The relay actuated by the thermostat which starts and stops the compressor and condenser fan in the outdoor unit.
Yes a compressor will run the entire heating and cooling cycle, unless its in emergency heat in which case you will not have compressor operation. Defrost cycle is the AC mode except the outdoor fan is de energized to assist in the defrosting of the outdoor coil.
The contactor on the outdoor unit is probably stuck. Disconnect the power to the indoor unit, then disconnect the power to the outdoor unit and take a look at the contactor.
Do you need to shade your out door compressor unit in this S.Texas hot weather?
Your contactor in the outdoor unit is stuck closed.
Is it a central unit? check and see if the fan and compressor are running in the outdoor unit. The system may be low on freon or the compressor may not be running. It is best to call a qualified HVAC technician.
That tells me the problem is with the outdoor unit. Most likely a dead compressor or fan motor. Additionally, your indoor and outdoor units are not on the same breaker.
A stuck compressor contactor. Do not turn off the indoor fan until you have either shut off the breaker or pulled the fuses to the outdoor unit and stopped the compressor, or damage may result.
unit is most likely low on refrigerant due to a leak, or compressor in the outdoor unit is not running.
It is low of refrigerant which means you have a leak that needs repair. After the repair the unit needs to be recharged.
It could be off on a low pressure switch. You need to check if you have 24 volts to the outdoor unit at the contactor coil. If the contactor is not working the outdoor unit will get no high voltage to the compressor or fan. It could also be that the capacitor for the fan and compressor is blown.
