How to Troubleshoot Samsung Air Conditioner Lights Flashing?

When it comes to Samsung air conditioner flashing lights, you have to consider the possibility of any of these causes:

1. Clogged or Incorrectly Fitted Filter

If the air filter is filthy (dirt-clogged) or wrongly fitted, the air conditioner will flash the filter indicator light. The blinking light is primarily red and so watch out for that.

Remember, your air conditioner won’t cool properly when the filter is clogged or faulty. So, you don’t need the indicator light to check that.


Inspect your air filter for dirt clogging. Samsung recommends replacing it every six months. Meanwhile, ensure the filter is correctly fitted. 

2. Frozen Coils 

If the air conditioner blinks red and green, the evaporator coils are likely frozen. In most cases, the evaporator coils frost over to indicate a refrigerant leak, which means this is something you should call a professional for. 


Power your air conditioner off and open the front panel to inspect the evaporator coils. If they are frozen over, call a pro.

3. Poor Airflow

Good airflow and filter light are pivotal to properly cooling and heating an air conditioner. The AC will malfunction if anything prevents your indoor or outdoor unit from properly circulating air and if the filter is clogged or the light is malfunctioning.

The AC unit won’t cool or heat properly and may present with a blinking light. The blinking light can be green or a combination of blue and red light.


Check for anything that could be blocking your AC. Indoor, remove any obstructing furniture or heavy curtains. And outdoors, clear any bushes and clutch. Meanwhile, ensure your AC is clean (dust-free).

4. Low Refrigerant 

The air conditioner may also flash green when the refrigerant (coolant) level drops. That usually is a serious issue since the AC won’t heat or cool when the refrigerant drops. The cause is often a leakage which an expert can help you fix.


Most ACs have a refrigerant meter that measures the refrigerant level. Once you suspect a refrigerant leak, call an expert. 

5. Electrical Fault 

Your Samsung air conditioner will flash its lights if there’s an electrical fault. That includes broken and loose wires, irregular power (or power surge), a malfunctioning PCB (Printed Circuit Board), and a damaged cord.

In most cases, the AC will blink green severally to indicate the fault, but it can also blink red, especially if the circuit board is malfunctioning.


If you have the technical know-how, inspect your electrical wiring for faults and observe the power cord for damages. However, if you cannot do it, especially inspecting the PCB and filter light, request an expert inspection of your wiring.

But first, check the circuit breaker for possible tripping (due to a power surge) and reset it. 

6. Failing Compressor 

If the reason your AC blinks red has nothing to do with a faulty filter, it’s likely to be the compressor. It’s highly probable that the compressor is failing, forcing your AC to work double hard to maintain a comfortable indoor temperature.


To be sure that the problem is the compressor, look for the error codes on your Samsung AC. An error code like E403 indicates a compressor issue. So, you should have an expert check the compressor and replace it if it’s defective. 

7. Incorrect Air Conditioner Installation 

Lastly, your Samsung air conditioner could blink its light if it’s wrongly installed. That doesn’t necessarily mean that the unit is faulty, but it indicates you’ve to check it and probably reinstall it.

Note that an error code (201, 556, EA, 203, or any other) may accompany the blinking light.


Note the error code and use it to consult an HVAC pro.

Types of Blinking Lights by Samsung Air Conditioner and Their Troubleshooting

Here are some notable blinking lights on Samsung ACs and their interpretation and troubleshooting:

1. Samsung Air Conditioner Blinking Green Lights

While a Samsung AC displays a solid green indicator light to show it’s running smoothly, a blinking green light is a sign of a fault. The fault could be any of the following:

  • Power surge – Once there’s a power surge, enough to trip the breaker, the AC will start blinking green. So, check the breaker box to reset the breaker if it’s off. 

  • Blocked outdoor unit – If anything is blocking the outdoor unit from proper air circulation, the AC will flash the green light severally. So, you need to check the outdoor unit and remove any obstructions. 

  • Refrigerant leak – If the reason for the green flashing LED is not an electrical fault or blocked outdoor unit, it’s likely to be the refrigerant that needs refilling. So, call an expert.

2. Samsung Air Conditioner Blinking Red Lights

Several issues could result in your Samsung air conditioner flashing its red indicator light. The commonest ones include: 

  • The AC’s outdoor unit is off – If your outdoor unit (especially the compressor, fan, or condenser) is not running, the AC will indicate RED. So, you need to inspect the outdoor unit. 

  • Dirty air filter – As mentioned earlier, the AC will indicate RED if there’s an issue with the filter. So, check it for clogging and clean it. 

  • Tripped-up breaker – Remember, an electrical fault (in this case, a tripped breaker) can cause the red blinking. So, you need to check it and reset it. 

  • Faulty circuit board – A malfunctioning circuit board that you should replace can force the AC to blink red. 

3. My Samsung Air Conditioner Red and Green Light Flashing

The Samsung air conditioner rarely flashes the red and green LED simultaneously, but it can happen. If it does, it’s likely to be due to one of these causes: 

  • Clogged condensate pipe – Once the condensate pipe clogs, which you can tell by a leaky unit, the AC may flash the red and green LED. If so, have an HVAC pro check the condensate pipe. 

  • Frozen coils – Frosted-over evaporator coils may force the AC to flash red and green lights. If so, also have an expert check the unit. 

4. Samsung Air Conditioner Red + Green + Blue Blinking Lights

Sometimes the Samsung air conditioner flashes the red, green, and blue lights simultaneously to indicate an EEPROM error. The EEPROM (Electrically Erasable Programmable Read-Only Memory) error pops up when the outdoor unit’s main chip or indoor PCB fails to get any feedback from the AC’s EEPROM chip. 


Since the blinking light indicates an EEPROM error, you should try resetting your AC. Just power it off and unplug it for a few minutes. If the error won’t erase after resetting, consult a professional.
