That was same as what happened with mine. Worked well for first year and one-half, but then just stopped cooling on propane, even though the burner was working. We ended up switching the fridge out for the RMD8551 and so far it has worked ok.

A door closure issue, seems more common on the double door model. Need to do a reset on the electronics? I have not examined my flame that close but that looks like a pretty good blaze going on. Is it staying on? Blockage in the tube? Mud dauber nest? Location of the thermistor?

If that flame keeps going it maybe something with the coolant, an ammonia loss? Are the fins getting cold? Is the refrigerator level? Here is a link that maybe relevant,

Did I ask if the refrigerator is level?

Don't both the electric and the gas heat the same ammonia?

Yes, so if it works off electric then it still is using the ammonia for cooling.

Yes, all of the heat sources drive the same absorption cycle system. If it worked on both AC power and propane, and now only works on AC power, it seems to me that there are two possibilities (or it could be a combination of the two):
  1. the propane burner is not producing as much heat as before (even if it still lights), or
  2. the performance on any heat source has degraded, and the problem is only really noticeable on propane because that was the more marginal source all along.

The second option is certainly possible, but in most of these refrigerators the propane burner is the strongest heat source.

fridges

I wish ETI would let us take out the 3 way fridge and put in a truck fridge with 12 volt with duel batteries and solar why screw around with propane ? I've had friends come down to SW Florida and their 3 way fridges don't work so well . I talked to Sarah she said they could delete fridge and leave the cabinet open .I would have to get my own . I still don't know what $ one would get deleting the 3 way fridge .

If we get the 3 way can we just run on 12 volt or 110 ac and forget propane .(I did order the extra rear fridge fan)The only time propane comes in handy is boon docking for hot water and burners for coffee.The SE of America most campsites have elec 110 even in national parks . That's why I wanted solar to keep up the fridge on 12 volt . I hope this new Fridge for the 21 is up to the SW Florida Summers

Clean the propane jet? Crap from the propane filling tank flies in and restricts flow.

Add a couple of these to the system, one on each side of the regulator. Got mine on Amazon.

This looks like the AFC Model 155, a 40-micron inline filter. That makes some sense to me to catch particles, although I don't know that it would make any difference to the water and oil that also comes with propane.

How often do you find you need to clean these filters? Does it come apart without rotating the pipe threads? It seems like would be a pain to clean if everything on one side of the filter had to rotate to unscrew the filter holder, and of course it's crazy to undo a tapered pipe thread just to clean a filter.

Also, the differential pressure to flow chart suggests that nothing will flow through it in low-pressure plumbing, so it would only be useful upstream of the regulator. AFC suggests it only for the inlet of the regulator.

I don't see the problem. Order your trailer with the fridge deleted.
