My compressor doesn't turn on. My thermostat

My compressor doesn't turn on. My thermostat turns on the fan when set to auto, but it doesn't seem to trigger the air conditioner itself. I've checked the breaker...is there some type of reset switch or anything in the compressor itself? The unit is an Armstrong Concept 1000.

There should be a disconnect outside near the unit. Check the breaker or fuses there. You can also remove the cover where the power goes into the outside unit and see if the contactor pulls in when you set the thermostat to call for air. Does the fan for the outside unit come on? If the outdoor fan and the compressor are both not coming on it would indicate that the unit may not be getting power because they both work off the same contactor. It could also be problem with the capacitor. When you check the contactor, if it isn't pulled in then your contactor could possibly be bad but there may be a couple of safety switches that keep the contactor from pulling in also. Let me know what you find and I can offer more advice based on that.

My domestic rv ac unit reaches the temp setpoint and the compressor shuts off but not the fan, it just keeps on running. Is this normal or should the fan shut off also?


Set fan setting to auto and not high or low setting. Fan will cycle with compressor after setting set to auto or " au" if a digital thermostat.

Cool will not come on when it's set in auto mode


A thermostat is only a switch, nothing more. It's job is to cut on and off the cooling/heating equipment based on a preset temperature setting. It sends 24-28 volts to a contactor or relay which does the actual closing (turn on) or opening (turn off) the power to the compressor or furnace, and that's all it does. There could be a problem with the other parts of the system. When the space temperature exceeds the preset temperature the thermostat should provide 24-28 volts to the compressor contactor, to start the compressor. The "Auto-on" switch on the thermostat controls the fan only. If there isn't 24-28 volts from the thermostat to the coil of the contactor, the compressor will not operate,

Do Goodman Split System fans turn off when the compressor shuts off? Is there a setting so the fan stops when the room reaches the desired temperature?


That is the job of the thermostat, but only if the "Fan-on/auto switch is set to auto. Look on your thermostat for the switch.

Sharp AF-M808X air conditioner. suddenly there is only fan air movement. there is no longer any cooling; turning the thermostat knob to a higher level doesn't "kick in" the coolant. but...


Simple test: the thermostat in your unit is electromechanical - unplug the unit from the mains, take it out and measure the resistance between the 2 electrical contacts, if it doesn't goes to near 0 when you turn it even a little bit then it's defective and it will have to be replaced.
If the resistance does indeed goes to near 0 then the defect is in the AC system. Another simple test: open the casing of the unit and put your hand directly on the compressor; now turn the thermostat button. If it doesn't vibrate then the starting capacitor of the compressor has failed and it will have to be replaced with a similar one.If it vibrates then the cooling circuit has got a leak and all the fluid has been lost. For that you will have to call a pro that will solder the leak shut and refill the circuit with the appropriate fluid - only he will have it, it's not sold on the customer market.

Neither.
The fan should run in the 'auto' position.
If it runs (on hi and lo settings) then I doubt if anything is wrong with the fan motor.
I would think your thermostat is bad and needs replacing.

Refrigerator does seem like its working right


Your refrigerator compressor is either pumping or it is not. Set the refrigerator to low temperature, pull it out and listen for a while to see it the compressor is coming on. If it is coming on then there may be a freon leak or the internal coils may be iced up. If it is not coming on, then either there is no power to the coompressor, or the compressor itself is defective. Use a voltmeter at the compressor to check for voltage. There is also an add on device to start stuck compressors from your local HIVAC jobber store.

Fan does not turn off even after disconnecting


Are you referring to the fan on the external mechanism, or the internal air handling fan?
The external fan is not controlled by the internal thermostat. it is controlled by the thermos-witch of the compressor. The external fan may or may not run when the motor is operating. it depend totally on the temperature of teh compressor, and not the internal thermostat.
It the internal air handling fan is running continuously,it may be a a problem with the fan setting. check if the fan is set to 'ON' instead of 'AUTO', and correct it.
Incidentally the fan operation I described, is for modern, energy efficient heat systems. This is a energy saving design incorporated in all heating systems including automobile radiator fans.

Compressor starts and doesn't stop


Relay for the compressor may be stuck ( Contacts welded) both the fan and the compressor should operate at the same time. Have the relay(s) checked and possibly replaced.

Ptac fan keeps blowing


Try setting the fan control to "AUTO" this will cause it to cut out with the compressor.
