What to Do if Air Compressor not Filling Tire

 Air Compressor not Filling Tire

Having a properly functioning air compressor is essential for maintaining optimal tire pressure. Besides, it also ensures safe and efficient driving. But facing a situation where your pump fails to fill a tire can be frustrating. This article explores potential solutions when an air pump refuses to fill a tire.

We will focus on some simple yet effective methods to fix this issue. We will consider the inspection of the pump and its components. You will learn to look for punctures, valve stem issues, or damaged rims.

By methodically assessing these factors and following the appropriate troubleshooting steps, you can increase your chances of identifying and rectifying the underlying cause of the air compressor not filling the tire.

Reasons Why Your Air Compressor not Working

An air compressor is a valuable tool. It provides compressed air for a wide range of applications. It can be from filling tires to powering pneumatic tools. But there are instances when an air compressor is not filling the tire. It can leave you puzzled and unable to carry out your intended tasks. This section will explore some general reasons why a pump may not be working.

Understanding the potential causes of pump malfunction is crucial for effective troubleshooting. Various factors can contribute to the problem. Those can be electrical issues, mechanical failures, or inadequate lubrication. Or there can be problems with the pressure switch or motor. Also, air intake filters, pressure relief valves, or hose issues can matter.

Troubleshooting these issues systematically will help restore the functionality of the pump. And it will enable you to resume your tasks efficiently.

Power Supply

The tire won't inflate due to power supply problems, so pay attention to this issue. 

Solution: Ensure the air pump is properly plugged in and gets an adequate power supply. Check the circuit breaker and reset it if necessary. If using an extension cord, ensure it's rated for the pump’s power requirements. Plug the tool directly into a dedicated outlet. Or use a heavy-duty extension cord if necessary.

Pressure Switch

The tire won't inflate due to the pressure switch problems. It controls the operation of the pump. It works by regulating the pressure levels. If the pressure switch is faulty, it can prevent the pump from starting desired pressure.

Solution when the tire won't inflate: Inspect the pressure switch for any visible damage. If necessary, replace the pressure switch with a new one. Do it according to the manufacturer's instructions.

Motor Problems

A malfunctioning motor can cause the air pump to fail to start or run intermittently. Motor issues can be attributed to electrical faults, worn-out brushes, or overheating.

Solution when the tire won't inflate: Check the motor connections, wiring, and brushes. Look for any signs of damage. Clean or replace the brushes if necessary. If the motor is overheating, ensure proper ventilation. And clean any obstructions around the motor.

Air Intake Filter

The reason the tire won't inflate may be a clogged or dirty air intake filter. It can restrict airflow. And it causes the pump to struggle or fail to start.

Solution: Regularly clean or replace the air intake filter to maintain optimal airflow. Refer to the pump’s manual for specific instructions on filter maintenance.

Lubrication Problems

Inadequate lubrication can lead to increased friction and wear on pump components. It results in poor performance or failure to start.

Solution for not working tyre inflator: Check the oil level in the pump’s crankcase. And add oil as needed. Follow the manufacturer's recommendations for the type and frequency of lubrication.


You can face the issue when the air compressor is not filling the tire due to air leaks. It can be in hoses, fittings, or valves. And this can reduce the pump's efficiency. And it prevents it from reaching the desired pressure.

Solution for not working tyre inflator: Inspect all connections, hoses, and fittings. Look for any leaks. Tighten loose connections or replace damaged parts as necessary. Apply thread sealant or Teflon tape to ensure proper sealing.

Damaged or Worn-out Components

Over time, various components of the air pump can become damaged or worn out.

Solution: Thoroughly inspect the pump for any signs of damage or wear on components. Replace faulty or worn-out parts with new ones according to the manufacturer's guidelines.

Incorrect Pressure Settings

You can also face the issue when the air compressor is not filling the tire due to incorrect pressure settings. This can prevent the pump from reaching the desired pressure. Or it causes it to shut off prematurely.

Solution when the tyre inflator not working: Adjust the pressure settings on the pump. Do it according to the recommended pressure. Use a pressure gauge to verify the accuracy of the pressure readings.

Remember always to consult the manufacturer's instructions and guidelines. If the issue persists or you are unsure about any repairs, seek professional help.

FAQ: What to Do if Air Compressor not Filling Tire

Why is my air compressor not building up pressure?

There can be several reasons your air compressor is not building up pressure. Some causes are:

  • Faulty pressure switches.
  • Air leaks.
  • Worn-out piston seals.
  • Clogged filters.
  • Inspecting and fixing these components is vital to identify and resolve the issue.

How long does it take for a compressor to build up pressure?

It depends on its size, capacity, and the desired pressure level. Smaller compressors with lower capacity may take a few minutes. At the same time, larger compressors may take longer. Factors like the condition of the compressor and the presence of any leaks affect the result.

What PSI should I set my air compressor to fill tires?

It depends on the specific tire and vehicle requirements. Refer to the vehicle's owner's manual to determine the correct PSI for your tires. It's important to set the air compressor to the recommended PSI. It ensures safe and optimal tire inflation. For this, use a tire pressure gauge. 

Can using an extension cord affect the performance of my air compressor in filling a tire?

Yes, using an inadequate extension cord can affect the performance of your air compressor. To ensure your air compressor works effectively when filling a tire, make sure the extension cord is rated for the pump's power requirements. It's often recommended to plug the compressor directly into a dedicated outlet or use a heavy-duty extension cord when necessary.

How can I prevent my air compressor from failing to fill a tire due to incorrect pressure settings?

Incorrect pressure settings can prevent your air compressor from filling a tire properly or cause it to shut off prematurely. To prevent this issue, adjust the pressure settings on your air compressor according to the recommended pressure for your specific tire and vehicle. Using a pressure gauge to verify the accuracy of the pressure readings can help ensure the right pressure level is reached during inflation. Always refer to the manufacturer's instructions for guidance.
