    E49 Protect Stop



    Hi,

    I have a FDUMA402R Mitsubishi Heavy Industries ducted unit which shows E49 Protect Stop, it was cooling, but only slightly. no signs of any leaks that can be seen.

    Anyone know what E49 means?

    Thanks

    E49 - error low pressure or error low pressure sensor.
    In addition check LEDs outdoor PCB. At this error red LED flash 1 times and green LED flashing keeps.
