Sunrader spare igniter for Suburban Furnace? 1982 NT12LE

Thu, 23 Apr 2026 15:03:33 +0000

So, I am looking for an igniter for my furnace - original type with 2 wires. My 1982 model is an NT12LE, and I bought a 525019 igniter off the Suburban website. It's got the same two wires, the same bolt pattern on the mounting plate, and the same 3 prongs on the furnace side (2 igniter prongs, 1 temp probe prong).

Has anyone else been able to find a source for these? Mine works, but we plan remote trips and I want to carry a spare. Thanks in advance.

1991 Dolphin Water Leak

Wed, 25 Mar 2026 17:50:57 +0000

There is a leak somewhere above the black water tank and the restroom floor by the toilet not the shower but only when I turn on the water pump. It seems to me that it might be the water line from the pump to below the toilet floor. The floor inside the toilet floor gets all wet and water drips from behind the black water tank. I would think that I would need to remove the black water tank to get to the leak. If I'm right how can I do this with the least amount of damage? The restroom is at the rear of the vehicle.

Suburban vdsi 6-3 anode

Tue, 18 Jun 2019 16:18:44 +0000

This water heater is an odd little beast, I am finding it difficult to get specific information. I would like to check the Anode but where I would expect it is just a drain plug. I thought it might be where the drain plug screws in but I can't tell how to remove it.

wet carpet behind driver seat

I just noticed the carpet is wet behind my driver seat. What could cause this? A leaking freshwater tank? I live full time in a 91 Sunrader.

All manuals for a 86 Toyota Dolphin

Fri, 25 May 2018 15:27:18 +0000

I bought my Dolphin about 2 weeks ago. and I came with all and I really thing ALL the owners manual from the Generator to the Toyota Truck owners manual. it even had the Original manual from Dolphin. I have Manual for all appliances as well.

I thought I would ask to see if anyone else could use this info. I'm not sure how I would get copies and post them here for others but I thought I would offer I know how hard this stuff can be to fined. (with other projects I've done)

let me know if any of it would be of use to you.

My title says 86, but the badge on the outside of the coach says 10/85

Older Dometic Refrigerator RM461 Runs Too Cold On Gas

Wed, 09 Apr 2014 02:43:04 +0000

I'm a newbie with a 1985 Toyota Dolphin. The frig works, but no matter what thermostat setting (1, 4 or Max) it gets down to about 12 degree F overnight. After reading, I tried disconnecting the thermistor from the fins in the rear, but get the same result. Does anyone have experience with these older Dometic refrigerators (non-electronic)? Does this sound like a bum thermostat? Anything else I should try before purchasing a thermostat? If it is thermostat, should I have a regular repair place do the work or is a reasonable DIY project?

Thanks.

Tricks to remove shower?

Sun, 28 Sep 2025 19:00:51 +0000

I’ve removed the toilet, and removed the screws holding the flange down. Are there any tricks for removing the toilet flange and the shower drain? They don’t seem to unscrew or pull up. Do I need to drop the tank? Thanks for any help!

My Dometic Fridge Died! 😭

Fri, 23 May 2025 02:31:04 +0000

I have a 1991 Itasca and my Dometic MR-2410 (4 cubic feet) has died a proper death and I need to replace her. I'm struggling to find a replacement fridge that fits into the space of the old fridge, and I'm really not looking forward to remodeling the cabinet that holds it. Has anyone had any success in finding replacement fridges?

I'm open to a compressor fridge instead of an absorptive fridge if it fits.

Domestic fridge gasket

Sat, 04 Jul 2020 00:02:46 +0000

Has anyone replaced the door gasket on the Dometic fridge? Is this a difficult project? The gasket on the bottom of my door is damaged and requires replacement. Can you replace only the damaged gasket or does it make sense to replace the entire door gasket?

Fixing my dripping sink faucet-waterline question

Thu, 03 Apr 2025 15:16:46 +0000

Good Morning Campers! I have a little drip drip drip and my water pump cycles on constantly. It is just the faucet (cheap o plastic thing). So, I will turn off the water and either just get a replacement gasket or maybe even replace the faucet since I have been wanting a taller neck. My question is: Do I turn off the water under the couch? There is a shut off valve between the freshwater tank and the water pump. Or do I need to shut off downline of the pump? Also, that valve seems VERY stiff. Do we think it is just overtightened? Should I force it? Thank you all! Just a solo camping girl here trying to figure it out on my own. You all have always been so helpful. I appreciate you!

Igniter for 2-way Dometic RM2410 discontinued - replace fridge?

Tue, 22 Oct 2024 20:15:52 +0000

As title indicates the original igniter for the fridge in my 93 Warrior cracked and no longer works on propane. It works on electric.

I've taken it in to a reputable RV shop and they contacted Dometic and the igniter is no longer made. They tried an igniter that is supposed to work but no joy.

Contacted another shop and they also could not find an oem igniter.

Both shops said new replacement fridges were in $1k plus not including labor to install.

