Generac generator won't stay running	doug	8-15-07
I recently bought a used Lance camper equipped with a Generac np34lp gas generator with less than 100 hrs. The unit will not stay running. Sometimes the unit would run for and couple of hours now after a certified Generac repair shop had it for 30 plus days, 22 hrs of labor and countless hours with Generac tech support it runs 2 to 12 minutes or worse than before. The repair facility is up front and stated that they've seen this model have the same problems and that it's non repairable. Generac recommended to them to just get it back to the customer but the repair shop wouldn't release the rv for less than $750. So I had to pay $750 for parts and labor to get my rv released and for a generator thats worse than before. I see from this web sight these generators have been a very common problem and it smells like a class act lemon suite. Anyone whom can help me or is interested please reply. Thanks for reading this!

I bought a 2000 Northland Camper with a LP Generac Generator. The generator broke annually with very little use. Lately I took it into the shop and they say it looks like it was defective from the beginning and that is why boards keep burning up on it. They are recommending that I install a new one and be rid of this one. Is there a lemon law on this sort of thing? I believe I paid about 3k for this thing and probably another 1k in repairs.

GENERAC 4000 GENERATOR...VERY LOW HOURS...STARTS RUNS WELL AND AFTER 15-20 SECONDS SHUTS OFF.FUEL GOOD,CARB GOOD,BATT GOOD... I AM A GOOD MECHANIC...BUT THIS HAS ME STUMPTED...COULD IT BE A BAD BOARD(APPX 1" BY 1")?..OR BAD OIL LOW SWITCH..?
Re: Generac generator won't stay running	richard knouse	8-19-07
Ours wouldn't keep running. The vibration caused the low oil shut off switch to activate. This kept shutting off the fuel. Rich

Doug, I have a coach with a Generac gas generator and all I can tell you is that you cant find assistance or any good qualified mechanics with knowledge. I've had nothing but problems, and mine has only 450 hours on it. I had a problem with it running after shutting off (dieseling) and no person I spoke with in the US had any knowledge of this problem. Out of frustration I purchased a ned carb from orderterr, and low and behold it was a replacement model with an electric solenoid in the bottom. Bingo, no more run on!!! They had an upgrade but would not tell anyone probably in fear of a suit. I just came back from a trip and the exhaust valve siezed in the head, so I'm currently fixing that myself. Good Luck!

Re: Generac generator won't stay running	Joe T. Jones	9-2-07
I have a Generac generator in my motor home and it has never run right. It has been in the shop most all of its life and is now out of warranty and only has 60 hours of operating time, most in the shops. I have had it to two Generac mechanics and they think the have it fixed and I take it out and it runs worse than before. They have replaced the boards, fuel pump and the carburetor. We have cut out the whole floor of the generator compartment and still no help. Generac is aware of the problem and does not admit that it exists. I am fed up with Generac and I am ready for a different brand.

If your still looking for manuals for your Generac NP-52g model 9202 go this this web site http://www.guardiangenerators.com/Products/Recreation/Manual.aspx and look only for the "NP" element of "Generac NP-52g model 9202" rediculously buried in their site. Information their search feature returns zero results found but it's all there.
Re: Generac generator won't stay running	dave	10-8-08
When will people ever learn??? every thing generac makes is simply JUNK! get it? wake up people, you might as well buy chinese junk, the only benefit is that its cheaper (and likely more reliable) but, be smart and buy a good name like Onan
Re spark plug fires one time	johnnie	8-23-08
My impact would not start, so I pulled the spark plug out and, found it would spark only one time. I would let off the switch and try it again and, every time I did the plug, sparks only one time.
Re: Generac generator won't stay running	Norman L. Ward	8-15-08
I have a generac generator for home use, and the gas tank was empty, I put more gas in it and it will run for 2 seconds and shut off. I can restart the generator and it will only run for 2 seconds. I have installed a new fuel filter, and cleaner the carburetor about twelve times, and the problem still exit. Please help.
Re: Generac generator won't stay running	dwight	8-2-08
My generac in my lance(2002) 1121 just stared to have problems, i was talking to a guy that works on them and he said if you undo a gass line by the generator and turn it down there will be oil that coems out..(i did it and have oil in the lines) and it wont stay running he told me that the oil is in the the lp bottle and when the guy at the fuling place puts to much gas in the tank it causes the oil to vaperize and when it gets through the regulator it condenses an collects in the lines and plugs the carb and the regulator. and that is where the problem starts. i am going to take mine apart and clean the carb and the regulator. I WILL LET YOU KNOW HOW IT TURNS OUT.. ARIZONA

Re: Generac generator won't stay running	Ron Orbin	8-16-07
Sorry about the typo's. That was a "new carb from Ordertree" They have been very accurate and speedy with all the parts I have purchased from them. Good luck
Re: Generac generator won't stay running	Keith Charles	3-20-08
Hi, I'm having the same trouble can you tell me where you bought the carb from? Thanks Keith
Re: impact 34 geneator by generac will not produce output power	Bob	8-13-08
Go online to guardian. Click on the rv tab, then go to left side and should find manuals. click and go to the page and scroll to repair and should get to CCRV and impact. They are free to download. Generac is the only company to give them free. Bob
Re: Generac generator won't stay running	Ray	9-2-08
Anyone know of a repair shop for I have a Generac NP52G. I know it has a bad Starter contactor (SC) because I can by pass it and start the generator. But it will not stay running.
Re: Generac generator won't stay running	Bob	8-13-08
That style coil is unforgiving. It will fail if you crank the engine over with the spark plug wires off. I believe the coil is obsolete. I have used an onan coil on kohler gen sets but have not tried it on the older generac units. Last I had seen the old generac coil was over $200 before it was obsoleted. There is also a spark unit that plugs in near the coil and those go bad also. Bob
Re: impact 34 geneator by generac will not produce output power	jacob	9-10-08
Have a generac impact 34 that runs until a load is placed on it. Need help or service manual. Thanks
Re: Generac generator won't stay running	john	8-24-08
I have found the start switch has a contact problem. If you hold the switch to the start position and it starts and then let it go to the middle position (run position) and then it dies. Try holding the switch to toward the start position but not all the way down. If it tries to stay running it may be the switch. I am replacing it on my NP-30-G model. I'll let you know.
