Soft Start Kit for RVP Suburban AC

[Goodyear Travels]

Greetings Forum members. I have an 07 2720sl with a Suburban 9202-876 roof AC. I know it’s an old unit but it still runs fine - except when I’m at high altitude and my Yamaha EF2400is generator bogs down and the breaker trips. Does anyone know what soft start capacitor is compatible with our AC and where it can be obtained. I’m about to adjust valve lash and rejet for +7k ft altitude but getting the AC started will still be a bit of a crap shoot. Thanks, Eric

We had a 2008 3124KS that I ran into the same stalling/surge issue when running off a single 2200 Ryobi generator. I installed what is now called a SoftStartRV on the compressor wiring in unit on top following their instructions. Ran it through the stated training sequence and it worked great! Although I only used the generator a few trips, the AC unit also worked great at home when plugged into a 20 amp breaker. I did find that my generator on econo mode would stall when the ac compressor kicked in because it didn’t rev up fast enough manage the quick increase to 14 amps. When running on normal idle mode it worked perfectly. You will need to confirm that your generator will still supply sufficient wattage above 7k, I used the generator below 2k. You will need to monitor the amps or wattage because you will need to manage other loads like charging a lithium battery or running a microwave because you will be running near your generator’s running capacity with just the ac cooling.

Thanks for the part suggestion. I’ll see if I can track it down. I just adjusted the generator valves which were very loose and I’ll install my high altitude jet in the next week or two. But the generator ran much more smoothly and hopefully that’ll help with startup loads. I have a bunch of other repairs to make before heading to the mountains but it’s almost too hot to work on the trailer here in Phoenix.

With the high altitude jets and the soft start, you'll be fine. That's what I did to mine.
