It will run continuously if the refrigerant charge is off. The compressor, condenser fan and inside blower fan should all run at the same time. If your thermostat shows that the unit will not keep up, it will not stop. If the unit used to cycle ok, clean outside coil, change filter inside and put a thermometer on the register closest to the air handler. It should be around 52-60 degrees F.
what causes compressor lockout in voager rooftop unit.
Dirty plugged or damaged condenser coil Damaged or worn out motor or compressor "Brown out" where the voltage falls below the allowed specified minimum. If you system runs on 220 volt power it will over heat and quit somewhere around 200 volts.
Typical causes of a compressor not running are: low coolant, blown fuse in compressor circuit, bad compressor, bad temperature sensor.
orifice
your condensor is clogged up, or your condensor fanmotor is not working, or your compressor struckup due mechanical problem inside of your compressor.
No oil in compressor - wether it works or not, it still needs that special ac oil -
pressure switch located on the accumulator
A leak, either the pressure line or somewhere in the compressor.
Improperly programmed programmable thermostat.
Bad clutch on compressor, unplug the wires from the AC compressor, replace fuse if doesnt blow fuse its in compressor, if blows then gounded wire
Open circuit breakers. Poor electrical connections to the compressor, thermostat or bad wires not telling relay to cut the compressor on. Elaborate
Have the refrigerant level in the A/C system checked. Rapid cycling of the compressor can be one of the signs that your refrigerant level is low.
