Flickering or dimming of lights of Air conditioners is a very common issue in-home unit.
ACS requires huge electricity for their cooling cycle to begin, and it often takes electricity from other appliances temporarily to start up.
This means an ultra-high demand on an already low power unit.
A 5% reduction in brightness is typical, which is not a signal for any of your worry.
The problem occurs when the lights constantly flicker, and one must take higher power outlets then.
Why Is My AC Light Blinking?
During a blinking light issue in your air conditioner, it shuts down the air conditioning as well.
All it blows is warm air and shows an issue with faulty wires or some circuit issues.
To correct it, (Works in more than 90% of cases )
- Switch off the circuit breaker
- Then, wait for a few seconds
- The unit will restore on its own
The Mitsubishi Aircon light blinking.
It is a sign of self-diagnosis and helps Mitsubishi Electrical customers to find a fault in their system automatically.
Just clasp them firmly back, and they will be good to go and will function normally again.
Blinking lights in Daikin AC
In Daikin AC, blinking light shows a fault or system auto shut for any number of reasons.
When the system has some fault, and one sees a green light blinking, simply press and hold the Cancel button for about 4 to 5 seconds.
Resetting the Air Conditioner
The following steps are there for resetting the AC thermostat
- Begin by shutting down AC at the thermostat
- Turn off the thermostat from the AC unit
- Find the circuit breaker box for the AC unit
- When you find it, reset the circuit breaker
- Wait for 25 to 35 seconds
- Turn the AC thermostat again on
Panasonic Aircon Blinking
Most of the blinking issues occur in Panasonic due to faulty wiring issues.
As this problem occurs, aircon is bound to function improperly
So check all wires and cables inside the AirCon unit, and you will find a fault soon.
Fixing a flickering light when your AC is on
When an HVAC system starts to turn on, the amount of electricity quickly changes its route from light switches.
Though this happens for a brief second, the real problem occurs when it happens multiple times.
The real problem is when there is a multiple times flickering of light, and it shows a possible circuit overload.
The most effective and quick hack is to unplug other appliances that are using the same circuit or use a power plug that only powers an AC unit.
Even a neighbor’s Air conditioner can cause your home lights to flicker because of common transformers, which they both share.
Some most common Air Conditioners issues
- Air conditioning constantly running/ thermostat issues
- AC not switching on due to circuit tripped or a faulty thermostat
- Lack of any cool air indicating a problem with either the circuit breaker or faulty blower belt
- Hot air blowing endlessly due to lots of debris inside the dirty air filter
- The leakage in refrigerant/ water because of blocked drainage pipes or the faulty condenser
- AC unit turning on and off repeatedly due to clogged air filters now and then
- Condenser coil repeatedly freezing due to dirty air filters which make AC use twice the power than usual

Related Questions and Frequently Asked Questions (FAQ)
Q1.) What is the reason behind the blinking of my thermostat?
Answer: Sometimes, a light blinks during the AC operations, showing some issue with the system’s outdoor position.
Q2.) What is the related shelf life of Mitsubishi Air Conditioners?
Answer: Air conditioners have a probable lifespan of 10 to 15 years.
- It depends on many factors like use and maintenance
- Age can be less than a decade if one neglects it completely
Q3.) Why is the AC not so cold?
Answer: The most common reason is as follow –
- A lack of an adequate airflow
- Make sure; filters are not dirty
- Make sure there is no airflow over the evaporator coils
- Ice can flow on them
Q4.) What is the full form of EO SW?
Answer: Emergency Operation Switch
Q5.) What is the probable meaning of dry mode on my Mitsubishi Air conditioners?
Answer: The dry mode works when you only want your Air conditioner to work as a dry fan without any cooling.
As no cooling is there, the water vapor condenses in the evaporator.
Q6.) Why is my Mitsubishi Air conditioner not cooling?
