Just got home from our trip and ran the generator for 24 hours without a hiccup. But the temps were below 85. The only time I had issue was when temps were above 95 and as high as 107 in WY! My buddy who has 364 also was having transfer switch problems, but his would kick back in after a couple minutes and the generator stayed running. I'm still believing that my issue is vapor lock.

I just drove 2 hours in 95+ heat. Stopped and listened outside RV when AC units quit. Generator still running. But, transfer switch makes a grinding noise every 10-15 seconds or so. And, when it does this the generator acts like a load is being turned on.

I checked oil level and it was fine. So, something is causing transfer switch to activate back and forth. And, that switch was very hot to the touch.

I am now camping on shore power without issue.

Low voltage will make sounds like that in the transfer switch. Noticed this on a low voltage shore power situation. Could also be heat related.

When the transfer switch drops out, for whatever reason, vapor lock, low voltage, etc. whatever loads are on- most likely the A/C's, the transfer switch can't RE-engage due to the load, so it thumps loudly as it tries to reengage and can't, so it kicks in/out rapidly. Turn the A/C units off, the transfer switch will reengage and allow the A/C unit(s) to be restarted. This issue seems to be worse when the temps are high. I've tried jumping across the transfer switch with wires to eliminate the transfer switch, the load will kill the generator, SO that didn't work. Everything I've tried- nothing in 3 years has resolved this issue.

Sounds as though your generator is too small for the load you are putting on it. Have your AC units checked for amp draw and possibly put on hard start capacitors and fan delays. This will help lower the amp draw.

So, a brand spanking new RV comes with either a generator or a transfer switch that will not carry the load in hot weather, which is when you need the AC units the most? Sounds off.

Has anyone ever talked with FR about this issue?

Hot weather creates lower-density air, which changes the air-fuel ratio of the gasoline-to-air mixture supplied to the genny's engine. This reduces the power that the engine can produce, and shows up mostly when the engine is working hard to produce its maximum power. The same thing happens as altitude goes higher. Electronic fuel injection can reduce this effect by sensing intake air temperature as well a altitude. If you have a carburator, no automatic adjustment is possible.

Bottom line is that you should try to limit the electrical load on your genny in hot weather and/or at altitudes above 5000 feet.

I have a six year old coach, 5.5 kW gen, it will not handle both airs at same time. I recommend you drive with one air and see what happens. Biggest voltage draws in motor home are air and microwave/convection. Just a thought.

That's a great point regarding Density Altitude...isn't there an adjustment on the genny that can be made for use in higher elevations? For example, Phoenix already has a DA of 3500' at 6AM and should rise another 1000' with daytime heating.
