When The Condenser Drain Is Damaged Or Defective
Another reason your air conditioner unit needs repair is when the condenser drain gets either clogged, damaged, or is defective. The condenser drain is a crucial component of the air conditioner. It helps in transporting accumulated water out of your air conditioner unit. Hence, when debris, dirt, or even algae builds up in the unit, there could be a partial or complete blockage, which results in clogging the drain and causing the air conditioner to leak. Plus, a damaged or a faulty condenser drain can also accumulate water; hence, causing a bad odor to emit from the AC, as mentioned above.
When There’s A Defective Thermostat Sensor Or System Wiring
The thermostat sensors present in air conditioners are the components within the system that is responsible for measuring the temperature of the room. It is these sensors that help the air conditioner when it comes to regulating the air’s temperature according to the control panel’s setting. Your AC’s thermostat sensor can be found close to the evaporator coils that are present inside the unit. When the air gets sucked or passed through the return vents, it passes by the coils and the sensor. Once it passes the sensor, it gets the reading of the temperature and then compares it to the reading with the thermostat’s setting. If there’s warmer air than your desired setting, then the sensor is going to activate the compressor, meaning it will start to cool the inside of your home. On the other hand, if the air that passes the sensor is the same temperature or lower on the thermostat, then it is going to shut the compressor off. This is how the thermostat sensor functions.
When a thermostat sensor is defective or there is a problem with the system wiring, it is unable to correctly and properly measure the temperature within the room. There are several signs that indicate a faulty sensor. For instance, the air conditioner does not turn off once your home reaches its set temperature. A defective sensor will cause the AC to continue blowing cold air causing the home to become extremely cold. If not fixed early, this can result in extra usage of energy, causing a high increase in the monthly utility bill. Moreover, another sign that indicates a faulty sensor is when your system continuously turns on and off and does not properly turn off once the temperature has reached its chosen settings. In this case, the air conditioner unit is going to turn off and on during random intervals.
