WFCO converters are known to have a high failure rate.. From others it is one fairly easily replaced part but I have no idea which (others might but are they reading this thread)
I suggest a Progressive Dynamics 9245 as the replacement for that one.
I have yet to find a better converter. Found a couple as good but none better than the Progressive Dynamics Wizard controlled units.
Optional Dongle
Alternative is the PD 9145 with charge wizard dongle (Sometime the 91-- pair will be cheaper but with the wizard dongle it is the same as the 92-- with dongle)
