If that is of no concern to you... then look in the manual about how to adjust the cut-in pressure. The cut-in pressure is what controls when the compressor portion turns back on. There is often a set screw that controls this.
Problem #1:Outdoor condensing fan motor has stopped running. This problem
could be caused by a bad motor run capacitor. If
your motor capacitor is not the problem, then more than likely you need a new
motor. Is the fan blade tight, stiff or hard to turn? If the fan blade is hard
to turn then you probably need a new motor.
Problem #2: Air conditioner compressor will not start. When power is applied
to the air conditioning outdoor unit the fan starts, but you hear a sound like
the compressor is trying to start, "UGGG"..., for about 5 to 10 seconds and then
all you hear is the outdoor condenser fan run. The compressor is locked and will
not start. What is happening is the compressor is trying to start, but because
the compressor motor is locked it tries to start for a few seconds and then
because of the high amperage being drawn goes off on internal overload. The
internal overload protects the compressor windings from overheating and burning
up. I see this many times during the start of the air conditioning season. Some
compressors just have a hard time starting after sitting all winter long. Some
compressors are locked up so bad that I can not start them and must tell my
customer that they need a new compressor . Many
times I can get the compressor started again without having to buy a new
compressor or new air conditioning system by using the device that is called, "Super-Boost." I keep two or three of these on the truck. They
have saved many of my customers from having to buy new air conditioning systems.
could be a thermostat problem but even more likely the contactor on the unit outside is stuck. In order to change this part you will have to get in to the outdoor unit. The contactor is the automatic switch that the thermostat energizes when the thermostat calls for aircond. The location of the contactor is in the outdoor unit (electrical section) and where the power will tie in to the unit. It is a little box looking part with terminals where most of the wiring connects. If the contacts are welded together the outside unit will not shut off. If you tempt to replace this part, make a diagram of all the wires connected to it before you take any of them off. Turn off all power to the outdoor unit before inspecting.
Thanks for your detailed information. But solution is very simple. The compressor contactor in out door unit. Struck. And hence, when you power on, without indoor commanding, the out door starts running.
Replace same type Contactor relay (In out door unit) immediately. Hope, it's helpful.
THE OUTDOOR UNIT HAS A CONTACTOR WITH THE CONTACTS WELDED TOGETHER THE CONTACTOR CONNECTS TO THE COMPRESSOR AS IT TYPICALLY PULLS A SURGE OF 20 -30 AMPS OR MORE..WITH THE INDOOR UNIT IN FAN ONLY THE COMPRESSOR SHOULD NOT BE RUNNING. THE CONTROL WIRES GOING TO THE UNIT HAVE 24 VOLTS TO THE CONTACTOR TO PULL IN THE CONTACTS TO SUPPLY 220 TO COMPRESSOR.
feel the compressor. if warm then it is being powered up and symptoms point to a compressor fault.
it is also possible that the compressor start device is faulty. remove cover over compressor electrics and check for any distressed componants
