20 kw, 2008, model 057440, propane set up.
The maintenance light came on a while back. I reset all the maintenance in the menu. Couple hours later it was back on. rechecked maintenance. I cleared them all again. I did put a brand new battery in. it was showing 13.7 volts. No matter how many times I clear the reset maintenance the light keeps coming back on. it will show inspect air filter, inspect spark plugs and goes right through them all. Tried resetting each and still comes back on. Has anyone else had this issue.

The unit runs fine and does its weekly start and works fine during any outage.

Those units would do that from time to time, my guess is replacing the digital control is your only fix. You may rey totally unplugging the controller and then rebooting it.

Thanks. I will try disconnecting the battery and taking out the fuse, then unplug all the connectors. rehook everything and see if that does it. although I did undo the battery and the fuse when i replaced the battery.
