We recently experienced a high pitched sound coming from the front of our Cougar 5th wheel. Afraid that it was something in the electrical system, we searched for the source and found it to be coming from the propane system. It would start up when there was a draw on the propane and get louder as the demand increased.
We were camping less than an hour away from our dealer, so called to see if it was serious. Tech said it is not uncommon for this to happen when there is a load on the system and not to worry, the propane system should not fail and it wasn't going to blow up, which was my concern
Since we are taking off in a few days for a 10 day trip, we stopped at the dealers on the way home. They were busy, but the tech kindly took time to help us (
for our service dept). He said it is the diaphragm in the regulator that makes the noise. He checked it out and agreed it was loud enough to be pretty annoying. It is only the regulator from the secondary (driver's side) tank, so we could easily swap the tanks if tank 1 was empty, and run off the primary position. The noise is only present when the secondary tank is turned on. This is the first time we have heard the sound as we have never run the primary tank dry.
He assured me everything would run fine. When we return from our trip they will replace the "noisy" regulator with a new one and see if that eliminates the noise. Our RV is only 4 mos old, so it will be a warranty repair
Has anyone else experienced this problem? Did you have the regulator replaced and did it resolve the problem?
