Finish Nailer Not Firing – Trigger Valve Replacement Fix

Why is My Porter Cable Nailer Not Firing?

If your Porter Cable nailer isn’t firing, there are a few potential reasons why. The most common reason is that the air compressor isn’t providing enough air pressure. Another possibility is that the nails are jammed in the nailer.

Lastly, the trigger mechanism could be damaged or defective. If you think the problem is with the air compressor, check to make sure that it’s turned on and plugged in properly. Also, check the gauge to see if it’s reading correctly.

If not, adjust accordingly. If there’s still no change, you may need a new air compressor. If you think the nails are jammed, take out the magazine and clear any debris that may be blocking them from moving freely.

Once cleared, try firing again. If that doesn’t work, disassemble the nailer according to your model’s instructions and look for any further obstructions inside. Lastly, if you think the trigger mechanism is damaged or defective, this will likely require replacement of part(s).

You can find replacement parts online or through a Porter Cable service center.
