How to troubleshoot inadequate fuel supply in Kohler 20RESB?
Check for damaged primary or secondary fuel regulators, loose connections to the fuel solenoid valve, a damaged or closed fuel shutoff valve, an empty LP fuel tank, or other problems with the fuel supply. Check the fuel supply pressure to the generator set.
Why is my Kohler Portable Generator cranking but not starting properly?
If your Kohler Portable Generator cranks but struggles to start, lacks power, or runs erratically, several factors could be at play. A clogged air cleaner can restrict airflow, so try cleaning or replacing it. Weak battery or poor battery connections can also cause these issues; recharge/replace the battery and ensure connections are clean and tight. Inspect the spark plug wires for secure connections. Insufficient fuel pressure could be the culprit, so verify the fuel supply and valves. Also, check the oil level and add oil if necessary, in case of a low oil pressure shutdown. If these steps don't resolve the problem, it might be due to engine malfunction, in which case you should contact an authorized Kohler distributor/dealer.
What to do if my Kohler 20RESB does not crank?
If your Kohler Portable Generator isn't cranking, the issue could stem from several causes. First, check the battery; it might be weak or dead, requiring a recharge or replacement. Ensure the battery connections are correct and secure. If a fault shutdown occurred, check the controller display for fault messages and reset the controller after correcting the fault. Also, confirm the generator set is in the RUN or AUTO mode. Finally, check if the generator thermostat tripped and reset it.
How to fix no AC output on my Kohler 20RESB Portable Generator?
If your Kohler Portable Generator has no AC output, start by checking the line circuit breaker to ensure it's in the ON position. If the breaker tripped, it might be due to an overload; reduce the load on the generator. If the breaker trips due to a short circuit or if the auxiliary winding circuit breaker tripped, contact an authorized Kohler distributor/dealer for service. If the auxiliary winding circuit breaker trips repeatedly, also contact an authorized Kohler distributor/dealer for service.
What to do if my Kohler 20RESB Portable Generator stops suddenly?
If your Kohler Portable Generator suddenly stops, several factors could be responsible. Check for low oil pressure shutdown by looking for oil leaks and verifying the oil level. Ensure the generator isn't out of fuel. If an overcrank shutdown occurred, reset the controller. Also, check the controller display for fault messages, correct the fault condition, and reset the controller. Make sure the generator set is in the RUN or AUTO mode. Check the remote switch position or OnCue Plus in case of a remote stop command. If the auxiliary winding circuit breaker tripped, reset it. If the breaker trips repeatedly or if there is an engine malfunction, contact an authorized Kohler distributor/dealer.
Why does my Kohler Portable Generator have low output voltage?
If your Kohler Portable Generator has low output or experiences an excessive voltage drop, it might be overloaded. Try reducing the load on the generator set.
Why is the controller display off on my Kohler 20RESB Portable Generator?
If the controller display on your Kohler Portable Generator is off, the cause might be low or no battery voltage. Check the connections and the generator set battery.
Why is the backlight off on my Kohler 20RESB's controller display?
The backlight on the Kohler Portable Generator controller display turns off after about 1 minute of inactivity. The backlight will turn on when a button is pressed or the generator set starts.
What to do if the breaker will not close in RUN on my Kohler 20RESB?
If the breaker won't close in RUN on your Kohler Portable Generator, it could be due to: another breaker being closed (stop the other generator set), auto-discovery not being complete (initiate auto-discovery by ensuring this generator is in RUN mode and the other is stopped with the controller in OFF mode), or bus sensing not being connected correctly (check wiring between both generators and the Automatic Paralleling Module).
Why does SiteTech indicate that both engines are under load, but the ATS has not transferred on my Kohler 20RESB Portable Generator?
If SiteTech indicates that both engines are under load but the ATS hasn't transferred on your Kohler Portable Generator, it could be due to the metering on either generator being backwards. To fix this, select a different model number for the affected generator, then re-select the correct model number. This clears the CT direction flag and allows the generators to re-determine CT direction.
