Re: model number

Visit Mr. Slims website at There you will find a tab for Customer Service. Look in Library to find your model and technical manual. You may have to look at a few to find out what you have for an inside unit, probably it is a PUG.

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.

One of the 2 indoor coil sensors reads minus 15 deg C for 3 mins.
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!

How do you change the air filter for the Mitsubishi Electric Mr. Slim, Model #msh12tn and where can you buy them?

If this is a ceiling mount, there should be to slide tabs on front of the
unit, slide those back and the cover should come down, it has a couple of safety chaines to keep the cover from coming all the way down

I need to clean the blower part of my Mr. Slim ( the cylinder )

mr slim has this cover. just unscrew the whole cover and you've got the visible blower. the power supply must be turned off so there is no electic shock or accident that other person may turn the a/c. then there is this cover of the fan with a lock so unlock it and you can clean it throughly with a cloth.....

No cool air

it is quite posible the unit is short of gas. this could make part of the indoor coil colder than the rest.
