Fridge propane pressure

We have only been members of the Escape family for a little over a year and joined when we purchased a 2005 17B. So far we have made a few upgrades and used it for about 4 camping trips. Our 1st camping trip this year was a 1 week stay at Rathtrevor Beach Provincial Park in June. Great week but the fridge seemed to not like the warm weather and had trouble cooling towards the end of the week. Yesterday, I borrowed a manometer and checked the pressure at the fridge. 9.56 wc It went to 8.93 when I put a couple of stove burners on... After tuning the regulator to obtain 11.95 on fridge alone and 11.00 on fridge with the stove on, the fridge dropped temperature way faster than before with a strong blue flame from the burner. It was well worth the effort.

Many of us have found that low propane pressure was a culprit with insufficient refrigerator cooling. You landed in a perfect spot. System pressure will be about 12" w.c. with no load. This maintains a minimum of 11" w.c. at the refrigerator with ~50% of trailer BTU's in use. I have provided some figures in the attached thread to help users evaluate what 50% load is. It should get someone in the ballpark. This is yet another reminder that you should check your propane pressure!

I believe that was the thread I read that made me think I should check it. The camping trip just gave me the push I needed to do the job. I have learned so much from this forum and I just wanted to share my experience. Thanks rubicon327.

Just doing a thought experiment here...I know what the recommended pressures are, but what would be the downside of running the regulator at, say, one inch wc above spec? Could such a minor increase cause appliances to run improperly somehow? Danger of blowing out seals somewhere?

On a related line of thought, I wonder what that 1” additional pressure would equate to if converted to an altitude change?

Eric: RV propane appliances are typically rated for 10-14" inches w.c.. For example the Atwood manual for the older 8012 furnace says this "The entire piping system must be maintained within a range of 10-14" W.C. with all appliances in operation." Furthermore the Dometic RM2510 service manual for our refrigerator specifically says this: "The LP gas pressure to the refrigerator should be 11 inches water column with half of all BTU’s of the RV turned on. With all other appliances turned off, the pressure to the refrigerator should not exceed 12 inches water column."

11" is just a target number to aim for so that you have some headroom before regulator lock up which in a properly operating regulator should be 1" w.c. higher than the setting. Since my propane pressure setting is 12" w.c. with no load then my lockup pressure should be 13" w.c. Still within the proper range. There has to be an acceptable range as there will always be some variation. On the other hand one user reported he had 15" w.c. and several of us told him it should be lowered.

This is a good tech article.

That is a great article. I will now go recheck my rig’s pressure, with new perspective!

Thanks again to Dave who went around at the Quartzsite gathering last year with his manometer and helped many set the fridge pressure including myself. The cooling increased significantly after his stop and is still doing great. In hindsight, I think many of the classic fridge issues would have been resolved by replacing with a better regulator and adjusting the pressure at the fridge to the correct setting.
I had the factory regulator replaced right after pickup under warranty with a much better regulator and have never had problems with my fridge. Keeping an annual check with the manometer and cleaning the orifice should keep the fridges operating well.
