Predator Generator Repair

Predator generators are some of the best and most reliable power-generating units on the market today. They guarantee remarkable performance and are also readily affordable. However, like all engines that convert mechanical energy into electrical energy, Predator generators are not perfect. Something can unexpectedly go wrong with your generator that you may need to fix as soon as possible.

Predator Generator Troubleshooting


You can troubleshoot your Predator generator. Here are some of the issues you may likely experience with your power-generating unit:

Clogged air filter
You need to regularly clean or replace your air filters if you run your Predator generator in a dusty environment. A clogged filter can prevent the adequate ratio of fuel to air, which hinders the efficient operation of the generator. Never attempt running the generator without an air filter, as this will lead to permanent engine damage.

Fouled spark plugs
Fouled spark plugs have dark carbon deposits or sludge around them. Change the plugs when you see such accumulations and ensure the engine supplies electricity to the plug.

Loss of residual magnetism
This can happen if you leave your Predator generator unused for prolonged periods or when it runs with zero loads for far too long.

You can restore the magnetism by connecting the generator to a 12-volt battery. You can also plug in a drill and then use that drill’s motion to easily generate an electric current that quickly restores the magnetism in the generator.

Predator Generator DIY Repair


So, what if your Predator generator is running but is not supplying power to your home or workshop? You can do a few things to restore the power supply. Here’s a short video that explains what you can do if you find yourself in such a situation.

Another instance is if your Predator generator is not running. You may need to check the carburetor, the choke sticker or see if it has a cloaked fuel valve or dead battery. If you have low oil levels in the crankcase, the generator won’t start. You may need to top it up with the recommended engine oil for your Predator generator model. This video below explains what you can do if your Predator generator is not starting.

Your Predator generator could also be surging. One major reason behind this is that the float in the carb may be stuck. When this happens, it cuts off the fuel supply, causing your generator to surge.

Therefore, tap the side float bowl, and hopefully, this problem will be solved quickly. If not, flush the fuel bowl by opening the bowl drain and turning on the front panel fuel switch. Check the fuel line to ensure it is not plugged with debris. If it is, your generator will surge. Disconnect the fuel line and flush out the debris that clogs up the line. Other DIY repairs include changing fouled plugs and cleaning/replacing clogged filters, etc.

    Predator 8750 has a P999 code. I can’t find a description for this code anywhere. Habor Freight is no help.

    I bought my Predator 3500 inverter generator last summer (2022) and used it for the first time in January 2023.
    With no load on generator, it is drinking the fuel in 2 1/2 to 3 hrs. Why?
    I’ve seen generators like this one last more than 9 hrs on one 2.4 gallon tank.

    My predator 6500 has an electric cut off solenoid on the carburetor bowl but does Not have an electric start, and thus battery, or any battery in the system. So, I assume, yeah I know, the engine starts with the fuel in the bowl and gets power to open the solenoid, to let fuel flow, once the generator is running??? Help me understand please!

    Why is it so hard to find a repair service for this awesome Generator? What’s the problem? they sell them in all the Habor Freight stores, so why not have a repair place in the state?

    I bought a Predator 1400w generator just for emergency conditions. Not to run a house. Heater and a Light sorta.

    I bought it a year ago and the warranty is 90 days from purchase, go figure. First time out, I fill it and gas starts leaking out the bottom.

    It is the fuel petcock/ignition cutoff valve combo. Harbor freight, Amazon, Predator, ebay or the internet do no9t carry a parts list that I can find for the 1400 watt version.

    Is it time to get creative? I can get a inline fuel valve, but it does not have the long square shaft to screw in a knob. The square shaft also holds a plastic cog that pushes a micro switch to kill the generator “go” wiring.

    This can be modified to work for me, but why is there not a replacement valve? This is not a valve that screws into a tank, it is a inline valve.

    My Predator 9000 seems to have lost power output on one phase. The other phase works fine. It is only 2 years old and I only had to use it 3 times. I tried press all the circuit breakers on the unit and still nothing.
