Yes, I did a search and there were no related previous posts. I read another posters thread about wondering if the light goes out or not and enjoyed some of the more humorous replies and tried to look past the snarky old usual posts from the usual snarky folks.Anyhoo - the light does not go out when we close the fridge door. I took earlier advice and used my phone to video the thing after the door is closed. Yup, STILL ON!! WTF???? The plunger thingy (tech term) seems to work in that it slides in and back, it just doesn't break the connection to power. I can't for the life of me figure out how to get this thing free from the top of the fridge as I can't see how it is held on up there. It almost seems as if it is glued up there. There is no way to pop the thing into two halves so I am flummoxed.Anybody in the collective here have any experience gutting and repairing these things? ThanksCheers!Mike

Look up everything you can find on your model of frig. Make sure there is not a delay function involved in it before you tear it all apart. In todays world you never know.

The fridge light was burnt out when we got this thing. Got a new lamp, one of those glass fuse looking things, and it draws about 1.6 amps. Found that with the fridge door closed it still did. Oops! > TrimetricSaves the Day Again

Some RV fridges have a switch of some sort that turns the light on all the time, using it as a little heater (for climate control or cold weather operation or some such, I can't recall precisely what at the moment). Maybe that's what's going on.

Yes, gas absorption fridges usually have a climate control heating element wrapped around the perimeter of the freezer door to help minimize frost build up. It's a 12 vdc heating element so when dry camping it's drawing down the battery, however manufacturers in recent years started deleting the switch used to turn this element on/off. This is irrelevant if you're camping on an electric site but if you're dry camping it's unnecessarily depleting the battery. The solution is to add your own switch, just as I've done ... however, this has nothing to do with the fact the fridge light is not being turned off when the fridge door is closed. In the OP's case it sounds like the switch is faulty, if so just replace it.

No, Darnit, The Light Doesn't Go Out When I Close The Door!

Solving this problem, depending on the make and model of your fridge, may be so easy you will FACE PALM when you do it.

On your fridge there is at least one switch, and possibly two, these are likely slide switches, On/OFF not knobs and not push buttons.

one is marked something like Moisture control
This switch controlls a genuine heater that is in the area of the door seal, the job is to heat it enough that water does not condense when you open the door.

The other is marked LAT or Low Ambient Temperature This one keeps the light on when the door is closed. That is it's function to keep the light on

I do know why, but clearly the fix is to turn it off.

Why keep the light on

Turns out if it's cold enough out (neer seen it that cold) the firdge does not run enough to keep teh frozen froze or some such so adding a bit of heat (from the light bulb) inside the refrigerator keeps things working properly

And yet, it still exists. And makes perfect sense.

Maybe you should redesign your add on switch.

It’s a switch I’ve forgotten about several times myself, and have to reacquaint myself with once in a while. It works exactly as described, when it’s “on”, the little light stays on when the door is closed.

It’s the same method I use for my beer fridge in the garage during the winter. The freezer section doesn’t stay cold enough when the ambient temps are below 40-ish, so I put a jumper across the door switch to make the light stay on all the time. The 25w bulb adds just enough heat so that it runs a little more and the freezer stays at the proper temp. Amazing.

:):)

Great info but sorry, absolutely no switch anywhere on my particular DM2652 ... I've been over it with a fine tooth comb and I can guarantee there is no switch anywhere. :( However, according to Chris's explanation perhaps the light in the OP's fridge is intended to not go off. :h

Hopefully there is a switch that will solve your problem.^^^^^ If tearing into the door switch is hard, then I would replace the bulb with a LED that will draw 0.1 amps and not worry about it.

If you post the make and model of the fridge you will get better advice.

Try to access a parts book.

Sometimes the key to figuring out a puzzling design is to look at the entire part. Your local RV service center should be a starting point. Once access is made use a 12 volt test light and if power is showing on both sides of the switch disconnect one wire or a harness and check either for continuity or power on both sides of a disconnected switch.
