Kelvinator air conditioner troubleshooting

Kelvinator air conditioner troubleshooting. When your Kelvinator air conditioning unit stops working, it may be a small issue. But it can also be something more major.

While some problems that are easy to fix can be avoided with regular cleaning and maintenance, such as regularly changing the filters and keeping the system clean from dust, there are other problems that might require the experience of a professional air conditioner technician in order to diagnose properly.

The problem could be small or large, so let’s look at common reasons why you may have an issue with your air conditioning unit and how to deal with each one before it becomes a larger problem.

Error codes can help indicate if your air conditioning system needs to be repaired or is in need of maintenance. Each error code has a meaning to help you understand the problem and what needs to be done to fix it.

Below are various troubleshooting tips for Kelvinator AC and their repair methods.

Kelvinator Air conditioner not cooling

If the air filter is clogged, the cooling capacity of the A/C unit will be greatly reduced. In addition, if the air filter is clogged, frost will build up in the evaporator coils. To prevent this from happening, it’s important to clean or replace your AC filter every three months or so; otherwise, you can do some damage to your system.

A defective compressor could be the cause of an unusual amount of noise coming from your unit. If this isn’t the case, you should make sure other more common parts are working correctly: the overload protector and compressor capacitor. If the compressor is defective, call in a licensed technician to replace it.

The run capacitor is connected to the compressor with wires. If the run capacitor burns out, the compressor will not run. To determine if the run capacitor is burnt out, test for continuity using a multimeter. If it does not have continuity, replace it.

Kelvinator Air conditioner fan not operating

Try turning the fan blade by hand. If the blade does not turn freely, this indicates that the motor bearings are worn out. If the motor bearings are worn out, replace the motor.

If the blade turns freely, test the incoming power to the fan motor. If power is getting to the fan motor, but it’s not running, this also indicates that there is a problem with its current circuitry and it should be replaced.

The relay board is responsible for supplying power to various components of the air conditioner, including the fan motor. If the relay board isn’t working correctly, the fan won’t run.

Oftentimes people make a misdiagnosis and start replacing pieces before checking if any other components are nonfunctional. If you’ve determined that all other parts are functioning normally and don’t need to be replaced, replace the relay board.

The blower motor may be burned out. First, make sure that the blades spin freely by trying them on another model before condemning the motor.

Unfortunately, if the fan is defective beyond repair then it must be disposed of or discarded as new. However, if a blade is broken or stretched out you can replace this component which may increase the longevity of your current blower motor.

Kelvinator Air conditioner compressor won’t operate

Temperature control boards are used to regulate the cooling and heating in refrigerators and freezers. If the temperature control board is malfunctioning, it can stop delivering voltage to the compressor.

The most common reasons for a faulty temperature control board are failing components such as the fan motor or capacitor, or a failure with the compressor itself.

When replacing any of these parts, make sure you first check that all other relevant parts of your unit are still working properly before replacing any controls boards.

When the thermostat is used for several years, the electrical contacts inside wear out and it becomes less reliable due to this failure. When this happens, the thermostat will not cut on the compressor motor but it may still turn on and off the fan motor.

The overload protects against a compressor burning out when it draws too much current. Over time, the overload can burn out. If a multimeter is used to test the overload for continuity, and continuity is found not to exist, replace the overload with a new one.

Kelvinator Air conditioner doesn’t turn off

The temperature control board provides voltage to the fan motor and compressor. This can make a beeping sound by itself because it is faulty.

If there is no problem with common components like the thermostat or temperature sensor, you have to check the temperature control board’s function.

The thermistor is a sensor that detects the temperature of the room. It is connected to the control board, which manages many functions of your device.

If your thermistor malfunctions, it will not carry any electrical current from one point to another. Without this electrical current, the compressor will continue functioning all of the time.

Kelvinator Air conditioner is noisy

The dual shaft fan motor has bearings that can be lubricated but will over time stop being properly lubricated by the factory oil. This will cause the blades to begin making more noise than you would like when the fan is running. In this case, it is advised that you replace the dual shaft fan motor with a new one.

When the compressor is wearing out, it makes noise. This isn’t likely to mean a whole new compressor is necessary but some professional check-up may be required, so have a wormed licensed professional handle the matter.

To ensure the blower wheel is secure on the motor shaft, wiggle it back and forth. If there’s wobbling, tighten or replace both screws. If the blower wheel still doesn’t feel stable replace it.

Kelvinator Air conditioner remote control not functioning

First, try replacing the batteries in the remote control. If installing fresh batteries doesn’t solve the problem, operate the air conditioner manually. If operating it manually doesn’t work either and you think there’s a problem with your remote controls, replace them.

The main control board has an infrared receiver that receives signals from the remote. If the infrared receiver is not working, there will be nothing for the remote to communicate with and it won’t work. If you suspect that the control board has issues, replace it.
