proton Posted February 27 Posted February 27 Mitsubishi Mr slim 9000 btu 10 years old, cleaned 3 months ago. Green light flashes but thats it, compressor not coming on and no activity in the a/c unit, no air at all coming out. What is most likely, failed compressor or low refrigerant?

This indicates an error code has been detected and needs to be manually reset in order to restore normal operation. To do this, simply press and hold the power button for at least 10 seconds until the unit restarts itself. Once it’s restarted, check that all settings are still correct and that no additional errors have occurred.," Edited February 27 by freeworld 1
