My outdoor unit fan rotates slowly and compressor trips after 3/4 minutes

14.2.2 To Make a Diagnosis1 Timer LED starts to blink and the unit automatically stops the operation.
2 Press the CHECK button on the remote control continuously for 5 seconds.
3 "- -" will be displayed on the remote control display.
Note: Display only for "- -" (No signal transmission, no receiving sound and no Power LED blinking)
4 Press the TIMER ? or ? button on the remote control. The code "H00" (no abnormality) will be displayed
and signal will be transmit to the main unit.
5 Each press of the button (? or ?) will increase error code
number and transmit error code signal to the main unit.
6 When the latest abnormality code on the main unit and
code transmitted from the remote control are matched,
Power LED will light up for 30 seconds and a "beep" sound
(continuously for 4 seconds) will be heard. If no codes are
matched, Power LED will light up for 0.5 seconds and no
sound will be heard.
7 The breakdown diagnosis mode will be canceled unless
pressing the CHECK button continuously for 5 seconds or
operating the unit for 30 seconds.
8 The LED will be off if the unit is turned off or the RESET
button on the main unit is pressed.

Note:
"O" - Frequency measured and fan speed fixed.
The memory data of error code is erased when the power supply is cut off, or press the Auto Switch until "beep" sound heard following by pressing the "CHECK" button at remote controller.
Although operation forced to stop when abnormality detected, emergency operation is possible for certain errors (refer to Error Codes Table) by using remote controller or Auto Switch at indoor unit. However, the remote controller signal receiving sound is changed from one "beep" to four "beep" sounds.

The unit is overheating and tripping the internal overload of the compressor. Clean outdoor coils.....check outdoor fan to see if it turns or is siezed......possible bad Start/Run Capacitor which is a very common failure on condensing units......possible bad fan motor need replaced! Unit compressor can be cooled with a water hose to get it to reset the internal biometalic high limit switch that is located in the hermetically sealed compressor!

Is the indoor unit operating? If no turn the fan from auto to on at thermostat. If the fan comes on, that is a sign that you have 24volts
present on thermostat side.

Turn AC unit off outside,turn the thermostat as low as it will go. Open the electrical panel to the outdoor unit. There is a contactor located in the unit, push the plastic bar in the middle of contactor. If it pushes
in, you have low voltage wiring problem from the outdoor unit to the
indoor unit.

If you are skilled or know somebody that is with electrical, turn the power back on to the outdoor unit take a non conductive object and
push the contactor in, the unit may start. If it doesnt start,check the
breaker for the ac unit to make sure it is not tripped.

If the breaker is not tripped and the condensor fan comes on and the
compressor does not come on and the breaker does not trip, then it
is very possible that you will need a new capacitor and while you are
at it put in a hard start kit.

This unit according to you, still should have 2 years left on the compressor warranty.

First thing to do turn off the breaker in the electrical panel, then open up the AC outdoor unit, including the disconnect box, that should be mounted on the wall near the outdoor unit. Go thru and tighten all of the screws and wire nuts, look for burnt wires, while you are at it.
Turn on the breaker and try again, if it still trips, then we look deeper;
pull the control panel off the outdoor unit and look for the contactor, this is where the power coming into the outdoor unit hooks up to. There will be a set of contacts in the control, check it out and see if the points are badly burnt,
If all off the wire checking still has not helped, it will more than likely be a bad condensor fan motor or a compressor, the compressor is the big black thing in the bottom of the outdoor unit, making sure that all power is turned off, pull the plastic cover off of the side of the compressor, there will be 3 wires, make sure none of them are burnt and touching the metal, if they are, repair the wire and test.
Try this and if you need to know how to troubleshoot to see if it is the fan motor or the compressor, just contact me back.
If this has been helpful, please rate me.
Contact me if I can help you any more.

sounds like you have a bad coppressor

The first thing I would check is the outdoor unit coil and see if it is restricted(dirty). If that is the case then you can wash it off with water(make sure you shut the power off to the unit first). If the outdoor coil is restricted and has little air flow thru it ,it can't get rid of the heat from the space and the compressor will draw over amperage and trip the breaker.
The next thing to check is if the outdoor fan is running. If the fan doesn't run it is the same as the restricted coil, it can't get rid of the heat from the coil. Check these things first then we can go from there! Thanks!!

first check the compressor amps and the condenser fan rotation are correct if ok check power come to the compressor without interuption (from control in the indoor unit)if the remote setting are ok correct voltage to the compressor may high pressure stop it or low pressure compressure overheat.and if this was repeated many time the best to change the compressor.

It sound like you have a direct short in the compressor ,Usually it means you have a bad compressor,but sometimes it could be a loose wire or bad outdoor motor. Ive installed about 10 of these units and still have yet to have a bad compressor.It could also be a bad circuit board in the outdoor unit.I wish I could narrow it down better but thats my best guess!Thanks ---Nate

Does the fan on the outdoor condensing unit come on when the compressor does? If so, Is the condenser coil clean so that the airflow from the fan can remove heat from the condenser coil so the compressor won't overheat and trip the internal overload compressor protection circuit? If yes then is the indoor evaporator fan working properly? If yes are your filters clear and evaporator coil clear so that adequate air is flowing over the coil to prevent the compressor low pressure protection circuit from tripping? If so is the refrigerant charge on the system correct- either overcharged or undercharged can trip the compressor protection circuit. By now you should have come across an explanation for your compressor short cycling. If I had to guess I would bet on inadequate airflow over the condenser coil do to a faulty condenser fan motor either not turning at all or turning for a few minutes and then stopping when it overheats. This is likely caused by an unsealed replacment motor being used outdoors and water/rust has accumulated over the winter season and/or the capacitor is bad (in this case the motor may be turning slowly backwards) or just plain old worn out. I hope this helps get you to cold air sometime soon GL!

-Start the unit.
-Press EMERGENCY OPERATION switch.3-minute time delay works.Test run operation operates for 30 minutes.
-Check voltage to terminal block of outdoor unit.Is there 12V DC between 2-1?
-If voltage is presenet check the wiring, compressor contactor outdoor fan motor and compressor.
-If no voltage check voltage to terminal block of indoor unit.Is there 12V DC between 2-1?
-If if voltage is present re-connect the continuity of indoor and outdoor unit connection.
-If no voltage replace the indoor electronic control P.C.
board.
-But also check the coil thermistor sensor and room air thermistor if this two is out of range it can cause the tripping of out door unit. It has the resistance of 8 to 10 k ohms at 25 deg c temp.
