Expansion Valve

[pappaono]

Does anyone happen to know the model number of the expansion valve that I believe Evans used on a 2004 Sea Breeze and a ball park price that a new valve will cost.

Thank you

We just ordered one for a 2003 Tradewinds and it seems the same one is used in most motorhomes. The number is RV218310 Evans Tempcon Expansion Valve. We got it from Johnny's Radiator Shop in Warren AR. You can go right to the Evans Temp site and get numbers for all kinds of things including that expansion valve, compressors, etc. Here is a link to that.

Thank you Deon I found Johnny's Radiator Shop in Warren AR. web site this afternoon and ordered that same part also. Now all I need to do is get it installed and hope it cures all problems. Look like it might be fun to get to.

Believe it or not, we had to take the entire lower front end off (the part with the headlights). It was the only way to actually be able to reach that expansion valve. We had a catastrophic failure of the dash AC when we got home this spring. We have purchased a new compressor, dryer, and expansion valve (so far!) Jim will install all the parts but we will have to pay someone to flush the system and recharge it with freon. That sounds as though it will be the most expensive part of the whole project. We also need a new belt as that got so hot it melted. At this point we aren't really sure what exactly happened. It either ran out of freon and/or oil, or both and possibly the switch that is supposed to shut down the compressor if that happens also failed so I presume that will get replaced too along with the Schrader valve. Good luck on your project. National did not make it easy to access anything once the coach was finished. By the way, be sure to use flare wrenches when losening the flare nuts off the expansion valve so you don't strip them. That would be a disaster!

Must be a common problem. I also ordered the same valve and dryer from Johnny's this afternoon. Very easy people to deal with and it should ship today. The shop that was re-charging identified the bad valve after they filled the a/c system with R134a. At least they were able to reclaim the refrigerant so I only paid for the labor. Will go back as soon as the replacement parts come in. Hope that's all that will be needed. Appreciate the on using the flair wrench - that's one reason I like this forum.
I should also add I spoke with Evans (Carol) who was very helpful. Had talked to her earlier this week on a failed connector on the high pressure line from the compressor to the evaporator (I think) all 39 feet of was was replaced. Carol confirmed the fitting size so I was able to have the replacement hose made locally.

Should have bought a 30lb cylinder of 134A from Sam's about 3 years ago for $78. I just tapped mine after sitting for all that time.

Will you guys let me know what the suction pressure is after you get it going. Can't get mine above 23 lbs I'm thinking my valves getting bad. Got good superheat, just freezing the coil.

No, National did not make it easy to work on, my mechanic believes he can get to the valve by removing the head light assembly and going thru the opening. Hope that does the trick, I'll tell him how you are going about it. Good luck to all having the same problem.

not sure where your expansion valve is located, but that was the same problem I was having on mine. After removing the radiator overflow tank the mechanic was able to get to the valve and replace it. He also had to use his digital camera to take a picture of the Evans box to be able to read the label on it that showed the amount of freon needed. Now have good cold AC which will keep DW cool.
