It means there is power being supplied to the unit. The symbol is of the sine AC voltage.

FUJITSU Inverter wall mounted split air conditioner Model : AST12LSBCW not working, flashing lights


This is a "PFC circuit abnormal" in the outdoor unit meaning that the outdoor controller board is faulty. Try turning the machine off at the isolator switch for 10 mins, then back on to see if the error resets. If not you will need a new controller PCB.

Red light flashing on charger


A red light indicates the charger is charging the battery, an amber light means it has switched from fast rate charging to trickle to keep the battery topped off, and green would mean the battery is completely charged. But don't be fooled waiting for green, many times the charger will only be on green for a moment before changing to amber and keeping the battery topped off.

Flashing can be a sign of a problem on some chargers.

A rapid flashing red can on some chargers indicate a bad or shorted battery, or a bad battery contact in the charger itself. If in question, try a different battery on the charger or compare with another charger to determine if the blinking is normal.

Best regards.

This is not a split system a/c unit guys. Look at the picture. The blinking light means the air filter may need cleaning. Reset power to turn it off.

My split system was working fine. Tuned it on and wont work. remote is working. do I need a tec to come and look at it.


Before calling a repairman, check your self by a volt meter.Confirm power is there in your indoor unit.If there green or red light in the unit displayed or not. If yes, try with your remote. If not check your PCB for fuse blown. Replace the fuse and check again.
Indoor unit display light and no work by your remote means communication error between your remote and unit. Try with other remote. If o.k. replace your remote. If not, problem with PCB receiving sensor. Repair it. Thanks and hope it's helpful?

ELECTRA SPLIT UNIT AIR CONDITIONER - NOT WORKING


If the outdoor fan is the one you are talking about, it will not cool when it is not running. It sounds like the motor is over amping and going out on interan overload. You will have to change the motor for the fan outside on the condensing unit

Senville Mini Split Error Code


thanks for your question, you will need a set of gauges on the unit to determine if the unit came precharged, if it didn't then you will need to vacuum down the unit, at least three times, after each time release a little 410a into the system them evacuate again, 410a is bad for drawing moisture, did you put an in-line filter dryer on as well ? after you find out about the freon level, then look at the name plate rating for amount of 410a needed, before adding the freon, use nitrogen to leak check the system, then weigh in the proper amount of 410a, unit should run really well after that, hope that helped, thanks again for your question, please feel free to come back if you have any more questions, thanks, mr.grzz

Thank you. there are some other signs i don't know about.


The black triangle means AUTO, means the fan speed adjust by itself from high-mid-low speed depending in room temperature but the unit is cooling for this function the same COOL mode. Plasma is in the remote control but it never mention in the manual.
If the unit dont cool check your temperature setting and mode setting it should be in cool mode and temperature setting should be 18C. But if still don't cool check some error code like blinking light at the indoor panel check how many blink appears to get the correct error code.. If the light is blinking 3 times it means that the room air or coil sensor is defective.
