Compressor Will Not Start

Compressor will not start:

One of the most frustrating things to the home handyperson is when a tool doesn't work properly. Most of us just want to use our home air compressors, we don't necessarily want to know how they work or have to fix them.

You are not alone if that is the case.

On this page immediately below is a form that you can use to ask a question about what to do when your compressor will not start.

I ask that you please scroll to the bottom of this page (below the form) and see all the questions and answers already posted about this subject, as I suspect that you will find that someone else has already written in about what you are experiencing.

Here is a page that lists the common reasons why a compressor will not start.

If no answer is found, fill in the form and we'll see if we can help.

And, if you've got a suggestion about solving the "compressor will not start" problem, also please use the form to help someone else.
