Thanks for the encouragement. Today they sent back an excerpt from the manual showing the switch (that I don't have). I guess I should try calling and getting to someone who understands the problem as you said.

This Dometic Climate Control Heater battery drain issue just surfaced on my friends first boon-docking camping trip. He woke up to a dead battery and we couldn't figure out why. I told him the same thing happened to me on my first dry outing and I found I had turned on the Climate Control Heater switch not knowing what it was.

This heater is otherwise known as the "heater cable" on the factory schematics and is there to help prevent moisture build up around the doors. His new unit does not have a switch to turn it off but all the factory schematics still show a switch.

I noted on another site that you can disconnect the Climate Control Heater "heater cable" electrical supply wire inside the fridges interior light so that the interior light will still function but the "heater cable" will no longer drain the battery. They both just happen to be on the same electrical feed wire from the controller.

Not sure why they would eliminate the switch but I know from experience that door heater, as I call it, will drain a single battery overnight.

We will be performing this easy modification to his to prevent this parasitic current draw:

This is fantastic information. I've also been fighting the premature flat battery syndrome. After reading this thread, I looked at the schematic for my DM2652, and it shows a heater on the same line as the interior light. I didn't realize the unit had it since there was no exterior shut-off switch.

Just looked at the wiring at the light switch, and found the 2 red wires. Have just cut the large one, & will see how long the batteries last.

Have I mentioned that I love this forum!?

Normally, posts with links to "competing forums" are not approved; however since this information and tip (with photos) is so awesome I find I can not see the link when looking through my "blind eye."

here is the new manual.

Note Climate Control page 5.

Hate it when you get bogus info from the factory, too.
I kinda expect it from Dealers.
Thanks for the info for the Manuel.

I'm certain it affords even the most knowledgeable an opportunity to learn more, and even refresh one’s memory.
And, no, I didn’t write it or sell it. But, I’ve got it, read it many times, even practiced a few of the ideas. Furthermore, it cannot hurt your pocketbook much.
Enjoy,
Mike
Thank you.

Killer info here, I just disconnected my wire to try to avoid the drain too.
Dry camped 2 weeks ago and fridge shut down 3 days into it.
Thanks so much everyone who added to the thread!!

3 days out of an OEM battery is awesome battery management.

Just found the specs on the climate control heater for my DM2652. It's rated at 6 watts or 0.5 amp, so disconnecting it will save us 12 amp hours per day. This is a major power savings for us boon dockers!

Great book, and I am still using my Ample power charger made from their parts.

This was an awesome thread. I was parked at a hotel while doing some business and the battery kept failing every 12-15 hours. I looked this info up, found the larger red wire in the frig lamp housing. Cut it and taped the ends. The battery is holding at 2/3 charge for the last ten hours. Thanks for the tip!

Excellent! Just saved me a lot of hunting for phantom loads and dead batteries.

There might have been a switch you should turn off when on battery.
