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!

Theres a little floatation type device in the removable tank that triggers a switch just above the tank on the unit itself. Just check that that isn't stuck in the "Full Tank" position. I had the same problem and jiggled the switch to make sure it could move and my A/C was back. Hallelujah!!! Hope it works for you...
