Atwood Wedgewood - Oven Replacement thermostat

[jodeb720]

My buddy has the model R-V2132W1p - and the oven thermostat has gone out. On the parts list, it's item number 16, part number 56116.

Does anybody know where we can get a replacement Oven Control Thermostat assembly?

Thanks!

Did you call Laurelhurst?

JD,

Thanks for the note. I called Atwood earlier today - and the tech support guy gave me a part number for post 2002 models that "should" fit into the unit; However, my buddy's range is a 2002 trailer model. That means the Oven is probably a 2001 model. Add to it, when I researched the part number, I can't find it anywhere on the web. The part number he provided is 52148. I'll give them a call back tomorrow to see if I wrote down the part number incorrectly.

Chris's link for the owner and service manual goes into great detail as to how to read the model number, and it's really helpful - right up to the part where the part I need isn't available.

I think it's going to require a national search from salvage yards to find an older one to replace the main unit. Sigh.

Thanks again!

Chris Bryant is an RV tech and friend of this Forum. On His Website he's loaded up lots of Owner and Service Manuals. There are two Atwood Range manuals listed toward the bottom of the page. They're labeled "2004" and "2010." The 2004 includes the "2132" Series and offers theory and troubleshooting along with a discussion of components. Download it and look it over.

Manual has pretty much the same explanation I provided above. Back in those Wish-I-Knew-Then-What-I-Know-Now days, before I learned about two oven controls and how they work together, I replaced both before the problem (oven wouldn't light) was solved. Been a dozen years, but I think I changed out the temp control (with the knob) and it didn't work till I replaced the oven valve too.

I just looked at the 2010 edition of the manual. It goes back into the earlier models too, so I think it was intended to replace the 2004 edition. Thinking of replacing old "mercury" controls with "mercury free" is supposed to call for replacing the entire appliance. It wouldn't hurt to call or email Atwood and ask if there's a retrofit kit.

Thanks so much! JD I'll be having him diagnose based on your suggestions above. I do hope that this is an easy fix...

I can't believe they don't have a direct replacement for the discontinued unit though. That makes no sense!

Check with these people.

Are you and your friend 100% sure fire certain it's this Valve? There are three parts involved in lighting the oven. I may not have it exact, but here's how I see it and I believe I'm close:

1. A little Regulator (you can see it in the left front corner of the cooktop with the cover lifted) makes a final adjustment of the LPG pressure to the Oven Thermostat.

2. The Oven Thermostat (right front, behind the Knob) allows the Pilot to be Lit. A SENSING BULB allows the LPG to flow to the Pilot and keep it lit. Does it do that? Then you set the Knob to a Baking Temperature, say 350. It causes the Pilot to Flare Up. There's a delay in Main Burner Ignition because...

3. Oven Safety Valve ALSO has a SENSING BULB. When that bulb senses heat, the Safety Valve provides LPG to the Nain Burner.

The Sensing Bulbs in Both the Valves (2. and 3.) were made with Mercury. The EcoNazis have decreed that there be no more. New ovens designed differently. New parts won't retrofit old ovens, and we may also not have valves existing ovens.

The two Valves used to be about $100 each. I don't know about the Regulator. Maybe somebody here can provide testing instructions or a detailed testing manual. If you can determine which of three parts is causing the problem and get just the one, I'd say do it. But all three, if even available, get the cost on the way to a new oven.

This may be the one, but check it out before purchase & verify. search under LP Gas category with the part # 56116. That particular part number according to a few places has been discontinued.
