Need a little help on fridge wiring...

[asmodeus]

i am hoping someone could tell me the wiring for the fridge... as i purchased the trailer after the old fridge caught fire there was no telling what wire goes where... i am back to a point on the wiring that i have good wire and the color codes are good... just do not know which wire goes to what... thanks in advance... oh i have a '95 34' excella... thanks

There are only two wires involved. The white wire is ground and the colored wire is +12v. These go to the terminal block on the lower left of the fridge. The block will have two openings for wires with clamp screws. Just look on the fridge wiring diagram for which wire goes where.

If you need to extend burned-off wires, use #14 automotive hookup wire in appropriate colors.

I'm a long ways from knowledgeable about RV refer wiring, but isn't 115V AC also involved?

rvmobile.com has some great schematics and wiring diagrams for fridges.

The fridge has a regular 120v plug that goes into an outlet somewhere in the refrigerator compartment. I didn't mention that since I thought it was obvious.

Thanks,

I remember seeing that now that you mention it.

thanks for all the help and the link... yeah i got the 120 volt side under control... it is just when i got into things there were like 20 wires in a bundle and could not see what color was what... now the fun of tracing down the wires...

the first picture should be the bundle from the floor to behind the fridge.. the two blues are for sure to the thermostat for the front furnace... and the brown and white ground should go to the light above the dinette... not sure about the rest...

The fridge uses very little 12v. Just about any white-color pair should give you enough 12v to run the fridge. the only 12v loads are lights, control box electronics, igniter, and gas valve. All of these are light loads. Just check that you have 12v between the pair you choose or get the color from someone else with a similar year rig.

Here's the Installation manual for the Dometic fridges:
http://gasrefrigeration.net/dom_tech...300_2800OP.PDF
Has the wire connections, guages, requirements, etc.
I was looking for the same answers, so this is what I came across.
Hope that helps!

helps a great deal thank you very much...

Just got a 12v Dometic to replace old 3 way. On the fridge is a block to wire the 12v. Not a problem, but how do I ground it? I have heard people say to ground it to the chassis. How would I do that?

Is there any reason why you can't just use the positive and negative (ground) wires that ran the 12 volt element on your 3-way?

Maybe I mis-understood. Are you looking for an additional ground to the chassis besides the ground wire that goes to the power block? If so it's just a matter of running a wire from the fridge to a bolt or screw fastened to metal that is in direct contact with the frame. Does the installation manual say you must do this?
