Electric/Power problem

[bethcb]

We have our new 36FBTS for about 5 weeks now and still have another week before we get home, but having some problems. Hope someone can help.
We just plugged into 50 amps at the RV park and the power convertor for the refrigerator is yellow, not green. The refer is not running off shore power. In addition, the 15amp fuse that says Refer Utility #2 is tripped and we cannot reset it. On the control panel/fuse panel there is a green light that is continually flashing. I don't know what this is, but it did not flash before.
In addition, in the last several days, the bedroom air conditioner has not worked consistently and as of yesterday the fuse trips every time we try to use it. The power invertor at time, showed a Error code 05, but that after we unplugged and replugged the RV, this would get resolved.
Not sure what is going on here, any help or ideas is appreciated!

Sounds like you might have a bad power converter that is the main power pannel that has all of your breakers , the pannel on the fridge is just the control pannel for the fridge but it works off of the main converter. mine went bad 2 weeks after we bought the trailer sitting in our driveway.

The green light on the panel is letting you know what is happening with the charger side of the converter. The light is supposed to flash depending on how the battery is charging.

Here is the info:

The Green LED on the left refers to the Charge Wizard - t

BOOST MODE – Indicated by green LED remaining on. The output voltage is 14.4VDC to rapidly recharge the battery up to 90% of full charge.

NORMAL MODE – When the battery is between 50% and 90% charged, the green LED will flash once per second. When the battery has reached
90% of full charge the green LED will flash 2 - 3 times per second. In this mode the output voltage is 13.6VDC and the converter is safely completing
the charge of the battery.

STORAGE MODE – Indicated by green LED flashing every 6 - 8 seconds. In this mode the output voltage has been lowered to 13.2VDC, the RV
battery is fully charged and the converter is maintaining the charge.

As to your other problems:

You could have a low voltage problem on one side of your 50 amp line. The inverter will automatically switch to battery if the incoming voltage drops below 90 volts. Also your a/c has low voltage protection as well. If I remember correctly that shuts down at 103 volts. The first thing I would check is whether you have adequate voltage on both legs at the post. If that is good make sure both connections inside the breaker panel are tight.

The inverter will automatically switch to battery if the incoming voltage drops below 90 volts.


The power inverter is only there to provide power for the fridge when not connected to shore power. It is my understanding that the inverter should be turned off when not in use, I.E. hooked up to shore power. The manual actually states it should be off when not in use.


The power converter has nothing to do with the fridge operation. It converts 110vac to 12vdc for all 12v powered items.

Thanks for all the info and suggestions. We are going to try to figure this out but we have to purchase a meter to check the power at the post. Sounds like that is the first thing to determine. Changing campgrounds today, maybe that will help. We are taking it in for warranty work when we get home and just hope we can use at least 1 AC until then (6 more days).

This may not be the cause of todays problem but you NEED one of these attached to the power pole before you plug in your RV.. or have one hardwired inside the rig.. expensive YES but worth every penny.

ps Amazon usually has them for less but finding it on the CW site is faster for me..

We have a surge protector.

A surge protector is not the same as a power management system. There is a big difference in protection capabilities between these two.

If you monitor your voltage with a plug in meter which will also check polarity and open grounds.Then a surge protector will most likely be all you need. The management system will shut off power when voltage varies from the norm. Typically they shut down power if voltage rises above 132 volts or goes below 104 volts. It will also monitor frequency highs and lows (not a huge problem typically) and open grounds.

You can start by turning the double pole 50 amp breaker off and back on at the power pole. We had that happen once where only one side was making contact. Make sure you give it a good shove home.
We now have the onboard surge protection and monitoring system so we can see what is going on with each circuit.
