Most a/c's have a 5 minute delay before the compressor turns on and they will do the same when changing from cooling or heating to cooling.

I have a Dometic 15K roof Ac on my FW. After the AC reaches therm temp, the compressor and the fan turn off, but the fan starts right back up again and runs until you set the thermostat on off.


That is normal operation, only the compressor cycles, the fan stays running to keep air circulating for better temp control. Otherwise the rear of the space could get 5 degrees warmer than the front

I have a digital Honeywell thermostat that has a blinking snowflake. When the thermostat is on auto mode it does not turn on. When I turn the thermostat to fan I can feel and hear the air blowing out of...


If the thermostat has a blinking snowflake then it is in time delay mode which sometime can take between 5 to 7 minutes before it will turn the AC and Fan On......Then it will go to a solid snowflake.
When you turned it to fan On it starts the Fan right away..... After the snow flake has went to solid check to see if the fan is running and then look outside to see if the Fan Blade is turning on the AC..... The fan blade comes on the same time as the compressor does. Then with the fan running hold your hand above the air stream above the AC and if you can noticeablely feel warm to hot air comeing out the Top then the compressor is running also. If the outside unit is not running I would check to make sure the Main Breakers are turned ON.... After the AC has ran for a few minutes feel the copper lines that go into the house the smaller line should feel warm to hot and the bigger lines with insulation on it should feel cool to cold and sweating with beads of moisture on it..... That is a quick test to see if the unit is working properly.....If you have a Thermentor and can Check the Temperature of the Return Air and the Supply Air .. You should have about 20 Degree F Between the Supply and Return........ 75* Return - 55* Supply would Equal 20* TD Across the Coil......
That is about all you can do to check on your own....... If the compressor is not coming on or the lines are not the temperature difference then you will need to get professional help for your Air Conditioning System..... Goood Luck Hope this Helps.........

RV Air conditioning not working properly


IF YOU HAVE A ENERGY SAVER SETTING ON TSTAT SET TO OFF THAT WILL KEEP FAN ON WHEN COMPRESSOR IS OFF. REMOVE LITTLE THERMOSTAT WIRE IN FRONT OF COIL WHERE FILTER IS , BE CARFUL NOT TO BEND IT IN HALF IT CONTAINS GAS IN IT MOVE IT SLOW ,ITS ABOUT COAT HANGER THIN OR HAS A BULB AT END . CARFULLY STICK IN WARM WATER GLASS TO SIMULATE HOT TEMP. SEE IF IT STAYS ON. NOTE BULB HAS NO WIRES ON PROBE. MOST ARE ALLUM. OR COPPER. IF YOU ARE NOT SURE WHAT YOU ARE STICKING IN WATER THAN HOLD BULB IN YOUR FIST CLOSED TO HEAT UP BULB IT WILL WORK THE SAME.

Fan cutting on and off every 5 mins


The only thing that is going to but the fan off is the thermostat. When the fan stops, immediately check the thermostat on the wall. See is there is power between the B terminal and the GH terminal. If none, then replace the thermostat. If there is, then replace the control board in the AC. That means that the fan relay on the printed circuit board is weak.
