Problem with Progressive Industries HW50C built in Surge

I'm having problems with my built in Progressive Industries HW50C. When I apply either 50A or 30A to my trailer the remote control shows no errors but well not let power through. The power is coming from my shop that I wired and have both 30 and 50 available. I have over the years had 4 other RVs plugged into this 2 service plugs. The remote control shows no errors.

So I plugged in my Surge Guard 34830 Portable RV Surge Protector With LCD Display- 30 Amp into the outlet and let it go through its cycle and after about 2 minutes the remote surge protector allowed power to the trailer. No errors on external also. Went into the trailer and switched to remote and everything is working.

A couple of days ago I turned it on with just the built in surge protector and it did the same thing so I used the bypass switch on the remote and I heard it thunk and then put it back to normal and it worked. I would not have switched to bypass at any campground but I know my power is good. Tonight when I turned power onto the trailer it wouldn't let it go through again tried the bypass and heard the thunk from box and had power but when I turned it back to normal it again would not allow power.

This unit is in a trailer that is about 6 months old and it was a brand new unit.

Any thoughts before I call PI which I hope to have a chance to tomorrow.

I was planning to not carry my 30A external but now I think it well have a place in the trailer. The 30A is almost brand new also bought it just before we replaced our last 30A unit.

Thanks
  • Contact PI for diagnostic assistance. Might be something wrong with the computer board. Those are field replaceable.

    That it does not show an error is puzzling.


    That is what is weird to me also as it shows no errors. The first time I hooked up my generator it had the error code for no neutral to ground bonding. I put a bonding plug in my generator and worked great.

    Also my external surge protector works just great which it would show an open ground or neutral if there was one.
