What does code F0 indicate?

The L3 error code in a Kolin inverter window air conditioner typically indicates that there is a problem with the unit's compressor. The compressor is an important component of the air conditioner that helps to cool the air in the room by compressing and circulating refrigerant. If the compressor is not functioning properly, it can cause the air conditioner to stop working or to produce cool air at a reduced rate. Some possible causes of an L3 error code in a Kolin inverter window air conditioner include a faulty compressor, a malfunctioning compressor relay, or a problem with the unit's power supply. To troubleshoot the issue, you may need to perform a diagnostic test on the compressor or contact a professional for assistance.

Several issues could cause your condensing unit not to run. A manifold gauge set is required to diagnose if the problem is on the refrigerant side or the electric side of the condensing unit. From there the system can be diagnosed properly. Or you can use a voltmeter first and start at the fuse box and check the circuit breaker and test for power going out to the unit.

The compressor is not kicking in I need to know the right size and replace it

They are in the user manual, or on the panel by the control board.

tx valve problem blockage
have it properly diagnosed by an ac specialist
check consensor fan is running is separate fan to inside fan

It sounds like your unit is low on freon or the compressor is not kicking in. If the compressor kicks in you can hear it turn the unit on fan only or turn the thermostat off then turn the unit to demand cool you should hear a hum even vibration when the unit kicks in. If there is no audible hum ect... your compressor is probably not kicking in. The selector switch the temp switch the capacitor for the compressor or the compressor its self could be bad. good luck if you need to know how to test any of the above let us know

Do you have an amp meter? and volt meter. Are you sure that the compressor is getting power? The click may simply be a relay closing but no power. Check both sided of the relay. You will need to trace the power and make sure that the compressor is getting power. Then check the amps to see how much power it's pulling.

possibly have a capacitor out on the compressor side of the a/c Since the unit works and its only blowing air the compressor isn't kicking in. The capacitor boosts the compressor to activate the compressor. I would have the capacitor to the compressor replaced first before going any further.

Good luck on your repair

sounds like the compressor is having trouble starting. this could be the start components or the compressor itself. if the fan is running when you hear the "kicking in" noise it is you compressor, they are generally PSC motors, that require a capacitor to start, the capacitor could be bad, or the compressor may need a start kit added to it, they are available to the public at most appliance parts houses, you will need the model and serial number of the unit to select the proper one.

You have either a faulty thermostat, dirty condenser and evaporator or a faulty run capacitor. Need to service soon before the compressor is damaged. Sea Breeze
