Most likely a bad thermostat or refrigerant leak.
;slow blower;low on freon;dirty filter.
The most common reason for an evaporator coil to freeze in a refrigerator is restricted airflow due to a clogged air filter or blocked vents. Additionally, low refrigerant levels or a malfunctioning thermostat can also lead to the evaporator coil freezing. Regular maintenance and proper ventilation can help prevent this issue.
No,most likely your evaporator / filter is dirty or your system is low on freon.
The evaporator coil is starving for refrigerant. Basically what is happening is the refrigerant pressure/temperature is low enough to cause the humidity in the air to freeze on the evaporator coil. This cause a air restriction, hence insufficient to no indoor air flow. Usual common cause is a low charge of refrigerant or a restriction in the metering device, although not the only possible causes.
The water in a water cooler dispenser freezes when the temperature drops below freezing, causing the water to solidify. This can happen if the cooler is placed in a cold environment, if there is a malfunction in the cooling system, or if the thermostat is set too low.
A dirty cabin air filter in your car or a dirty air filter in your home can reduce the amount of air that goes across the evaporator. When that happens, you aren't pulling enough heat out of your home/car and the AC lines including the evaporator, can freeze and completely block the air.
Water freezes at 32 degrees Fahrenheit, so the water would have to be 32 degrees cooler on the Fahrenheit scale in order to freeze.
It may be over-charged (too much refrigerant) or not enough air across the evaporator coil. Actually it could be under charged. The pressure is lower during the night since it is cooler outside. If the pressure drops on the low side below 56-58 pounds correlates with lower than 32 degrees making the humidity in the air freeze to the coil (evaporator). In all likelyhood you need a slight charge of R22. If the filter is dirty, again it could be like the 1st answer not enough air over the coil. But I will stick with my theory.
cold
An AC evaporator can ice over due to a few key factors, primarily related to low airflow or insufficient refrigerant. When airflow is restricted—often due to dirty filters, blocked ducts, or a malfunctioning blower motor—the evaporator coil can become too cold, causing moisture in the air to freeze on its surface. Additionally, low refrigerant levels can lead to lower pressure in the evaporator, resulting in temperatures that drop below freezing. Both situations can disrupt the normal heat exchange process, leading to ice buildup.
the suction pressure drop and the evapo freeze
Yes, there are companies that will freeze you and keep you in a cooler. Problem is, no one now knows how to defrost you in the future without killing you.
