If none of these issues are detected, call a technician and have control boards checked and replaced, if necessary. If it does not, the unit will stop. Also, improper metering may result from installation of a too short or too large cap tube. 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. 36 There may be leaks in the oil separator return line. 21. A short- and open circuit can be detected within a particular temperature range: There is a temp range, within which a short and an open are detectable: The system will not detect a sensor failure at gas-side within these temp ranges. 21: Coolant temp sensor fault. The main PCB signals an overheat and prevents compressor damage by sending out the P2 error code and stopping the system’s work. The third position is the type of fault: 1 – fuel system or air supply The animated GIF below shows an example of this: Now, when this happens, do not fret. Simply fill in the form below & you'll receive a call from our team to organise your service or repair within 24 hours Be sure they are CORRECT! Try resetting the AC: turn off the unit, disconnect it from the mains, wait for about 10 to 15 minutes, reconnect and turn it back on. Manufacturer Specific Codes P1100 Induction Control Motor Position Sensor Fault. October 20, 2015 Reply 26.1. I already checked all the wires between the two units were OK. voltage is OK also .Is there any relation ship with capacitor and the main board .THANK YOU 12.5. 12,000. Also See for Mitsubishi Electric MSZ-A09NA. Mitsubishi u3 error code The U3 code appears when there is a problem with the capacitor, unstable current or faulty varistor. 7 Day Remote controller Allowing you to program up to four settings for each day of the week, you can come home … PROBLEM WITH AC UNIT: High condensate level – drain pump failure or blockage in the drain. The valves may go faulty due to an overcharge, poorly calibrated TXV, or other factors that cause the refrigerant stagnate at the compressor. Incorrect connection may cause damage to the control board. In case of breakage, the Mitsubishi thermostat will show you different fault codes. MSZ-FH12NA. Our Mitsubishi heavy industries inverter split unit is flashing its timer light,4 times first, then 6 times then a pause then 6 times again ,what is the fault, unit not turning on the compressor. When possible we give the more commonly known OBD II component name. YES. 9-2. Piston rings in the compressor motor or on a rotary compressor and/or seals have worn out. If it is, take steps to replace it. 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. Troubleshooting for Mitsubishi air conditioners based on the results of self-diagnostics. The E9 error indicates poor communication between the indoor and outdoor units. If left untreated, it will lead to serious damage and premature death of the device. Mitsubishi Electric were very helpful and emailed the service manuals for both the indoor and outdoor units. Abnormality such as overvoltage or voltage … YES. Select a Product . 24: Vehicle speed sensor (VSS) fault. 22: Crankshaft position (CKP) sesnor fault. The signal is sent by an overload protector sensor, which is attached to the compressor. ABDULJALIL ALI May 10, 2020. Code P2 - Indication of indoor unit freezing sensor. This blinking light is actually a self-diagnosis mechanism that Mitsubishi Electric had designed that enables consumers & contractors to quickly identify a fault with its system. U6. In direct-current units, improper polarity will result in the indoor unit not working at all. The system has gotten low on refrigerant due to improper charging or a leak.
