Sharp Air Conditioner is short cycling

If your Sharp air conditioner is short cycling, the unit may start, stop, and restart before the room reaches the set temperature. This kind of AC turns on and off quickly problem is often tied to the controls that tell the fan and compressor when to run. Start with the most likely causes: a faulty control board, main control board, or user control and display board can send the wrong voltage or commands to the system and make the air conditioner keep cycling. Before replacing a board, check the sensing components. A bad thermistor or temperature sensor can misread room temperature and cause window AC short cycling. The temperature control thermostat can also fail, shutting the compressor off too soon or restarting it before refrigerant pressure has time to equalize. Use a multimeter where applicable and compare readings to the unit’s service information. Once you identify the failed part, enter your Sharp air conditioner model number on RepairClinic.com to find the exact replacement part that fits your specific unit.

01 - Sharp Air Conditioner Control Board

The control board regulates the voltage to all of the air conditioner components. If the control board fails, the air conditioner may short cycle. Control boards are often misdiagnosed; make sure to check more commonly defective parts first before replacing the control board.

02 - Sharp Air Conditioner Main Control Board

The main control board regulates the voltage to all of the air conditioner components. If the control board fails, the air conditioner may short cycle. Control boards are often misdiagnosed; make sure to check more commonly defective parts first before replacing the main control board.

03 - Sharp Air Conditioner User Control and Display Board

The user control and display board allows the user to operate the unit by selecting fan speeds and cooling temperatures. If the board is defective, the air conditioner may short cycle. If the temperature sensor or thermistor tests appropriately with a multimeter, it's possible the user control and display board is malfunctioning and will need to be replaced.

04 - Sharp Air Conditioner Thermistor

The thermistor is a sensor connected to the control board that detects the temperature of the air. The resistance value of the thermistor changes in conjunction with the air temperature. If the air temperature rises, the resistance value will decrease. A malfunctioning thermistor may cause the air conditioner to short cycle. To determine if the thermistor is at fault, use a multimeter to test it for continuity. If the thermistor does not have continuity, or if the resistance of the thermistor does not change with a change in temperature, replace the thermistor. (To find specific temperature and resistance values, try check...ing your user’s manual.)

05 - Sharp Air Conditioner Temperature Sensor

The temperature sensor is connected to the control board and detects the temperature of the air. The resistance value of the sensor changes in conjunction with the air temperature. If the air temperature rises, the resistance value will decrease. A malfunctioning temperature sensor may cause the air conditioner to short cycle. To determine if the sensor is at fault, use a multimeter to test it for continuity. If the sensor does not have continuity, or if the resistance of the sensor does not change with a change in temperature, replace the component. (To find specific temperature and resistance values, try checking your us...er’s manual.)

06 - Sharp Air Conditioner Temperature Control Thermostat

The temperature control thermostat is a sensor which monitors the temperature of the air and activates a switch to provide power to the fan and compressor when the air temperature drops below a set point. If the thermostat isn’t working, the air conditioner may short cycle. When the thermostat shuts the compressor off there needs to be approximately a five to ten minute delay to let the refrigerant equalize before the compressor will start again. If the refrigerant has not had time to equalize the compressor may not start. If the thermostat is short cycling it will need to be replaced. To determine if the temperature contr...ol thermostat is defective, use a multimeter to test it for continuity. If the thermostat does not have continuity, replace it. (Note: Some thermostats may also control a heater and, as a result, will have three terminals. Refer to your air conditioner’s wiring diagram for more information.)
