These little uits sometimes have a compressor overload protection device mounted on top of the compressor. It could be malfunctioning or the heat is to great in the outdoor unit.

I would clean the outdoor unit and then replace the overload switch,
hopefully that will solve your problem

I set remote on "cool"


Hi there, this is a 21/2 ton split system. You can lower it to 68 degrees, but I wouldn't go any lower then that.Auto is for the fan only, it cycles on and off in the auto position, and in the on setting it runs all the time even when the cooling stops just to circulate the air. You can try and leave it in the on not auto as this may help the room stay cooler. Please keep me posted.

PS, if the remote does not say on, and just says auto and cool, set it to auto.

New Mr. Slim system just installed. Set to "Heat." Temp setting adjustment on the remote control will not go below 59 degrees. Is that factory setting? Set at 59 it keeps room at 70 degrees,...


I have a related concern. I put the Mr. Slim unit in my garage/workshop and most of the time need it just to keep the pipes from freezing. I'd like to set it at 45 or 50 degrees, but the lowest it allows is 59. I bought this to save energy, but it's forcing me to keep the room warmer that I'd like.

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!

Most units the fan will stay on all the time,if you hit the fan button it will cycle through the speeds. The only way to turn it off is to power off the unit.

Mr slim unit in bedroom 9kbtu - room 11x12'- is humid, awful


Lets clarify. DRY mode only dehumidifes that air and does not cool. Cool is used for cooling. Dry mode doesn't normally have temp control; it is automatically set by the unit. I think 9000btu is a big unit for the room; it is overkill. I would switch to a 5000btu unit. it cannot be fixed and the BR unit needs to be uninstalled and the new unit needs to be re-installed. The price of commisioning, de-commisioning and new unit is something in which you will have to pay.
I take the time to answer your questions, so please rate me.
Thankyou

Simple matter of cleaning the unit. You have to clean the filters, the coil and around the louver.

Need to know if indoor unit fan shuts off at desired temperature


Check your operating instructions and see if indoor fan unit has an "auto" feature that allows the fan to run only when the outdoor unit is running. Allowing the indoor fan to run constantly will provide for better air circulation and less stagnation but will use more energy.

Mr.Slim Mitsubishi dual zone system


We had that problem with two units that we just had installed. Both are hooked up to one compressor. After several calls and the service person coming out twice, it turned out that they had two wires mixed up when they did the installation. Once they switched the wires the units ran ok.
BUT...now we are having another problem with the units/compressor not working after losing power in our house. We lose power on a regular basis here. Does anybody know if that means we will constantly need to call the service people to come to get the compressor working again? Or is there anything we can do to reset it? The service person that came today was not very helpful and didn't have a lot of answers for us.
Thanks
