the most common wheelchair faults you may encounter. Along with tips on how to identify, troubleshoot, and potentially fix these issues.

Wheelchair Faults and Solutions

Below are the most common electric wheelchair problems that most users face in their wheelchairs. Further, we will discuss the most practical solutions for fixing these faults. 

1. Seat Upholstery Damage and How to Deal 

Your wheelchair’s seat and backrest are like your favorite couch – they should be comfy and look good. But sometimes, these soft parts can get damaged. It is the most common issue faced by everyone. 

A damaged upholstery causes a sitting problem, especially for someone who spends most of their time in their wheelchair. The seat of the wheelchair becomes flattened and its natural shape is lost. Ultimately it becomes very uncomfortable for you to sit on it for a shorter period of time. A worn seat cushion leads to pressure sores for the user.

Let’s look at why this happens and how to fix it.

Why Does Upholstery Get Damaged?

The constant use of a wheelchair could be the reason for your damaged upholstery. It may be because of;

• Daily Wear and Tear: Just like your favorite jeans, wheelchair upholstery can wear out from everyday use.
• Sun Damage: Too much sunlight can make the fabric fade and become weak.
• Tears and Rips: Sharp objects or rough edges can cause cuts in the material. 

How to Fix Upholstery Problems

The first of you should take care of your wheelchair upholstery. You should maintain its cleanliness. Regularly clean it using a soft brush and remove its dirt. If you see small tears in it fix them immediately to avoid more damage. You can use fabric patches or repair tape to do this process. 

Further, you should park your wheelchair in a shaded place to avoid direct contact with sunlight. It will allow it to live long and avoid getting weak and fragile. And you can use a cushion cover to hide damage and add extra comfort. 

If you think it has already gone and could not be fixed for further use. Then it will be wise to replace it with a new one. I suggest you buy a new one from the manufacturer to avoid fitting and size issues. Another option is to get in touch with vendors and take their suggestions for replacement. 

2. Wheel Problems and How to Tackle Them

Wheelchair users often face problems with their chair’s wheels. These issues can make it hard to move around and stay safe. Let’s look at some common wheel problems and how to fix wheelchair wheels.

2. 1 Wheel Misalignment

When wheels are not lined up right, it can cause:

• The chair pulled to one side
• Uneven tire wear
• Harder to push or steer the chair
• More effort needed to move

This problem directly affects the smooth maneuverability of the wheelchair. Your wheelchair wheels veer to one side and make it difficult to move in your desired direction. 

Solution:

• Check if the caster (front) wheels are straight
• Make sure the rear wheels are at the same angle
• Tighten any loose nuts or bolts

If you’re not sure how to fix it, ask a wheelchair repair shop for help

2.2 Squeaky Wheels

Squeaky wheels are not just annoying. They can mean:

• Wheel bearings need oil
• Axles are dirty or damaged
• Parts are loose or worn out

Solution:

• Clean the wheels, bearings, and axles
• Use a light oil made for wheelchairs on the moving parts
• Check if any parts are loose and tighten them
• If the noise doesn’t stop, you might need new bearings or wheels

2.3 Wheel Locks Failure (Brake Malfunction)

Wheel locks are for your safety because they keep the wheelchair stationary when not in use. Your failure of the wheel locks may pose a safety hazard for you. You may struggle to stop it when you need it. 

When wheel locks (also called brakes) don’t work well:

• The chair might roll when you don’t want it to
• It’s harder to get in and out of the chair safely
• You might slide on slopes

Solution:

• Check if the locks are touching the wheels properly
• Tighten any loose parts
• Clean the tire surface where the locks touch
• If the locks are worn out, replace them
• Make sure your tires are inflated right (if they’re air-filled)

2.4 Flat or Worn-Out Tires

Tires that are flat or worn out can cause:

• A bumpy, uncomfortable ride
• Poor grip on different surfaces
• More effort is needed to move the chair

Solution:

For air-filled tires:

• Check tire pressure regularly and add air if needed
• Look for punctures and patch them
• Replace the tire if it’s very worn or damaged

For solid tires:

• Check for cracks or chunks missing
• Replace the tire if it’s worn down or damaged

3. Battery Problems

If you use an electric wheelchair, the battery is like its heartbeat. You cannot travel in your wheelchair for a longer time if it is not working right. Let’s look at common battery problems and how to fix them.

• Battery drainage is a common problem you can face in your electric wheelchair. It causes unexpected or sudden loss of power. 
• You can face charging problems where your chair battery would not hold the charge due to a faulty charging mechanism. The reason could be with your charging adaptor or wheelchair battery. 
• Wheelchair batteries may start losing their capacity over time. It results in limited battery life and shorter usage time. 
• If your wheelchair won’t turn on at all. Then it might relate to your wheelchair battery. 

Before addressing the fixes of these problems you must ensure there is a battery problem. If you face these troubles all the time then your battery might be old and lose storage capacity. Extreme weather changes like too much heat or cold also affect battery performance. 

Fixing Battery Issues

Here are the solutions to deal with these battery faults. First of all, it is crucial to monitor your battery health regularly and follow the manufacturer’s guidelines to charge it. 

