The main PCB signals an overheat and prevents compressor damage by sending out the P2 error code and stopping the system’s work. Be sure that the outside humidity sensor and relay cable are properly connected. 31: Knock sensor fault. The cause of frostbite is a lack of gas. In alternate-current devices, failure to follow the polarity will not prevent the indoor unit from running, but there will be a communication failure between the two units. Use the Mitsubishi heat pump troubleshooting guides below. Most commonly, the head pressure at the conditioning unit or heat pump compressor motor falls due to the following factors: The 5102 error code occurs in the following cases: If the thermostat is on and when there is an open- or short circuit, the outdoor unit will restart after 3 minutes only. MSZ-GE60VA MSZ-GE71VA MSZ-GE80VA English OPERATING INSTRUCTIONS For user • To use this unit correctly and safely, be sure to read these operating in-structions before use. Mitsubishi Electric Advanced Inverter Technology provides high-speed cooling and heating with extra energy savings compared to non-inverter models. The third position is the type of fault: 1 – fuel system or air supply Mitsubishi Electric is a world-leading supplier of energy efficient equipment that will cool, heat, ventilate and control buildings. Be sure that the connector CN22 on the circuit board is not loose or damaged. The metal oxide varistor is an element, which protects the system against power surges. Check polarity before running the unit. MSZ-FH12NA. Troubleshooting for Mitsubishi air conditioners based on the results of self-diagnostics. Be sure they are CORRECT! VA series (OB447) MXZ-8A140VA1 (OC316) INDOOR UNIT No. This is not about smaller ACs or heat pumps, because they feature a capillary tube. October 20, 2015 Reply YES. 12,000. Check the humidity sensor’s (CN22) output voltage across 2P and 4P. Any Mitsubishi air conditioner has a self-diagnosis function. The E9 error indicates poor communication between the indoor and outdoor units. The modern air conditioners from Mitsubishi have a very developed self-diagnostics system, and when the control system detects an error, it blocks the operation of the entire device and displays a cause of faulty condition. In case of breakage, the Mitsubishi thermostat will show you different fault codes. Not uncommonly, the head pressure occurs due to compressor motor overheating. The metal oxide varistor is an element, which protects the system against power surges. Check the wires connecting the two units and make sure all their parts are compatible; When installing the unit, check all connections prior to powering it up. Abnormality of super heat due to low discharge temperature. OB419 REVISED EDITION-A Revision:A MSZ-GA80VA- has been added.
