Emerson Air Conditioner Not Cooling. Emerson Air conditioning units are now a popular trend within homes around the country. It’s no secret that many parts of the country experience very hot summers and temperatures like these.
Emerson air conditioning units tend to be used more often than not on the hottest days of summer leaving some homeowners having to replace part or all of their Emerson AC units.
If you’re experiencing problems with your Emerson AC not cooling properly, it could be for one of a variety of different reasons. When you’re aware of some common AC problems that may arise at home, you’ll be more prepared to handle them should they occur.
Emerson Air Conditioner Not Cooling
We discuss some problems with Emerson air conditioners when they do not cool.
Problem With Run Capacitors
Connected to the compressor with electrical leads are the capacitor and the compressor. If the capacitor fails, the compressor will not be able to work properly.
Multimeters can be used to test the continuity of the capacitor to determine if it has failed. As long as continuity is present, this indicates that your unit can still be used; if continuity is not present, you may need to replace it.
Issue With Thermistor
The thermistor is a component of the control board that detects air with temperature. The resistor value of the thermistor might change in concomitant with the air temperature.
If the air temperature is high, the resistance value will reduce. As to determine whether it’s faulty, use a multimeter to check for continuity.
If the thermistor isn’t doing its job correctly, or if the resistance doesn’t alter with a change in temperature, replace it right away because it might lead to some dangerous results like failing to maintain the refrigerator’s ideal room temperature.
Thermostat With Temperature Control
The thermostat controls the temperature of your home by turning the ac on and switching its power off periodically. If the thermostat isn’t working, it may be set too low in which case you need to reset it to maintain a comfortable environment within your home.
Another problem associated with a malfunctioning thermostat is that its circuitry may have been damaged due to corrosion or electrostatic discharge-the latter being something that happens when connecting devices for example. The solution for this issue is then to replace the current thermostat with a new one.
Defective Main Control Board
The main control board regulates the voltage of the fan motor or compressor. Unless your unit is old or damaged, it’s possible that the motor or control board is not working properly because you may have installed an old unit, bought a defective product, or a part may be missing from your air conditioner.
When in doubt and whenever possible, replace all malfunctioning parts with new accessories that were bought from an authorized dealer so you can guarantee quality replacements when repairing your air conditioning unit.
Faulty Thermostat
The thermostat monitors the temperature of the air. It sends a signal to your system’s components as long as it keeps receiving an input.
In other words, when the air gets too hot, it turns on that switch and provides power to the air conditioner which rots down and cools back down thanks to the fans and compressor until the next time the heat is activated.
If your thermostat is defective, it will not send a signal, so all of your unit’s electrical components will shut down, leaving you without cooling relief this summer.
Use a multimeter to test continuity in cooling mode. The air conditioner won’t work if there is no continuity, so we need to get someone involved in reconnecting those wires that have come disconnected from one another.
Air Filter Malfunction
A clogged air filter prevents air from flowing properly through the air conditioner. As a result, the air conditioner loses most of its cooling power. In addition, if the air filter is clogged, the evaporator coils will frost over.
To flush a clogged air filter, try to clean it with a nozzle for compressed air or a similar tool meant for that purpose. If cleaning it is not possible, replace it with another one that’s in good condition.
Error In Compressor
Your central air conditioning unit may have a defective compressor. This does not usually happen and you should not replace the compressor before finding the more commonly defective component, such as an overload protector or a compressor capacitor.
If your unit runs too slowly when it is normally powerful or during hot and humid weather, a problem with your system’s compressor could be to blame. You should let a licensed technician handle replacing the old one since they are experts in installations of this kind.
