It works for a about a minute and then the light blinking begins and it shuts off? What would be the most likely problem?

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.

Operating indicator light is flashing on Mr.Slim A/C


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!

Same problem here... Blinking green light. Purchased new battery and is still doing the same thing. Very disappointed-these cameras are not cheap. :(

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.
