RE: Time to replace defective and potentially dangerous absorbtion fridge - davidbrady - 07-05-2013 13:16 Did I really use vent space, cavity, gas and tarnish all in the same paragraph! ROTFL RE: Time to replace defective and potentially dangerous absorbtion fridge - gondolaguy - 07-05-2013 13:36 I'm cookin with gas now.......oh, how inappropriate! ![]() [attachment=596][attachment=597] So, up north Lowes ruled king, but here in Hendersonville Home Depot is 5 times better stocked. Luckily found foam in 2X2 form so I didn't need to deal with 4X8 ![]() [attachment=598] This picture shows accurately how much room I recovered by removing the inner air box. Look at the coloration of the wood to see the Shroud of Turin imprint. RE: Time to replace defective and potentially dangerous absorbtion fridge - davidbrady - 07-05-2013 13:54 Hey Corey, On your next photo-op can you give me a closeup of this lovely bracket: [attachment=599]. The non-slide equipped LXi's are built differently than the slide-equipped bus at the roof radius. My bus has a huge quarter round extruded aluminum beam that runs the length of the bus. My roof bows terminate into the top edge of the beam. Your bus doesn't have the beam and I'd like to see how they connected the roof bows. Now I went and did it... I rounded out the controversy by including the S-word in our R-word thread having already mentioned the M-word! Yikes! LOL RE: Time to replace defective and potentially dangerous absorbtion fridge - gondolaguy - 07-05-2013 16:05 Interesting! Jennifer and I went to Camping World so we could view what's new in RVs. Every single new Class A over $200K had a residential Reefer in it. RE: Time to replace defective and potentially dangerous absorbtion fridge - davidbrady - 07-05-2013 18:01 Corey, Can you take a height measurement for me? I don't have any mechanicals under my fridge so I can set it right on the floor. I have a drawer under my Dometic and a cabinet above. I'm wondering if I remove both the drawer and the cabinet how much vertical space that gives me. I'm away from my coach so I can't take the measurement myself. Can you tell me the interior height from the floor surface to the AC duct work mounted to the ceiling? I just checked and Marathon, Liberty, and Newell use Sub-Zero refrigerators! :-) Perhaps I need to keep up with Winnebago!

What I didn't measure was the small cabinet and the depth of the A/C relief. RE: Time to replace defective and potentially dangerous absorbtion fridge - patticake - 07-05-2013 20:37 I guess I'm in a different situation, as my frig is on a 45 to the outside wall and has no vent in the wall. The air comes from a screen in the floor and has the conventional roof vent. To gain access to the rear of the frig, I have to take part of the bathroom wall out, remove about two dozen screws from a small access panel, and then I can see the back of it. If I ever want to remove it, I would also have to remove the commode so maybe I can reach far enough into the cavity, or use a sawsall to remove more wall. But, knock on wood, I haven't had any trouble with it, and it is a Norcold. I guess I can con my 9yr old grandson into climbing into the opening, if need be. RE: Time to replace defective and potentially dangerous absorbtion fridge - pgchin - 07-06-2013 11:01 Wow, Take a few weeks off to get rolling on a "walk about" and miss all the fun! ![]() ![]() ![]() -Neither refer exhibits "charring" of the cabinet and the ndr1292ss is a bit bigger and I had to rebuild the upper cabinet and make it 2 inches smaller. -the "installation" enclosure in a 95/6 EXCEEDS Dometics specifications, I was real sure when I did the 1292 install "to make it so" Obie Wan! They provided a set of specs, very detailed with the 1292. - I inspect the cabinet and coils every six months, the old rm7030's coils were "toast". The boiler stack was shot and the top of the coils over the boiler stack where it vents were all rusted through and deteriorating. - If I keep the NDR1292,I will change out the coil assembly with the Amish one in 10 years.....2017 is still way out there! ![]() - I am perplexed why some low usage units "char" (for lack of a better word) and some don't, I use mine 5-6 months a year. Inquiring minds what to know! - I am VERY RARELY level, since I NEVER use the jacks and air down, granted I do not have a slide so airing down is an option for me, for others it is not. - The new ndr1292's coils seem to be holding up well so far, but in 10 years they go period! You can't see in the boiler stack without taking it apart and according to the articles written about these refers by fire professionals and insurance companies, the "bulk" of the coil failures appears to be in there. These same articles also state the number 1 cause of RV fires is the refer. I respect Cory's and others decision, I indeed may follow, but I am going to get my "use" out of the 1292 since I had to call the ball in 07....... Great thread BTW!

A-- I don't want to paint all manufacturers with the same brush but it does appear that, while the units DO meet the standards, the standards are somewhat lower than what we expect. Camper manufacturers then exacerbate the lower standards by poor installation. I have to admit I was EXTREMELY disappointed when I pulled the original fridge in my PT and found it was not installed according to specs. I really expected better from Wanderlodge. Equipment standards happen to be one of my pet peeves. I could write a book but nobody wants to hear about it. Suffice to say while the technology in many areas has improved, the equipment standards have been lowered more and more until you really have to read the fine print to see what the performance actually is. Even residential refrigeration and air conditioning has suffered the same fate. Years ago a 3 ton unit would actually produce 36,000 BTUs of cooling at any ambient temperature usually encountered in the US. Now I frequently find units that, not only will not produce 36K, but will not even produce their sub-standard rating above 90F!! I'm gonna quit now before I start pounding on my desk and frothing at the mouth! ![]() ![]() B-- Owner maintenance of these units consists of cleaning the burner & flu, visually inspecting the condenser coil and air passages, and clean if needed. Don't forget the roof cap. Are the cooling fans (if so equipped) clean and operational? Also look for corrosion, particularly in welds and joints. The components of the refrigerant fluid in these unit is somewhat corrosive anyway and more so when they separate during long periods of disuse. To my knowledge, no definitive studies have been done, but, most techs agree it's better to run these units to keep the refrigerant mixed than to keep them shut off and have the components separate and cause corrosion. This also keeps the evaporator from rusting on the outside. I posted a link for better understanding at the end of this post. C-- I already fire-proofed (really more like fire-retarded ![]() As to the rumor, I will quote The Shadow: "Who knows what evil lurks in the hearts of men?" Sorry, I can't do the maniacal laughter that should follow.

I think heavier is better, as far a cooling units go. Quantity of refrigerant would depend on unit size but basically these units have a few ounces of ammonia, water and rust inhibitor, and then the unit is pressurized to around 350# with hydrogen. Here is some information on how these units work: http://www.gasrefrigeration.net/why%20they%20fail.htm TOM RE: Time to replace defective and potentially dangerous absorbtion fridge - Johnny M Slone - 07-07-2013 00:53 (07-05-2013 10:51)davidmbrady Wrote: I don't think there's any question that the technology is sound. I find Tom's post very enlightening regarding the build quality and standards of the Dometic and Norcold absorption refrigerators. Folks who've replaced their cooling units with Amish units have reported improvements in quality. David, not sure this will work but I am trying to attach a picture of the bracket I made to attach the front corners. I did not use the level screws on the front of the new fridge so I had a good place to bolt the bracket to and I put a screw through the bracket into the wood cabinet. I may not put a bracket in the back as I stated before, think I will run it for awhile to see if it will be needed. I had the opportunity to take a good look at the 10 year old and the 5 year old cooling units that came out of my coach. My opinion is the quality of the material used to fabricate the cooling unit is substandard. I think I have pics of both units and if I can I will post them. David I think you will be shocked when you open your fridge up and take a look at the cooling unit. My guess is it is rusted to the point you will wonder how it worked. In the mean time you have small children so make sure the smoke detectors work. John |
