SOURCE: Onan 4000 RV Generator - where is the oil drain plug?

It should have a cover on the floor bottom that is held in place with two torx (star) screws. remove the cover and you can remove the plug with a 9/16 socket.

SOURCE: onan microlite 4000 generator no output

Hi, The 4000 rv unit unit is equipped with full diagnostics, and is indicated by the status light blinking. The blinking sequence, blinks a code as to the fault. If your unit runs and the status light is on without blinking, it is either the circuit breaker on the genset or in your distribution panel that needs to be reset. Good Luck, this should Fixya!

First locate the oil pressure switch and see if you can bypass it,then see if it runs. If not check the fuel filter and fuel pump,make sure solonoid for fuel pump is kicking on.

Starts runs for a minutes quits but if you keep pushing the start button it keeps running


You say Guardian that is Generac???? Then you indicate Onan 4.0KY. If it is a Onan and it stops after you release the button there are a couple of things. 1 st check the brushes, and polish the rotor slip rings, check the resisitance of the rotor, the electrical harness plugs are tight. The control requires a voltage feedback while cranking to engage the PCB run circuits, if all those check out you have a bad control board.

Check the rotor bruhes, slip rings are clean on the rotor. If you want to get deeper check and ohm the resisitance of the rotor, and stator both for continuity and ground shorts. Check plugs and wiring on control board. Failing that replace control board

Oil is being pulled from valve cover to air filter on my onan microquiet 4000 generator, what do I need to do?


63525c2e-e749-4a53-8402-d0463bb6c753.jpgThat sounds like the reed valve sticking or dirty.
You will need to take out the reed valve, clean and re-install. Be aware that a small amount of oil is common, also do not over fill the oil. The full mark is hot. Too much oil in the crakcase can build up pressure and keep the reed valve open.
