dirty coil , cloged filter, low freon ,clogg drain, stuck reversing vavlue or cloged condensation drain.
The big question is which coil are you referring to? A couple of causes are 1-Low on freon 2-Filter dirty and not enough air flow across coil.
air conditioner condenser coil icing up
I would say that nothing causes a coil to overheat except for a bad coil, replace the coil and see what happens.
When your air conditioner runs during the summer, air blows over the extremely cold cooling coil, through the filters and into your house. When the air moves over the coil, it deposits most of its heat into the coil, meaning that it's cooled down when it moves into your house. If you have a problem with your air conditioner, either as a result of poor airflow (usually caused by dirty filters), improperly charged refrigerant or even the outside temperature, the hot air crossing the coil will not be able to deposit enough heat. As a result, the coil stays really cold and the condensation on it freezes.

A dehumidifier is a refrigeration system just like you home fridge or an air conditioner. The evaporator coil cools the air as the air is blown through the coil. This lowers the temperature of the air and thus decreases it's ability to hold water vapour. The water vapour condenses in the cooler air and drops out lowering the overall humidify of the air. When the air flow is restricted or too cool or the humidity is extremely high the water is not carried off of the coil and it condenses on the coil and then if the coil is cool enough the water will freeze forming ice. It is a simple matter to fix, just shut off your dehumidifier, let the ice melt and then put it back in service again.
There are a couple of things that cause your AC to freeze up. If your indoor coil is icing up you: 1. Have a dirty filter 2. Have a system low on refrigerant 3. You have a blower that is not providing enough air across the coil 4. You have set the thermostat too low (below 70 degrees Fahrenheit, setting the AC lower does NOT cool the room down faster)
What causes no power to coil pack in 1998 dodge stratus ?
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.
No, you don't. Your AC's inside unit contains the evaporator coil that cools the warm air blown over it. This causes condensation to form on the coil, just like how water droplets form on a cold glass of water on a hot day.
The coils can be cleaned using a coil brush and foaming coil cleaner. These items are available at www.appliancepartspros.com.
