SOURCE: no heating from Mr slim

Go to www.mrslim.com. In the Customer Resourses file select library. Select what you want for a guide. I suggest the Operation or Technical manuals. Then select Mr. Slim Spli-ductless. Select M-series Multi-Split and the current. You will need the model number off of the outside unit to be able to pull up info on it. It may be a good idea to get the model number off of the ceiling cassette as well. Research what a P8 and E0 code is.

Typically it may mean low refrigerant or a power problem.

SOURCE: Blinking light

the light blinking is an error code. you can count the number of blinks from a brief pause. it would continue to blink the same number of blinks after a brief pause. count this blinks and you can help the incompetent person that installed your unit to diagnosed the unit from the error codes that you will give him.

if you unplug the unit, it will reset and run again. after a few minutes, the sensor would sense the trouble and turn off the unit and display this code again as a blinking light.

tnx for using fixya.

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,

Mr slim 12,000 btu 110 volt


Sounds to me like yo have dirty condenser coils (outside unit) After this runs and gets hot it loads the compressor because it can not release heat out of the condenser coil it also may have a restriction somewhere on the high side that could cause this maybe in a txv or in a line filter.

Hope this helps Ya
please rate me
