Question about Mitsubishi Heating & Cooling

Open Question

What does it mean when the mrchi remote controller stops communicating with the transmitter for a Mitsubishi Mr. Slim, but everything else works fine? Do these controllers go out?

We have a Mitsubishi Mr. Slim split system that was installed four years ago. No problems this whole time and then a few days ago, the remote controller went rogue on us. We can't turn the a/c system off, even after replacing batteries and turning off the breaker to that unit. There are no error codes too. The only thing we've noticed is where the transmitter says connect on the inside, there's a red light, not flashing just constant.

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!
