AgateguyExplorerOct 27, 2016Onan 3600 lpHave a fault code reading 15 on an Onan LP 3600 and it says to drain the oil from the supply system. Any info on where to drain it?
MrWizardModeratorOct 30, 2016Oil in the supply systemThey are taking about oil in the l.p.This would mean disconnecting the l.p. Line, From the generator and cleaning/replacing the pressure/vapor regulatorIf that doesn't work, you will need to clean out the l.p. Tank and linesI would check with a propane distributor who services tanks etc..
