2020 Riverstone Partial Electrical Loss

Recently moved home after a job. Hooked up to shore power as usual and noticed a few appliances donít have power and my residential Samsung Inverter Fridge has power, but wonít cool. Iíve reset the fridge, but donít hear the compressor kicking onÖ..noticed my fridge doesnít have a dedicated fuse in the panel.

Besides the most likely compressor problem, my dishwasher, both fireplaces, and washer wonít power on at all. Iíve checked all the breakers a d put a volt meter on them to make sure power is flowing.

Forrest River tech said to check the GFCI in the storage, but I donít see one. Iíve checked the inverter as well.

What are you plugged into for shore power. Are you using any kind of adapters on your shore power cord. It sounds like maybe you have a 50 amp rv and half of it is not being powered.

It’s a 50amp plug on a 50amp breaker that i’ve used before.

I would start there. You may have lost a leg of power

If you open up the electric panel in your rv, you may notice breakers on each side of the 50 amp main. See if all the items not working are all on one side of the main breaker. If so, then you may have an incoming leg not working properly. Refer to the diagram in post #2.

I’ve checked both legs with a meter and they have power.

120 volts from each of the hots to the neutral at the panel? On each breaker?

The inverter

The inverter connection is kind of tricky. It has an automatic transfer switch. If shore power/generator is available, it cuts itself off the circuit and cuts shore/generator power through. If there is no shore/generator power, it connects to the circuit (refrigerator, some outlets and some appliances).

You won't see a breaker for its 120Vac power on the panel diagram that WMTire posted. Its breaker is on the inverter itself. If that breaker is tripped, the refrigerator and possibly some outlets and appliances won't run, even though the inverter itself is not producing power.

One question: You said the Samsung refrigerator has power. That suggests that the transfer switch IS working, and the theory above is incomplete. But it wouldn't hurt to check voltage at the inverter and transfer switch.

I’ve checked to see if the inverter breaker button was tripped and it’s not. The green LED light is also flashing the “ok” signal. But I will throw a meter on it just to check.

Check for 220v across the main breaker, not just from hot to ground. You may be picking up a load on a circuit
