How to Easily Fix Your Air Conditioner

Thus, you need to maintain them in a top-notch condition to maintain their working efficiency. But, how do you identify errors in faulty air conditioners? How do you fix the problems? To help you out, this article discusses various ways you can point out defects in an air conditioner and the possible ways of solving the problem. Check them out.

The air conditioner runs continuously

If your air conditioner doesn’t shut off automatically, the fan relay might be stuck. The problem might also emanate from a loose wire connection or a faulty thermostat. To work on the issue, turn off the appliance from the circuit breaker and disassemble it to access the blower relay. Replace it if not working. Inspect the heat sensor too before you reassemble the air conditioner. Use a multimeter to test its resistance. If working, wipe the accumulated dust using a brush or compressed air. Also, you may need to recalibrate its readings to improve its accuracy in detecting temperatures.

Air conditioner not blowing cold air

An air conditioner may fail to blow cold air if its filters are clogged by dust and other debris. If your air conditioner can’t blow cold air, there could be a problem with the thermostat, vents, or the filters. However, experts from advise that the problem might go beyond the defective thermostat to include the fan motor. In that case, you should disassemble the appliance and check if the thermostat is fixed correctly. In some cases, you might need the assistance of an experienced servicing professional. The expert will identify the cause of the problem and provide a solution. It is thus essential to clean and replace the filters regularly to prevent such issues in the future.

Air conditioner fan not working indoors

The fan will fail to work due to a lack of power and accumulation of ice on the evaporator’s refrigerant lines and coils. First, ensure that there is a power supply to the air conditioner (AC). If the AC has access to power, disconnect it, and disassemble it to inspect any ice build-up. If there is any, wait for the ice to melt and then recheck if the fan is working. If not working, then the ice might have frozen the evaporator coils. While replacing the frozen coils, you might also have to replace the contacts of the fan belt, fan relay, or the fan motor. For excellent results, seek the help of an expert if you don’t have the skills.

Air conditioner leaking water

Prolonged water leakage might force you to replace the entire unit. To avoid the high replacement costs, switch off the air conditioner once you detect the leakage, and then work on it. The problem may result from clogged condenser drains, broken condensate pump, and rusted drain pan. So, the first action is to unblock the condenser lines using a wet or a dry vacuum. If this does not help, inspect the drain pan and the condensate pump and replace them if it has rusted. Alternatively, you can seek the services of a technician if you are not an expert.

Air conditioner vibrating

Typically, air conditioners are noisy, from the fan’s whirring sound to the compressor’s buzzing while cycling on and off. However, if vibrations accompany the sound produced by your AC unit, it may be a red alert that there are some installation errors. If you are an expert, switch off the whole unit and disassemble it to identify and correct any errors. You may also follow the installation manual if you are not familiar with that AC model.

Air conditioner not blowing fresh air

Dirty air can cause various ailments, including allergies and respiratory issues. If your AC unit is releasing air with a dusty smell, then its registers could have accumulated some foreign materials, including dust. To avoid the substantial treatment costs, ensure that you regularly vacuum the registers to prevent any build-up. Also, ensure that they are not blocked by tall objects in the room, including the furniture to allow free airflow.

Regular DIY air conditioning repairs assures you of uninterrupted long term service from the air conditioners. The repairs also save you energy costs that result from using defective AC units. However, mistakes are inevitable, and you may make some during the repair exercise. It is always advisable to call an air conditioning professional at regular intervals to do a maintenance checkup.