Answer: The poor cooling is usually due to certain reasons –
- Insufficient refrigerant/ lack of service
- A leaking refrigerant, take it to a dealer to solve the issue
Q7.) Do all Air conditioners have a reset button?
Answer: Most, if not all, ACs have a reset button right there on them.
The button comes off as red and very small in size.
Or consult the instructions manual to determine the air conditioning and find the location.
Q8.) How to troubleshoot a Mitsubishi Air conditioner by ourselves?
Answer: Begin by checking the thermostat of the air conditioner and double-checking it’s working.
- See the condenser to check whether it is dirty
- Clean or change the filter
- Experts recommend doing the above step at least every quarter
Q9.) Why is my AC not working suddenly?
Answer: Anything happening suddenly is always a cause for worry.
But, this can also happen due to common mismanagement issues of Air Conditioners in general and not a cause of worry.
Common issues are wire tripping, a blown a fuse, and tripped circuit.
Q10.) What are the possible reasons if your air conditioner is running but not cooling the house effectively/ at all?
Answer: The most probable reasons are as follow –
The HVAC interior is not clean.
Clean the condenser and filters.
Mostly when these are so full of debris, a problem arises.
Q11.) What is the procedure to reset the Air conditioner window unit?
Answer: Do this in the following steps
- Press the reset button for around 5 seconds and release then
- The button is located right across the power cord
- Wait for 10 minutes to resume AC to its normal working condition
Q12.) How to troubleshoot a particular thermostat?
Answer: Try these tips to troubleshoot your thermostat effectively
- Most of the thermostats operate on batteries
- Begin by removing the thermostat cover and replace batteries if any need arises
- Check if there is any tripping of the control panel & check for any fuses or any wire contact
Q13.) What is the cost of AC Capacitor replacement?
Answer: $170 for an average HVAC Capacitor.
Generally, prices flicker from $120 to $250, including any extra installation rates.
Branded units are costlier and easily cost $400+.
Q14.) Why are the AC lights blinking on your car?
Answer: A pretty common issue
A/C magnetic relay for the clutch is the most common cause for this issue.
Find the relay in the hood and near the batteries and the fuse box cover.
Q15.) What is the reason when your Cool on mode is blinking in Honeywell thermostats?
Answer: Honeywell thermostats most often blink due to time delay for cooling.
This feature protects the compressor from any cranking.
One can see the heat on or snowflake indicator as well.
Q16.) Why did your Air Conditioner surge?
Answer: Most probable reasons are power-related.
Natural power surges like a bolt of lightning or manmade surge from electrical issues on Air conditioner units are common reasons.
Q17.) Why is the Air Conditioner unit flashing for a snowflake?
Answer: 2 blinking snowflakes means the thermostat is in T-Stat and also is in a delay mode for about 5 – 7 minutes.
Their position is to the middle right of the thermostat display icon.
This protects the compressor from sudden heat to cool operation changes.
Final verdict
An Air conditioner is a helpful electrical machine that keeps our houses cool from the outside heat or heats our houses during cold temperatures.
However, like any other machine, ACs require maintenance from time to time for avoiding to deploy any faults.
Most of the air conditioner-related issues come from lack of maintenance, which leads to filters overflowing with dirt and debris.
This means AC has to work double its normal power leading to electricity loss and other problems.
Electrical circuit tripping is also a common issue if your home does not have any proper wiring system.
This is true especially in the old houses where many other appliances also run in tandem with an Air conditioner and a power surge happens.
The best way is to use some proper guidelines. Other common issues with AC are technical issues like lights blinking.
The blinking shows some faulty wires as the sensors detect automatically. On the other hand, the thermostat blinking shows an issue with the thermostat.
Once again, 1 or 2 times, blinking is never an issue.
The issue only comes into reality when it blinks more than it should do otherwise, showing an anomaly.
The ACS is there to work for 10 to 15 years. However, Poorly maintained AC units will end up having very little shelf life.