I'm now contemplating taking it out and using a 12v portable chest compressor fridge or compact home fridge using a separate lifepo4 battery, charge controller and inverter to power (I'm not sure how to change the whole original 12v inverter/converter to lithium). If I do the portable chest I could also use in my suv which would be a plus.

Has anyone replaced with either of these options? This guy converted a chest freezer to fridge which I thought was a cool idea

Where can I find replacement faucets for the bathroom and kitchen sinks? Is this an easy job to do myself?

How to troubleshoot Dometic RM2400 cooling issues

Thu, 20 Mar 2025 18:49:44 +0000

Hi,

I have a Dometic RM2400 refrigerator that cools but not enough. I had an RV guy replace the cooling unit but it still doesn't cool enough (even when on max). The dial doesn't actually stop on max and I can just freely spin it so I don't know exactly when I hit max and when it "resets" to zero. It have been running it on AC and haven't tried gas yet.

What else can I try?

new AC too loud

Sun, 02 Jun 2024 16:08:01 +0000

I had a new Coleman Mach AC recently installed into my 1987 Toyota Dolphin.

It is super loud. Is this inevitable due to the small coach size? It seems like most of the noise is from air rushing out of the vents. Can I adjust the blower speed to just deliver less air?

furnace motor dying and out of stock???)

Thu, 16 Jan 2025 21:32:54 +0000

hello all -

my 1992 itasca’s furnace (suburban model #dd-17dsi) has a motor which seems to be dying (suburban part #231916). i cleaned what i could

reach but still not spinning fast enough to push the “sail” into the right position. (when i manually

move the sail, all works fine - so it’s not the switch). it could be the bearings, brushes or ?). i have been unable to locate exact matches through rvupgrades.com and adventurerv.net: “out of stock”.

any ideas on other places to try? or knowledge of substitute brands or part numbers which could will work?

thank you for any insights you may have!

safe travels -

Going the Mini Fridge Route

Fri, 07 Feb 2025 16:54:49 +0000

I've been thinking hard lately about pulling the original Norcold 875EG2 out of my rig, replacing with a good mini fridge. The Norcold generally works but is WAY old, hard on the eyes, and BAD at maintaining a consistent temperature across day/night. Also, I already have an (efficient) inverter setup to supply the 110v for a standard mini fridge, and we just never use the existing unit on propane (moot point, for us).

Couple thoughts and questions:

Anybody done this recently and have thoughts/suggestions/regrets?
The Norcold has about 4.5 cu.ft. capacity, is "built in" and fits snugly into the surrounding cabinetry, and is roughly 40" H x 23" W x 20" D.
I haven't found anything that matches those ^ dimensions closely, especially in height since most are between 30-33" tall. So I either need to "wall-in" the additional space, or create some kind of cubbyhole storage area, below or above. Any opinions on this?
Biggest Concern: should the original fridge outdoor access panel and roof vent be sealed and insulated... or left as-is?

Suburban furnace quit working (again)

Sun, 03 Nov 2024 16:54:41 +0000

Hi Everyone.

I have a suburban NT-16 furnace in my 1988 Toyota Odyssey. Back in 2019 I was having issues where the fan would start, but the ignition sequence never happens. To resolve it back then I bought a replacement board from ebay like this one: https://www.ebay.com/itm/386313082243?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=n-ju0w2ptyy&sssrc=2047675&ssuid=1-1GOiu-Twm&widget_ver=artemis&media=COPY. It solved the issue for me at the time, but the issue has returned.

I've done some troubleshooting steps including:

-Test the propane supply by replacing the regulator

-Bypass the propane plumbing by connecting the tank/regulator directly to the inlet on the heater

-Test sail switch with continuity tester (good)

-Test resistance over both propane valves (40-45 ohm, good)

-Check for voltage to the control board (good)

-Check for voltage at the propane valves 30+ seconds after fan start (no voltage)

I think this isolates the problem to the board.

Does anyone have experience with these? Are the newer boards unreliable? Should I buy another one or potentially a Dinosaur control board (https://www.dinosaurelectronics.com/UIB_S.htm)? Should I bail on the whole thing and replace the whole furnace (either with another NT-16 or maybe something else???)?

Thanks for being a great group.

91 Winnebago - Drain Valve Replacement

Mon, 13 Jan 2025 02:12:24 +0000

I know this has probably been covered a few times and could be solved a couple different ways… but the drain valve on my fresh water tank recently broke internally (the pull-ring portion broke away, leaving no way to open/close). Obviously I’ve got the original polybutylene lines everywhere, and there’s not a ton of extra room to work with between the tank and the hole cutout in the floor, where the valve drains out. What’s the best/easiest way to fix? Replace this section with Pex? Cobble together something else entirely?

Appreciate the tips and ideas!

Dometic Freedom Fridge Door handle

Can anyone point me to the part for replacement of my Dometic freedom fridge door handle? It's just not staying closed and the pin keeps popping out the top.
