Question about Watts Onan Portable Generator - 4000 , Model# 5500

1 Answer

My Onan Emerald Plus Gen, 5.0 BGE-FA, will start and run normally for 5-10 min, then will start surging, and then die after about 20 seconds. This is with or without load. I changed the oil/filter and air filter last fall.

check for a faulty sump oil switch . check for faulty coil ( magneto on the flywheel) as the time it runs suggests that it is breaking down internally.

Onan 2800 generator sops when a/c is turn on


While you didn't indicate the btus of the HVAC I assume it worked before? What you are describing sounds like the engine isn't making horsepwer. A 2800 is a small unit that a HVAC and some lights is about all it can stand. The HVAC takes about 6 x current to start it, than it does to run it. If this inrush is high and the generator engine isn't producing full HP then it will shut off and die on under frequency. I would recommend having and engine leakdown test done (not a compression test, as that doesn't tell the whole story. This will ensure all valves and rings are mechanincally in good shape, then try a basix tune up, plugs filters etc.

More likely the switch is bad, and only make run contact when in the start position.
Easy to test the switch continuity with a ohm meter when it is not running.
