GFI Circuit Plug

There are several reasons why a dealer wouldn't want to use one from Home Depot...

1. It's cheaper and you wouldn't feel you're getting your money's worth.
2. It's readily available and you wouldn't have to wait a week or more for your rig.
3. Since it's such an easy fix you would want to do it yourself.

By puffing up the repair it makes it easier to charge you the big bucks without you making a fuss.

Tell the dealer, you'll live with it, pay him for his diagnostic time, (one hour tops) and replace it yourself. Easy fix, 15 minutes maybe. Just make sure the power is off at the receptacle before proceeding. Notice I called it a RECEPTACLE...a PLUG is what you "plug into" a receptacle....Dennis

Some are different in that they are a sealed self contained unit for RVs. If you pull the plug out of the wall and it is in an electrical box you are good to go for a Household replacement. If it isn't in an electrical box I would be very cautious about installing one that is not sealed w/o a box.

Ditto. I replaced mine with one from Lowes and it works fine.

They are just common household GFCI's - nothing special about them and certainly not RV specific.
Your dealer should have gotten one at home depot for $12.

None that I am aware of.
