Electrical issue

Brought my new 2018 Ventana 4369 home one week ago and plugged her in. I used my new $400 surge protector and just went and looked at it and it says “open neu detected” according to Manuel it’s on the RV side. Anyone have any suggestions?

Is your EMS (surge protector) a portable unit? If so, I'd try using it in a circuit in your house. I'm not sure how you know the open neutral is in the RV, but a test in a home circuit should show if it's accurately testing the circuits on both sides of the EMS.

What EMS brand/model?
What type of connection are you plugged into?

Surge Protector 'looks' at supply/source power, polarity, ground/neutral but doesn't 'see' anything AFTER the surge protector


Open Neutral Detected would be from the power source side---up to the surge protector

Did a search for the manual on the 34950 and this is what the online manual says...

"Load Side Open Neutral Unit has sensed an open neutral on the coach side. Call Southwire technical support at the number listed below."



Something may be wired incorrectly or there is a loose connection. I would start with tech support as noted.

If you really have an open neutral on the coach side then nothing will be working. The neutral is bonded to ground on your house side, not in the coach so there is no where for the current to flow without that neutral being connected. If things in the coach are working then you might have a faulty Surge Guard. I had mine replaced twice when it started telling me crazy things were happening.

You're likely under warranty. Call Newmar tomorrow.

On another thread there is a discussion about surge protectors. I referred to this model as the latest with more features than PI, but now we get to learn what the coach side open neutral resolution might be. Please keep us posted.

Ditto, it only looks at the SOURCE (Park) side, not the RV side. IF you unplug the RV it will still say "Open Neutral".

Suspects 3
Bad plug (on Surge Guard) odds very very low
Bad connection Plug to socket (Medium) I Have seen plugs where the pins are black with tarnish however and that usually means "Bad Connection"
and Ground not properly connected, PARK side of outlet.. HIGH probility.

It's not uncommon that the large gauge wires connected in the Auto Transfer Switch can work loose. You might check that all the wires are tightly clamped in their connectors. I don't understand how with an 'open neutral' any electricity would flow.

I stand corrected......according to Southwire this portable is a NEW PRODUCT

Some of the listed protections:
Protects against:
  • Power surges
  • Open ground
  • Open neutral (Input)
  • Exclusive Patent Pending Open neutral inside the RV

Seems it CAN check Neutral on Load Side
https://rvpower.southwire.com/surge-...a-model-34950/







Open Neutral On Coach ------as suggested check wire connections inside the Auto Transfer Switch

240 volt electric will flow with an open neutral. Neutral only carries the difference between each hot leg.
Unfourtantly, with out the neutral the voltage can varry to the 120 volt items on each leg.
My parents house lost the neutral once. Half the stuff running burnt out and the other half went dim.

Loose neutral as stated above will cause floating voltages. Not good.
