Fenix Flashlight Troubleshooting Guide

LOOSE SWITCH
The #1 service call
we receive concerningFenix flashlights is a loose silver o-ring in the tailcap.  If your light works intermittently or if the LED goes on and off, more than likely it is a loose o-ring in the tailcaop.

Follow these steps to troubleshoot:

1.  Remove the tailcap
2.  Look on the inside of the tailcap and you may see a silver o-ring with two little indentions in it.
3.  Take a spanner wrench or needle-nose pliers and place the tips in the little indentions in the silver o-ring in the tailcap.  
4.  Turn COUNTER CLOCKWISE.  If the ring is loose any, that can cause your light to not work properly.
5.  IMPORTANT:  Do not put Loctite glue (or such) on the o-ring.  To replace the switch in the tailcap, you have to be able to removed this ring to access the switch.
6.  It's a good idea to periodically check to make sure it is secure.  With the clicking on and off of your light, that ring can work loose.  

NOTE:  NOT ALL FENIX FLASHLIGHTS HAVE THE SILVER O-RING AS IN THE PHOTO. FOLLOW THE ABOVE STEPS IF YOUR LIGHT HAS THE TYPE OF O-RING IN THE PHOTO BELOW.

LIGHT WON'T COME ON

This applies to all the lights which have a removable head and tailcap.  For example, PD35, UC35, PD32, etc. If you ever take your flashlight apart to clean it and you get the tailcap and the head reversed, your light won't come on. Some people also swap the ends so that the pocket clip is in the direction they want it.  That causes the light not to work anymore.  Below is the correct placement for the head and tailcap. Please pay attention to the direction the pocket clip is pointing.

GENERAL MAINTENANCE
If you're having trouble with your Fenix LED flashlight, don't panic. Fenix products are built tough, and often times the issues are incredibly easy to fix. We'll walk you through some easy troubleshooting tips to help you diagnose and resolve your issues. If your Fenix flashlight stops working, take the following measures:

For starters, double-check your power-source. It seems silly, but everyone has found themselves stumped by an electronic issue when the problem turns out to be dead batteries. Replace the existing cells with batteries you know are fresh, and see if the problem persists.

If the light is still not working, then clean out the components with the proper materials and

techniques. Cleaning your flashlight regularly is an excellent way to maintain top performance. You'll need some cotten swabs, O-ring lube, and rubbing alcohol to properly clean your flashlight. By ensuring the light and all of its contacts are clean, you will ensure the issue is not caused by corossion or by putting it together improperly. you can see a step-by-step video of how to properly clean your light here.

To diagnose this issue, you can bypass the switch and make contact directly with the battery. if the light turns up when bypassing the switch, you'll know that the problem is somewhere in the circuitry of the button. You can learn how to diagnose this issue here.

 

 

 

While we're on the topic of switches, you may also want to replace the boot cap of your fenix flashlight. Different color options and textures are available for some lights. Learn more about replacing your flashlight's tailcap boot here.
