I just got the same problem, and the operation light is blinking 7 times.
I had the same problem and I found it was that another unit had the heat running while I was trying to run AC on another (they're both attached to the same condenser) so it could only run heat or AC not both. Turn off the heat!
SOURCE: its not working and flashing P6. Its a Mr Slim
dear sir/madam
i think....
mr Slim A control R407c & R410a systems.
P6 = indoor coil frost protection in cooling or indoor coil overheat protection in heating.
Cooling
One of the 2 indoor coil sensors reads minus 15 deg C for 3 mins.
Heating
One of the indoor coil sensors reads over 70 deg C.
If you are sure the refrigerant charge is correct & system operation is correct then it could be a coil temperature sensor reading wrong temperature.
If you have one of those little monitor things which plug into the outdoor circuit board you can monitor the indoor coil temperature.
On later type remote controllers you can get all operating data like temp sensor data but you will need a service manual to do this.
Or you can measure the ohms resistance of the temp sensors & compare with the chart in the service manual. if you can do it by yourself do if not then contatct ot mitsubishi maintenance personnnel for furhter action,
thank you
hope answer the question
please vote!
SOURCE: Right Indicator light blinks; left is solid; nothing in manual about this pattern
that is an error code.
count how many blinks after a pause and that would be the error code.
could be 4 , 5, 7, or 9.
you could reset it by un plugging or removing power for ten minutes and try it again.
if the problem would re-occur, then there is something wrong with the unit.
as it runs, observe everything and keep me posted. see if the fn outside is running, if the filter is clean, or if the compressor is running, etc.
tnx 4 using fixya,

SOURCE: Have a Mitsubishi Mr Slim and the indicator light

Mitsubishi electric air conditioning this unit blinking light continue
What a problem
Light continue blinking
I have a Mitsubishi Mr. Slim with 3 indoor units. If one of the units is set to cool, and another to heat, the right hand operational indicator light continuously blinks at 3 second intervals. I set all my units to same mode, and the unit kicked on.
