Standby Generac will not stay running
Posted on 8/30/21 at 9:23 am

Pville area -- It ran for an hour then stopped running. I waited an hour and tried starting it again -- it starts, then stops, then starts... 15kw -- air filter is dry -- proper oil level -- no error codes. HG board indicated it may not be getting enough gas due to other natural gas users in area -- no clue.
Prior homeowner has it set up where you can only start it manually if that matters.
Any ideas?

Do you have it routinely serviced? Mine test runs itself once a week to keep it functioning properly. Sounds like it was sitting up too long unused.

How old is it?
The newer Generac use a lot of plastic parts that break down easily from what I have seen.

If there are no error codes than it could be the gas supply.

May well be not enough gas due to everybody else using theirs

They all do this

is power surging when it is on?
more than likely its one of 2 issues
- lack of gas pressure
- stepping motor acting up which right now would be from lack of gas supply. later today it could be from overheating.
if its not raining, take the front cover off and make sure the lid stays open. Other than that, not much you can do.

Natural gas, like butane, is a bastard gas.

Yes on the service -- it does not come on automatically like most generators. Prior homeowner installed it to where you have to manually start it -- so I run it regularly.

Could be a faulty oil sensor. They stop on their own to prevent it locking up, but if the oil is good, the sensor could be bad.

Might be overheating?

Thx Slack -- I read that may be a possibility.

Not if his is turned to manual start only it won’t
Posted on 8/30/21 at 9:46 am to Laryngitis
if you are nto getting a fault I highly doubt its the oil sensor or overheating
is it surging some where the motor clearly ramps up and then back down without the electrical draw changing?

Unplug the oil sensor and see if it stays running. Mine went out on my 10kw portable. $100 part and Boone had may and online was all back order so I just left it unplugged just have to keep a check on the oil but doesn’t hurt it at all to run it

Any tips on locating the oil sensor?
777 -- no surging -- it starts, runs for about 10 secs, then stops -- then repeats.

oil sensor or a very very low gas pressure/trapped air in gas lines
really only things it can be.

It would take a LOT of generators to use up all the pressure from the supply...can't imagine that being it unless the main supply from company is operating below normal standard

This sounds like oil sensor.

very well could be main plant operating below but also many installs dont get the main regulator sized properly at the home and have issues with this.
