I have an electra split unit a/c. A red light is on with a sign like an S with two lines. What does it mean? thanks

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.

Indoor unit faults = CH04 or C4
Fascia LED's
- RED = None
- GREEN = 4 Flash
Contents = Drain Pump / Float Switch
Case of Error = Float Switch Open Circuit (High Level Water Alarm)
Indoor Status = Off

clean your condensate drain line you can do this with a shop vac,

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.

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?

i would try looking at the out door breaker for your condenser. you may have a problem with your compressor, or fan motor.

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

Hello rfrizzell,

My unit is giving me the same alarm. If you have found the solution, please email me at [email protected]

Thank you very much.

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.
