I am using my late husbands old air compressor but un able to fill tire the compressor comes on just runs and runs but no air could you please help me and have patience with this old woman and yes I really do not know what I am doing but I am trying thanks
Susan, there are many reasons why an air compressor will run but not build air pressure. That your Sears compressor is running but not building air is indicating that there is likely a mechanical issue with the pump, at least, that's the most prevalent.
If you wish to investigate further, please follow the troubleshooting link under Air Compressor Issues in the left nav bar, and see the page about air compressors that run but don't build pressure.
Cheers and good luck, and add a comment here if you have more to add.
