THere are many ways Converters fail. the WFCO's have a favorite mode and you have NOT described it at all. Just so you know but other failures are possible.
OPNspaces did a good job of covering most of them.. And I do not think the only one left is possible with your WFCO But It is with my Progressive Dynamics
(It is a plug in model with a cord and plug that plugs into an outlet.. I suspect you can guess that from time to time I snag the cord and unplug it).
If the unit needs to be replaced.. Progressive Dynamics is the way to go in my opinion They are simply the best. Period.
