Dometic RM24 heating element source?

[Larry Engelmann]

Hi All,

I'm searching for a heating element for my Dometic RM24 refrigerator and haven't come up with a viable source yet. It's a 110V/95W ("C" type cartridge I think). I'm curious if anyone knows where I may be able to source this part. Thanks!

Thanks very much for the link Alf!

if you get really stuck might have your electrician look into one of these.

Try Dometic America. That should have been your first stop.

Like the original poster, I too am searching for a heating element for my Dometic RM 24. Larry, the OP, told me he ultimately replaced his refrigerator. My refrigerator works well on propane and I'm not ready to give up on a heating element but it's a challenging hunt.

Dometic USA advised me the part is discontinued. They gave me the phone number for "All Seasons," a company that carries some old parts. All Seasons is looking through their boxes for me and said they'd call back.

I emailed Gammon's RV and the sales person asked me to phone the shop but my USA phone won't connect to Ontario. I'm not wild about paying to have a heating element specially manufactured, and I'm not very confident mine can be repaired. So far, eBay is a bust.

One unusual thing about this heating element is that it has 3 wires, red, brown, and black. (You can only see 2 wires in my picture because one of them slid down into the insulation). The cartridge is 4 inches. It is a 110 volt, 95 watt element. The RM 24 refrigerator is Prod. No. 9263901. I'm not sure of the part number and that makes it more difficult to search.


I'd really appreciate any help. Plus, I'd be willing to travel some distance if anyone has a used RM24 with a working heating element they'd like to sell for salvage.

what is the diameter of the cartridge?

[David Tilston]

I am only guessing, but the three wires are likely for 12VDC 120VAC and common. Using your 95W power number, the resistances should be 1.52 ohms for the 12VDC resister, and 152 ohms for the 120VAC resistor.

If you know someone who is a vaping fanatic, like my daughters boy friend, they may be winding their own vaporizer coils. I suspect that this material may be usable for new resistors.

Once again, I am just guessing, but I suspect that inside that metal tube are two coils in a heat resistant potting compound of some sort, (ceramic tile grout?). It should be possible to build your own heater, but should you?

You can get what you need here, you only need the dimensions and wattages

[stevebaz]

If you can't get a heater cartridge and are facing scrapping the unit If it was mine I would look at a cartridge for another model or buy a 2 wire 120 volt cartridge and only run on 120 volt or propane. I don't use or need 12 volt operation.

Are both windings burned out in the cartridge? if not then you could run on 12 volts through you converter.

Those dual voltage cartridges seem to be a real special deal.

Here's a manual on line if you don't have one.

Thanks Stevebaz. Two of the wires are broken just below the point where they enter the ceramic on top of the metal cartridge. It is possible they are not burned inside the cartridge. I have emailed McMaster-Carr as you suggested.

Thanks for the manual. Here is the pertinent wiring diagram for my heating element from that manual. Does this indicate the red wire is the 110v power, the brown wire is the 12v power, and the black wire is neutral?

True to their word, All Seasons RV, (574) 293-4591, searched their old inventory and found a heating element to fit my unit. It's a 2-wire element but it fits perfectly and it is 95 watts. Now I can make ice with electricity as well as propane. I appreciate everyone's advice.

Glad it worked out for you.
