If the nonvolatile memory data of your Mitsubishi Electric Air Conditioner cannot be read properly, replace the inverter P.C. board.
What to do if temperatures of P.C. board temperature thermistor or compressor exceeds limits in Mitsubishi Electric SUZ-KA09NA2.MX Air Conditioner?
If the temperature of the P.C. board temperature thermistor exceeds 72 to 85°C, it may cause the temperature of the P.C. board temperature thermistor or compressor to exceed limits. In this case, you should check the outdoor fan motor of your Mitsubishi Electric Air Conditioner.
What to do if discharge temperature thermistor exceeds temperature limits in Mitsubishi Electric Air Conditioner?
If the discharge temperature thermistor exceeds 116°C, the compressor will stop, causing the discharge temperature thermistor to exceed temperature limits. To resolve this, check the LEV (Linear Expansion Valve) in your Mitsubishi Electric Air Conditioner.
What to do if temperature of fin temperature thermistor exceeds limits in Mitsubishi Electric SUZ-KA09NA2.MX?
If the temperature of the fin temperature thermistor on the heat sink exceeds the threshold, it can cause the temperature of fin temperature thermistor to exceed limits. To solve this, check the outdoor unit of your Mitsubishi Electric Air Conditioner.
What to do if there is overcurrent protection interruption in Mitsubishi Electric SUZ-KA09NA2.MX Air Conditioner?
If large current flows into intelligent power module, it can cause overcurrent protection interruption. To address this, check the compressor of your Mitsubishi Electric Air Conditioner.
Why Mitsubishi Electric Air Conditioner outdoor unit does not operate?
If the outdoor unit of your Mitsubishi Electric Air Conditioner does not operate, it might be due to the overcurrent protection cut-out operating 3 consecutive times within 1 minute after the compressor starts. In this case, you should check the outdoor thermistors.
What to do if air trapped in the refrigerant circuit are detected in Mitsubishi Electric SUZ-KA09NA2.MX Air Conditioner?
If air trapped in the refrigerant circuit are detected based on the temperature sensed by the indoor and outdoor thermistors and the current of the compressor, check of outdoor refrigerant circuit of your Mitsubishi Electric Air Conditioner.
What to do if DC voltage of inverter cannot be detected normally in Mitsubishi Electric SUZ-KA09NA2.MX?
If the DC voltage of inverter cannot be detected normally in your Mitsubishi Electric Air Conditioner, check the inverter.
