AC went out after getting unplugged?

Hello again. Hoping to get some more help. It's been a while. So I plugged my rv into my 30 amp plug at the house & turned on the front AC to see if it would cool & get things ready for summer.. while it was running. My buddy & I went to check the 50 to 30 plugs(I had to replace the 30) to see if they were getting hot. They were fine but after I put them down it got unplugged & my AC went off.. so before I plugged it back in I walked inside & turned off the thermostat. We gave it a few minutes & I walked back out plugged the rv back in & when I went to turn the AC on nothing happens... the thermostat comes on but neither ac units come on.. no hum.. no fan ... nothing.. I checked the fuse at the breaker inside & it looks good. Any suggestions on what or where to look? Thanks

    Does the microwave work?

    Check the breakers in the RV--cycle them off and then on.

    Did you monitor the voltage while running the air conditioner?

    What kind of thermostat? What kind of RV? What kind of a/c? What kind of shore power?

    We'll need a little information to be of any assistance.

    Reset the circuit breaker. Did you unplug while unit was running? Bad idea!

    A/C's have a ten min time delay before they will restart. every time you interrupt the power it must reset and start the clock over.

    Thanks guys.. 1st off it was an accident but yes it got unplugged while it was on.
    Also it is a 1996 allegro bay 34 ft class A motor home. With the dreaded 4 button dura-therm thermostat with 2 durotherm Ac units. Yes I flipped the breakers off & back on a couple of times & gave it about 30 minutes to reset & its still not doing anything.

    I will check the microwave & see if it works.
    & no I didnt have a voltage meter checking voltage when I started it up... it was running good for about 10 minutes until it accidentally got unplugged lol

    Ok so my lights are working & my micro wave is working but my ac is still not coming on.. also my slide out is not working but not sure that is caused by same problem.. I only have 1 house battery on right now. Not sure that matters. Its been a while since i used the slide out

    Slide out is 12 volts DC.
    Check thermostat for the correct position and setting.
    Check 120 volt output at the AC power distribution center on breaker.
    Check the neutral connection.
    Any noise at all from AC unit?

    Its not 10 minutes. The compressor Time delay is about 2 minutes 45 seconds. The Fan on Auto will usually be 1 to 2 minutes. If you are concerned about the AC not coming ON, just turn the tstat to FAN instead of Auto. The fan will come on within 30 seconds. If NOT, then check your breakers. Doug
