AC quit then restarted 15 min later. Problem?

I accidentally set my AC thermostat too low and the unit started. I immediately set the temp higher to turn it off and did this because I didn't notice what temp turned it on. Then I slowly lowered the temp to see what temp turns it on and it wouldn't come on.

After a few minutes I set to temp to a value that I knew would bring the AC on. Nothing. I left it. About 15 minutes later it came on.

That the AC didn't come on immediately when set much lower than room temp, is this a sign of a problem?

    We've experienced a longer delay in compressor start when the campground voltage was low. I can only figure the compressor gets hotter, stays hot longer, and might also be harder to start.

    True to a degree. There is NOTHING that monitors the compressor pressure. The RV wall tstats/control boards have about a 2 minute 45 second delay each time the tstat is reset. The compressor will usually bleed down in that time frame to prevent an overload when starting. Doug

    that is why my multi-function surge protector has a restart delay.

    Hi,

    Normally the off time should be only 3-5 minutes. However each time you tried to turn it on, then shut it off (by raising and lowering the temp) you could have re-set the off timer.

    So yes it is working normal, but should have only stayed off for 5 minutes.

    No, but it should be 5 minutes, not 15.

    Once you turn it off while running. It takes a few minutes to reset itself. Sounds like all is well. It's normal. Scary though huh.
