I have a Parallax 7345 converter

thanks in advance for your help

Loose connections in RV's are a real problem, unplug, and shut off generator and then go chasing loose screws in transfer switch, breaker panel, etc.

so what was the problem? Has it been solved yet?

Once when I had the same trouble as the OP, it turned out the power cord was loose where it connected to the coach in a junction box. The junction box was located at the back of the compartment where the power cord is stored. Apparently, when putting the power cord in and out of the compartment, the wire nuts inside the junction box were loosened. Easy fix.

transfer switch. had the same problem a few years ago. called and got a new board, simple to replace.

I had that happen a while back. The plug to the power converter came loose. Easy fixes are the best!!

We had a similar problem years ago and it was just a loose screw in the transfer switch.

Sometimes a good thump or poking at it after opening it up (obviously with all power removed) can unstick them. It still probably should be replaced as I suspect it's not likely to keep working well for too much longer once it's been stuck once.

Most 30A transfer switches use a single big double-throw double-pole relay/contactor, with some sort of time delay circuit on the switch over to generator power. The shore power is the normally closed circuit, and the generator the normally open one that gets closed after the time delay. Contacts that get too hot (due to wear or arcing) can weld themselves together and keep it from switching back properly, and this is one common source of sticking; to a large extent, this sort of damage can be avoided by not switching under (heavy) load.

Edit: Also check that the connections between the power cord inlet and the transfer switch haven't worked loose. It may be as simple as a screw that needs tightening or a wire nut that needs re-nutting.

Plus - Any power at the pedestal? Could also be plug/cord etc to the transfer switch.

Possible GFI reset

The converter has nothing to do with the 120VAC side.

Transfer switch.

Make sure you twist the body of the twist lock cord before you twist the retaining ring. That twist lock cord is sensitive to full engagement.