Avoid overcharging or letting it drain the power completely. Because it can shorten the lifespan of the battery. Fully charge it during the night. 

Whenever you charge the battery make sure it is plugged properly and look for any damage in the cord. You can also try different outlets to tackle the problem. 

Sometimes the battery terminals get rusty and interrupt the charging mechanism. So, turn off the chair and clean the terminal with a dry cloth. After this make sure the connections are tight. 

Don’t park the wheelchair in too hot or cold places. Avoid leaving it in direct sunlight for a long time. 

Get a Check-Up:

If problems continue, ask a wheelchair technician to test your battery. They can tell you if it’s time for a new one.

Preventing Future Problems

• Charge your battery regularly, even if you don’t use the chair every day.
• Keep your chair clean and dry.
• Follow the manufacturer’s instructions for battery care.
• Get your wheelchair serviced once a year.

4. Joystick or Electrical Components Malfunction 

Your power wheelchair is like a mini-car with lots of electrical parts. Sometimes, these parts can act up, causing your chair to behave strangely. Let’s explore what can go wrong with these electrical components and how to get them back on track.

Imagine you’re ready to head out, but your joystick doesn’t respond. Or maybe your chair moves in jerky motions, or the lights flicker on and off. These are signs that your chair’s electrical system needs some attention. The control panel might show error codes, or buttons might stop working. Sometimes, the chair might even move on its own. 

Reason: 

• The electrical parts can wear out over time. 
• The dust, dirt, or moisture can sneak into the controls and cause trouble.  
• Sometimes, wires can be lost or damaged. 
• Even bumping into things too hard can shake up the delicate electronics inside your chair.

Solving the Electrical Components

First things first, don’t panic! Many electrical issues can be fixed easily. 

Start by checking that everything is plugged in properly and that no wires are visibly damaged. If your chair has a power-save mode, try turning it off and on again – sometimes this simple trick can reset minor glitches.

If you are facing a sticky joystick then try cleaning around the base with a dry cloth. Also, clean the buttons gently if they are not working properly. This simple procedure helps to remove the dust that could be the reason for the joystick malfunction. 

If the problem persists. Then it would be wise to contact the wheelchair technician. Because you can damage these delicate parts of a wheelchair. The expert will diagnose the issue and help you fix the issues safely. He will also suggest whether you need to replace them with newer ones. 

5. Motor Malfunction

The motor is the muscle of your power wheelchair, giving it the strength to move. You may face problems with your wheelchair motor.

• Your wheelchair struggles to move on a small slope. 
• The wheelchair motor starts to produce strange noises like grinding or whining. 
• Chair jerk or hesitate when you start moving. 

This could happen because the wheelchair motor is the main part that works hard to move the chair and can wear out over time. Sometimes, the brushes inside the motor (small parts that help it turn) get worn down. Overheating can also make motors cranky, especially if you often carry heavy loads or climb uphill often.

Solving Motor Issues

Dealing with the motor issue is not as simple. You might need these skills and tools to handle the problem. Look for the below solutions to resolve the issue. If you still facing the problem then call the wheelchair technician. 

• First, give your chair a quick once-over. Remove if anything is tangled in the wheels. Because it can put extra strain on the motor. Ultimately more energy is consumed to move the chair.
• If your chair has a freewheel mode, try switching it on and off a few times – this can sometimes reset minor glitches.

If the motor produces noise. Then carefully listen to pinpoint where the sound is coming from. A grinding noise might mean something is loose, while a high-pitched whine could signal worn brushes. 

6. Foldable Frame Stiffness

If you have a folding wheelchair, you know how handy it can be for storage and travel. For foldable wheelchairs, stiffness in the frame can make it difficult to fold and unfold the wheelchair for transport or storage. But what happens when your chair starts acting like it doesn’t want to fold anymore? 

• Wheelchair starts feeling stuck and produces a creaking noise when trying to fold or unfold it. 
• The frame does not open up fully or refuses to close properly. 

How to Solve Frame Problem

When your wheelchair would not fold or unfold then try the below fixes to deal with the frame stiffness. 

• Clean the wheelchair properly in the folding joints and remove dust from these areas. You can use a soft brush to remove the dirt and debris. 
• Try using the lubricant on the moving parts. Most of the time this simple method can help for the smooth folding and unfolding of the wheelchair frame.  
• Check for any loose screws and bolts and tighten them gently. 
• Make sure you are folding or unfolding the chair with the right technique. Different chairs have different folding mechanisms. Read the wheelchair manual to understand the right process. 

Regularly lubricating the folding parts (about once a month) can help keep everything moving smoothly. When you’re not using your chair, try to store it in its unfolded position to reduce strain on the joints.

7. Replacement Parts 

The wheelchair has many parts. Over time, some of these parts might wear out or break. When this happens, you’ll need to replace them to keep your chair running smoothly. 

It is the most daunting task for most users to find the right replacement part for their specific wheelchair model. The common parts that you might need to replace for a wheelchair are;

• Wheels and tires are often the first things to show wear. You might notice your tires looking flat or your wheels wobbling.
