    Cycles on and off every 10 secs after washing

    Hello all--Just a quick question I live in AZ and today i took the garden hose and cleaned the coils on my outside unit it was soaked for sure.. Coils and all came out clean.. My question is after i was done i powered unit back up but it started to cycle on and off every 10 to 15 seconds strange--Only after i washed the unit with hose did this happen..

    I waited about 1/2 hr everything dried up and bingo we are back in service..

    My question is--What did the hose water do to the unit that rain doesnt do--We do get some hard down pours here around monsoon season and the unit runs flawless.. I did start cleaning the unit right after it had just turned off from a cooling cycle..

    Any ideas! Working 100% now as it always did.. Thanks for any help Have an awesome weekend. Mark BTW unit is a Bryant about 7 years old.......

    maybe you got water in an electrical connection. maybe the refrigerant acted differently in a water logged coil and a high or low pressure safety was activated. Rain doesnt completely clog the coil fins.

    Sounds like it was cycling on it's low pressure switch until you left the condenser dry.

    Your indoor air flow may be on the lower end of allowable.

    Possibly may want to consider installing a 5 minute off cycle time delay, or possibly your existing thermostat may have one built in that needs to be set...

    Next time, cover the coils with cardboard to block air flow. I'll bet it won't cycle. Probably low on refrigerant.
