One more question. Are you hooking up to a true 50 amp split phase 120/240 volt service at your house.........or are you using an adapter to plug your 50 amp (4 prongs) RV into a 30? amp (3 prong) plug.

If using an adapter, you will need to check all the voltages between the plugs as per the chart for the adapter (which is the last plug shown)

If this is the case, you are frying the electronics as stated. You need to immediately check your house 50 amp plug for the voltages according to the NEMA 14-50 service between all the plugs in the chart below.

I almost did that on my first go round with 30 amp service, I went to the RV dealer and asked for a 220 volt adapter to my 30 amp plug, the young lady at the sales counter straightened me out in a quick minute. This (couldn't have been more than 20 years old) young lady fully explained the how TT circuits worked so went to Home Depot and got the parts and installed a 30 amp wall plug in my garage. She saved me from a lot of misery and expense.

We've had several members do that, and use an adapter to plug into a 240 volt 30 amp outlet. This causes 240 volts to go up both lines of the RV and fries the usual three things......converter, television, and microwave.

A lot of fellow RV'ers don't know (and I didn't either originally), that even though you are hooking up to a split phase 120/240 volt service, that the RV utilizes each line only as 120 volts and doesn't combine them which then has 240 volts.........so you are never ever using 240 volts. The RV only use 120 volts. They (and even electricians) see the big plugs and automatically incorrectly assume it needs 240 volts.

It just seems strange that this didn't happen immediately though to the OP, and it gave up the ghost later, but we did have another member who the same thing happened. She used it for part of an evening with A/C before the converter fried. She had an electrician incorrectly wire her outlet 240 volt on a 30 amp.

That's why I'm also curious to see of there is something else messed up.

wiring is correct.

All the wiring is correct. 2 120v legs, one ground, and one neutral, of course the neutral is on a grounding leg in the main box. Still lots of fun in the camper, it had to be a friday rig. my wife had just walked under the ceiling fan and sat down when the dam thing came flying apart. Close call. The fan blades are attached to one peice that bolts into the motor. One screw holds the peice connected and apparently someone didnt consider using a lock washer or anything except the screw to hold it in. We love our camper. but you gotta watch your butt, seems i will be carrying alot of tools with this thing until all the bugs are worked out. i called the dealership and asked them if this was normal to be having all of these issues. (decals are coming off also) their answer was that "of course they do until all the bugs are worked out and surprised we didnt have more" Now thats a bunch of crap! Its called Quality control wherever i have worked and it seems that Forest river may be having issues on that front right now. Thank God my wife is an attorney, one more problem and she will file for a lemon law suit.
