1. I would indeed suspect the Dometic Stove reg's are bad. But, I doubt Dometic will fess up. It took months last year to get Dometic to agree that the Atwood Water heater Control boards on thousands of DSI water heaters were faulty. They then replaced them. Probably the same thing now. Their supplier has built faulty regulators and it will take time for the bad ones to show up in service centers before Dometic realizes the problem. You need to contac Dometic and explain in detail your testing process so they will understand that they are dealing with someone that knows RV LP systems. Hopefully they will want all your regulators back for testing. BTW, it is RARE got the Range/stove regulator to go bad. Usually they just leak. Doug
I wanted to give an update. I'm not getting very far and I'm close to a dead end with Dometic.
I started this with buying 3, new 51062 stove regulators. Two from one place, one from a second place. All 3 of them would not regulate, they would just pass whatever the tank regulator was sending. Even when the tank regulator was sending 14" WC, downstream of the stove regulator was at 14"WC, even with a burner running. I explained my testing method in the first post of this thread.
So I bought 3 more new ones from a third supplier. I tested the first one and the same thing, it would not regulate down the pressure. I have 2 more still in the package. Then I started to look at the mfg dates and the serial numbers. They are all very close together. They must all be drop shipped from the same Dometic warehouse as 3 vendors selling them canโt have stock that close together.
I called Dometic 3 times trying to get some form of resolution. The first call, the tech would talk to me. I explained exactly how I did the test. He listened and had to talk to a master tech. When he came back, he stated the regulator will no longer drop the pressure. I stated years back I had some that did drop the pressure, just these new ones will not. He stated the old ones did, but the new ones will not. I tried to ask then what does the regulator do? He stated it helps make the stove burn more even.
I asked, OK how does it do this if it does not regulate? There are only 4 parts in the regulator, a spring, a spring pressure adjusting screw, a diaphragm and the poppet valve. I can see them. He said he didn't know but the new ones do not drop the pressure. He said he would send me some information on them. Nothing has showed up in 2 weeks.
I called again today, this time I get a new tech. They will not talk to me as I have no dealer number. I explained my situation of repairing campers but Iโm not a Dometic dealer. I stated, all I want to do is report a potential warranty issue, how I tested it and the results. I do not need technical help. I can even send them back and you test them. He said they ship 6,000 of these a week and no one has complained they do not work. He would not even talk more about it. I asked who in the company can I report this potential warranty issue to, he said there is no one. They do not have the engineering staffing to do this. I could tell I was getting nowhere, ended it with have a good day and that was the end.
I called back again a 3rd time to the customer service and got the same nice person who forwarded me to the tech. She went over and talked to him. She said for liability reasons they cannot talk about technical things like this without a dealer number. I explained, all I want to do is report the issue, I can even send them back to you and you test them. She did not know how to respond to that. She was kind enough to give me an email address I could write in explaining what I found and she would send it to a supervisor.
So that is where I'm at. I did look up the Seven Universe website (Seven Universe is who makes these now) and the GR60 LP regulator has an outlet pressure setting of 8" WC ~ 10" WC. It can pass 60,000 BTU's per hour. It is a pressure regulator.
I have the 2015 Atwood range service manual where it states all the new Atwood ranges use the Seven Universe brand regulators and they are to regulate to 10"WC down from up to a 13" WC pressure at the main tank regulator. I was going to explain this too, but I was never able to get this far.
I am not sure when Atwood Mobile sold out to Dometic, if Dometic actually changed the way the regulators work. The 2015 manual I have is now 4 years old and I do not know if there us a new one. It makes no sense to me they would be selling the same part number, 51062, to interchange into all the old Atwood ranges if they somehow changed the way the regulator is supposed to work.
Has anyone else recently tested some of these current mfg Seven Universe regulators? The mfg dates on the 6 I have, 2 are from 11/15/18 and 4 are from 1/16/19.
Right now I do not know how to buy one that will work. Unless I change brands and use the one Suburban ranges use. Do not really want to do that.
Thanks for listening. Anything you can add is much appreciated.
