Question about Generac Power Systems Generac 5522 14 Kw AirCooled Standby Generator

1 Answer

I purchased a new Generac 20 KW air cooled standby generator. It shuts down under its excercise program and lists a low voltage fault code. I can start the unit in the manual mode and it starts and runs just fine. Any ideas. The units is under warrenty but the closest authorized dealer is two hours away.

Under warranty , you best have to wait the time as anything you do to fix it will void the warranty which will suit the service agent just fine
if you void the warranty he will get 2 hours travelling time plus the cost to repair time so don't touch it

fuse are meant to protect the costlier part of the machine thereby damaging itself.  there is probably overloading of your circuit. call the electrician and find the actual power required by your house.  there is a possibility of having a short circuit in your generator. your local electrician can check it.

Make sure that the throttle linkage is all there and not damaged/misadjusted, then get a manometer and check your inlet gas pressure. Gas pressure should be 8 inches of water column and stay there running or not.

SOURCE: Attempted to start Generac Guardian 15 kw air

I work on these every day. Its either gonna be the rotor or stater, the voltage regulator, but most likely its a bad stepper motor which is the throttle motor, or control board. Thats all that could be causing that so its one of those. If its the rotor or stater thats bad it causes the generator to RPM up because it thinks its not producing enough power due to that. I had the same problem with the same one we just fixed and it was the slip rings on the end of the rotor so bad rotor.

Hi 'Phil. the biggest problem with generators is that they sit with fuel in the carburator for long periods of time. This always gums up the carburator. From the sounds of yours, you can start by adding carb. cleaner to your fuel but in the end you may have to replace or rebuild your carburator. Joe

Thanks for choosing Fixya!

Hello i just started my 8 kw hole house generater ran greatput my electric water heater on 26 amp draw andsmoke came out exhaust vent shut it down ran again great turned only heater on again took amp


8 kW has a 35 amp breaker on the unit. A typical hot water is 4500 watts at 240 volts = 18.75 amps on each leg. If you are measuring 26 on one side and 19 on the other it should be ok. If it is shutting down you may have a fuel problem or you may need to adjust voltage if it's too low. Which model of 8 kW is it?

Engine will turn over/crank but will not run


All internal combustion engines have the same requirements. They must have the correct air fuel mixture and source of ignition in order to run. Although I am unfamiliar with the system you have, the fact thst it will start without the air filter but won't with the air filter indicates that you either have a dirty air filter (you said yours was clean) or you have too much fuel entering the combustion chamber. Beyond that I would only be guessing the reason (air fuel mixture regulator, worn jet, wrong size jet, something else bocking air flow etc.)

Under voltage alarm /shutdown on generac 10 kw gen.


The brushes on Generac automatic units are most likely not lined up with the slip rings and will wear down and burn out very fast. There is no way of checking this during assenbly because they are hidden from view and the generator has to be dismantled to be able to replace them. It's an extremely poor design and Genrac should face a class action lawsuit for producing this piece of junk.

Generac Guardian 12 KW Model 04456-2 shuts down on overspeed in cold weather


Leigh,
See my 5/22/12 comments on my "overspeed fault" problem resolution [Generac 43903 standby Generator overspeed indicator on starting] . If it only runs for a few seconds and then quits, you may have a similar condition to the one my unit had. A good technician should be able to diagnose the problem and determine if you have a similar failure to the one I had, or one of the other causes suggested by RSG000.

The battery could be bad. Try to measure the battery voltage when you try to start. If the battery is bad then the voltage will drop quite low when the battery is loaded with trying to start the set. If you can borrow a similar battery you could just try with it.

2 bolts on top of the front panel. Take them out and then just puul up and it come off. you can then easily remove the battery but make sure the leads dont touch as they still have charger power running through them.
