    You have one of two choices, take it apart and fix it or return it for warranty work.

    Try cleaning it, maybe there’s pocket fluff in there.

    Misaligned track, broken spring, disconnected spring, lint in the switch. Could be a dozen things, without having it in hand, without disassembly and without information on what brand and model it is, that's like asking "My browser won't connect? What's wrong with my internet?" it's way too vague to offer any meaningful help.

    What brand OTF?
    Im no otf pro, but it sounds like what you are describing is that you still have spring pressure but a failure to fire when the slide switch is in its fire position (slid forward).
    Sounds like your bottom release gate (tab) is not being moved out of the way allowing the blade to release. There could be a number of problems causing this, but the first two (and most simple to fix) are that there is simply crud, pocket lint inside your knife or the screws have become loose.
    Make sure all screws are tight and flush your knife with naptha or lighter fluid. If the problem still persists, the fixes get more complicated and you may have to send it in to the manufacture.

    I used Hoppes Blast&Shine to clean my OTF knives, when they become somewhat sticky.
    Just shoot some inside and give it a try, not implying it is your problem but it's worth trying as it won't hurt anything already broke.

    Take it apart and have a look. There's really not much to them.

    Try to reassamble it, if it still fails toss it and get a new one.

    Clean it. If that doesn't work, take it apart, inspect, and clean. If still broke, landfill it.

    try zippo lighter fluid or naphtha. fill it up in a safe environment.....shake it well and drain out and redo until it comes out clean. dont be dumb and try doing it while smoking or near a heat source. use common sense please.

    the lighter fluid evaporates fairly quickly and leaves a bit of lubrication. too much lubrication is a otf killer. this is what the otf and auto guys always recommend first before tinkering and such.

    if that doesnt work it could be many other things. these things are pretty simple and usually dont break. good luck.
