Cooling Mode - Represented by a snowflake symbol. This setting activates the air conditioner's cooling function. Temperature Control - Typically represented by symbols like "+" and "-" or arrows pointing up and down. This setting allows users to adjust the desired temperature of the room.
Cooling mode is the most frequently used setting on air conditioners, represented by a snowflake symbol. It works by removing heat from the indoor air and expelling it outside, thereby lowering the room temperature.
The Snowflake: used for cold air or cool mode. The Raindrop: used for dry mode. This should be used when the conditions are humid, and temperatures are mild. The Arrows: usually means automatic mode.
Press the Mode button and select Cool. Step 2. After selecting Cool mode, you can also select the desired function, temperature, and fan speed as well. To cool more quickly, select a lower temperature and a faster fan speed.
Cooling: If you see a snowflake symbol, that means cooling. When this is on, you'll enjoy comfortable temperatures, especially in the heat of summer. Heating: Any sun symbol represents heat. Keep toasty in the winter by programming your air conditioner to blow warm air throughout your room.
Most AC remotes offer different modes such as cooling, heating, dehumidification, and fan-only. Look for the 'Mode' button on your remote and press it until you select the cooling mode. This mode is often represented by a snowflake symbol or the word 'Cool'.
Cooling Mode Symbols
Some thermostats will indicate the air conditioning is on with clear text that reads “AC On” or “Cool On.” Other thermostats may use snowflake symbols to indicate the same thing. Either way, it simply means that the system is in cooling mode.
Cool mode
This is the most common and usually the default setting when you first turn on the AC. This mode sends cool air throughout your room and is great for cooling down an area after a long, hot day.
To fix an AC not blowing cool air, ensure the thermostat is set to "cool" mode and the temperature is set lower than the current room temperature. Inspect the air filter as a dirty filter can restrict airflow. Ensure the condenser coils are clean and free of debris. Make sure vents are open and unobstructed.
Let your unit complete its current cycle before switching from AC to heat or vice versa. Wait for five minutes before switching from AC to heat to let the refrigerant return to its starting pressure. Avoid making drastic temperature changes; raise or lower the temperature a few degrees at a time.
These are the cool function and the heat function. As you've likely guessed, the cool setting is for air conditioning, and the heat setting is for warming up your home. While these settings are fairly straightforward, it's important that you understand where they are on your thermostat.
Sine Wave Symbol (~):
The most common representation of AC current on a multimeter is the tilde (~) symbol, which resembles a wavy line or sine wave. This symbol is often used to indicate that the multimeter is in AC voltage or AC current measurement mode.
1. Cool mode (snowflake symbol) A snowflake represents your AC's cooling mode. As the name probably already suggests, the AC, in this mode, will work to bring the room's temperature down rapidly.
The blinking "Cool On" means the cool cycle is in delay (5 minute by default). If it's continually blinking then either the thermostat is bad, or there's a short in the low voltage wiring that's causing it to reset everytime it tries to come back on (basically resetting itself over and over).
To change the temperature of an AC without a remote, locate the temperature control buttons on the unit's control panel. Press the appropriate buttons to increase or decrease the temperature to your desired setting. Some units may have up/down arrows or specific temperature adjustment buttons.
There are a number of reasons why your air conditioner might be running but not cooling. It could be an issue with the thermostat, the compressor, or the evaporator coils. Or, it could simply be clogged with dust and debris, which is preventing it from working properly.
Most units will have a snow flake or ice symbol for the COOL mode. This mode is used to cool the room and would typically be used during summer. The sun symbol represents HEAT mode.
In most situations, 78'F is the ideal AC temperature to save electricity. The U.S. Department of Energy advises keeping your home between 72° and 78° Fahrenheit to preserve comfort and a manageable electric expense.
AUTO is significantly more energy efficient between the two modes since the fan is only running when your AC is going through its cooling cycle. This takes less power, which is more budget-friendly, with some estimates showing you can save as much as $50 per month just by keeping your AC on AUTO.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
The ideal thermostat temperature in the winter is 68 degrees Fahrenheit when you're at home. Energy.gov suggests that 68 degrees is a good room temperature while you're awake at home but recommends lowering it while you're asleep or away.
Thermostat Issues
There are several things that can go wrong with a thermostat. For instance, it could be misreading the temperature, causing it to turn on and off at the wrong times. Alternatively, the batteries might need to be replaced, or the thermostat could be dirty, affecting its ability to function correctly.
