Oasis Zone Fault

[Jim]

On your other heat sources, you have heat pumps, not just air conditioners, so you need to find that selection on your thermostat. Mine is simple, but yours may not be.

Thanks Rich! It's simple now that I understand the terminology and where the settings are. But last night, well not so much!

 

[Jim]

If you change the fuse and it immediately pops the new one, you have a bad (stuck) pump.

Hey Rich, were exactly are these fuses?

 

[Neal]

Well, I'm not Rich but I can answer the question if you want.

Pull off the cover plate in the panel next to the OASIS system, wall mounted. Nothing holds the cover plate on. This should be addressed in the troubleshooting manual. I think some fuse positions are inaccurate in the manual. When I had the issue I pulled and inspected each blade fuse.

Here:

 

[Jim]

Thank you both. The burned fuse appears to be the top one. Can one of you bring me a 10amp fuse, please?

Thanks in advance . . .

 

[Rich W.]

Well chances are it will pop a new fuse anyway if you have a bad pump.

 

[Jim]

I'm expecting it will, but I need to have some spare fuses in the toolbox anyway. So I'm off to the nearest auto parts store. Again, thank you both.

It did.

 

[Rich W.]

This is how I carry fuses and other small repair stuff. It’s a little disorganized right now but I constantly update it by adding and deleting stuff as appropriate:

 

[Rich W.]

It did.

Thats good - you have your diagnosis!

 

[Jim]

Thats good - you have your diagnosis!

Yeah, even if the fuse worked, I would always have wondered for how long, right? So yeah, onward and upward.

 

[NWIP]

Actually it onward and inwards towards the back of baggage compartment

 

[Jim]

Carry a spare pump at all times, they can't be trusted! They went to a newer version which supposedly is better. I got mine from ITR but others found replacements which sound good but I have yet to need.

I bought 3. Figured I need one, and of course I'll want a back up. But went a step further and felt that when I use my backup, I'll need to replace it. So decided to go ahead and get the replacement now instead of waiting until I need it.

I climbed into the bay and peaked over the partition. It appears the pump(s) are inside the Oasis, covered by a metal panel. On the panel it indicates which loop is which. Doesn't really seem like it's going to be that bad of a job, but then again, I haven't actually pulled the plate off and looked inside.

 

[Neal]

I don't think that's correct. The pumps are in a separate housing from the "green" unit. You should be able to follow the cables out of the OASIS FUSE PANEL to the back which will lead to the pumps as you will be needing to disconnect this cable at the connection location in the cable path.

I don't see any other place for them to be, @Neal. The hoses that carry the fluid in/out of the pump seem to converge there as well. One side says Loop 1 and the other says Loop 2.

Crawl in the passenger side and look directly behind your shore power cord reel compartment. Do you see an enclosed box with wires that lead off to the OASIS compartment?

I'm not at my coach, maybe someone such as @Rich W. can provide a pic. Also refer to the troubleshooting manual as it should point it out.

Yeah, that's were I was Neal. I'll crawl my fat self back under and get a picture. lol, hold on.

 

[Neal]

Unscrew the wall if that helps, not a big deal to remove it. Will have to do so to replace the pumps. Maybe in your London Aire it is located in a different location as you have bigger basements. Don't know...just going on my layout.

 

[Neal]

There is a cable coming out the back of the OASIS fuse panel (wall mounted next to OASIS as you know). There is a cable that connects the fuse panel to the pump (distribution) unit. Follow the cable(s).

I'm going to wait until I get home to take the panel off, right now I'm freezing my tailfeathers off over here at the campground.

But yes, I'm looking at the right place, but I incorrectly said they're inside the Oasis. There is a separate enclosure that says "Oasis", but it is separate from the unit that does the heating. The pics are poor, but it's really tough to get a picture in the dark, cramped up under there.
