Strange AC cycling?
I have submitted a service request to Airxcel for this, but I am wondering if anyone has experienced this issue? I have a 3 zone AC system. The AC on zone 1 does a strange cycling over and over. ...

If you think about your statement that the ac tries to restart and fails after shutting down within 5 seconds and then after another 10 seconds it's able to restart it reflects the imbalance in pressures in the system which is alleviated somewhat with the additional 10 second delay. Given enough time( not sure how long, maybe at least a minute delay), the compressor can overcome this load. Not sure about your system but some thermostats have a variable delay built in and can be reset.
NOT RV Tstats. The delay is built in and not adjustable. Odds are it is the Overload ON the compressor and not any other component. I also fail to see how this unit(AC) could cool down at all if the compressor is short cycling as fast as you state. Also, posting the MODEL number of the AC would help. The components on RVP AC units have changed over the past few years and they do not all have the same operational components. A few years ago I had a Tiffin with a similar complaint. You could time it almost exactly on the short cycling. Turned out a piece of Ductwork had fallen down and blocked the cold air output and this was enough to trip the freeze sensor for those short cycles. What you can do is remove the top Evap cover and run the AC. IF it does NOT short cycle you have either a defective freeze sensor or the ducting has a small blockage. Doug
