According to About.com, if your air conditioner keeps blowing fuses or tripping circuit breakers, it is because the appliance is trying to draw more current than the fuse or breaker will allow. This can result from a window-mounted air conditioner being plugged into a circuit that is insufficient for its needs, or it could indicate that the air conditioner needs servicing.Know More
Circuit breakers and fuses are rated for a certain number of amperes. If the current goes above the rated amperes for more than a few seconds, the mechanism breaks the circuit. This is to prevent the excess heating that overcurrent can cause in the wiring and ultimately prevents fires. If an air conditioner's circuit is simply not powerful enough for its needs, the fuse blows every time the unit is started.
When an air conditioner begins blowing fuses while connected to a properly rated circuit, it could indicate a problem with the compressor. If the compressor has difficulty starting up, it can increase the amount of amperes the unit attempts to draw, overpowering the circuit and blowing the fuse. In any case, blown fuses should not be ignored. The unit should be checked by a professional to prevent a possible electrical fire.Learn more about Appliances
During the warmer months, the thermostat to an air conditioner should be set at 78 degrees Fahrenheit. If this is not comfortable, some experts recommend lowering the temperature to no less than 74 degrees to avoid high utility costs.Full Answer >
A car fuse breaks, or "blows," when its amperage rating has been exceeded. Repeated breaks may indicate that the replacement fuses do not have the proper rating or that the fuse is connected to an overloaded circuit.Full Answer >
Blocked condensation drain lines often cause excessive amounts of water in an air conditioner drain pan. These lines are designed to funnel excess water from condensation away from the air conditioning system inside the home. If these lines become blocked, the excess water drains into a drain pan.Full Answer >
To troubleshoot an air conditioner thermostat, identify the type of thermostat that is in use, check that the unit is receiving power and ensure the unit is installed properly. Most thermostats are either electromechanical or electronic, which affect how the room's temperature is determined.Full Answer >
