Porter cable 20v brad nailer not firing mystery

I was right in the middle of a project last Saturday. I was adding trim to a new bookshelf in my shop. Everything was going great until my tool just quit. I pressed the nose down and pulled the trigger. There was no pop and no nail. It was just a dull click.

I have spent years using this Porter-Cable 20V brad nailer. I love that I do not need a loud air compressor or a messy hose. But these battery tools can be picky. If your nailer is acting up, do not worry yet. I found the best ways to get it working again.

Quick Fixes for a Stuck Nailer

Most of the time, the fix is very simple. I usually check three things first. These steps solve my issues nine times out of ten. I made a small chart to show you what to look for when you are stuck.

Common Problems and Easy Solutions

How I Clear a Hidden Jam

The most common reason for a Porter-Cable 20V brad nailer not firing is a jam. Sometimes you cannot even see the nail. A tiny piece of metal can stop the whole gun. I learned this the hard way after getting very frustrated one afternoon.

First, I always pull the battery out. I like to keep my fingers safe. Then I flip the silver latch on the front of the tool. This opens the jam door. I used a small probe to find a bent nail hiding in the track. Once I pulled it out, the gun worked perfectly.

Why the Lights Are Flashing

The two small lights on the base of the tool are very helpful. They are not just for seeing in dark corners. They are like a code. If my tool stops, I look at those LEDs right away to see what they say.

Reading the LED Light Codes

I used to think one bar on the battery was enough. I was wrong. This tool needs a lot of power to push a nail into hard wood. If the light blinks, just swap the battery. It is the fastest way to get back to your work.

Resetting the Internal Drive Blade

Sometimes you might hear a loud thud. This usually means the drive blade is stuck down. The blade is the part that hits the nail. If it does not retract, the gun will not fire again. It is a very common mechanical hiccup.

I fixed this by taking the battery out first. I opened the jam door on the nose. I used a flat head screwdriver to push the blade back up. You will hear a small click when it sits right. This reset my tool and I was back to nailing in seconds.

Cleaning the Safety Contact Trip

The nose of the gun is a safety switch. It must be pressed in to fire. In my dusty shop, sawdust gets inside the slide. If that part gets sticky, the gun thinks you are not pressing it against the wood.

I used a can of air to blow out the gunk. I made sure the nose could slide up and down easily. Do not use any oil on this part. Oil turns dust into a thick paste. A dry, clean tool is a happy tool that fires every time.

Using the Right Nails for the Job

I once bought cheap nails from a big bin. My Porter-Cable 20V brad nailer did not like them at all. They were a tiny bit too thick for the track. Now I only use high quality 18-gauge brad nails.

Make sure your nails are between 5/8 and 2 inches long. If they are too short, the feeder cannot grab them. If they are too long, they will jam the nose. Using the right nails keeps my projects moving along without any stops.

My Final Thoughts on This Tool

Fixing your own tools feels great. Most of the time, it is just a simple jam or a low battery. I hope these tips help you finish your project. There is nothing like the sound of a tool working the way it should.

I always keep my tool clean and my batteries full. This keeps me from getting stuck mid-job. If your motor is still silent after these steps, let me know. I can help you look at the trigger or the internal motor.
