Check for errors like blinking indoor light if present. Reset the error by disconnecting power supply from the unit for 10 sec. and "on" the unit. If the error persist, some parts of the unit may be defective and need to replace. Like room air thermistor, coil thermistor in the indoor side or the relay board. Some safety device in the outdoor may give in, some outdoor parts may be defective. You need a qualified technician for the this problem.

SOURCE: hi the outdoor unit turns

My gut says that this is evidence of a bad control board(circuit board). As usual, double check that your batteries are good in the thermostat. I have seen some weird things happen when the batteries are low. This one may be a job for your local contractor.

If you have a heat pump probably there's a wrong connectionin the thermostat, but if is not a heat pump ,the compresor is not working or the unit leaked all the refrigerant.

It's 'possible' but not likely that you need additional freon.

What is more likely is the 'filter' (for inside coil) is dirty and possibly the coil itself - and/or - the outside coil is dirty.

I would check out the filter - if dirty - I would change it and would also inspect the inside coil. If it's also dirty I would clean it the best I could (with a brush of some sort).

I would also check the outside coil and clean it if need be.

Hope this helps.

3 split units run from one compressor one is not cooling


If there is 3 indoor units from one condensing unit
(6 pipes at outdoor unit) this is classed as a multi unit

All units will run correctly as long as they all require same mode, cooling or heating, if one unit decides to heat it will shut down until master unit decides to heat then it will start, for each unit to individually heat and cool there would have to be 3 pipes to each indoor,

Heat Pump Blowing Cold


Unless you just installed or had the thermostat installed recently, I would not point at the thermostat as the problem. With what you have described I would suggest have your units serviced as it sounds like a loss of charge, or failed defrost control board. The "Aux" comes on when the unit is using secondary heating (electric heat strips). That occurs when the demand temperature (what you set it to) in Heat mode is more than the current room temperature, usually ~2-4 degrees higher. Also happens in defrost mode. Defrost is a heat pump cycle that melts any build up of ice on the condenser unit (outside unit). That process is simply the unit running in cool mode which will heat up the outside unit to melt any ice. Defrost cycles vary with manufacture but usually you can tell if is in defrost by looking at the outside unit, during defrost the unit will be warm or hot sometimes there is steam and the compressor will be running but not the fan. Defrost only happens on heat pumps in "Heat" mode. Rheem has a 10 yr compressor and parts warranty, so call the installer or Rheem authorized service company.

I have a Klimaire 16 Seer Dual Zone Mini Split Heat Pump AC and the outside unit fan/fan motor have stopped working where can I replace this at? I live near Dallas Tx surely there is something nearby?


You should check the fuses and breakers it might not be something that expensive, it could also be the controller for the outside unit that is bad. Google kllimare dealers and your zipcode.

I have a Mitsubishi heat pump that runs well but the outdoor unit does not defrost what could be the problem.


Why does my heat pump ice up in Winter?
Heat pumps naturally ice-up in the winter. It is normal for the entire coil to be covered in a white frost and even light ice, during cold weather conditions. However, it is bad for the entire unit to be encased in ice. This indicates ductless heat pump problems which should be addressed quickly to save energy and avoid serious damage to your ductless unit. These systems should periodically go into a defrost cycle. This keeps the unit running efficiently. If the coils are blocked by ice, proper heat transfer between the coil and the outside air will not occur.
How does the defrost mode work?
When the mini split heat pump goes into defrost, the reversing valve inside of the outdoor unit is energized, switching the system from heat to the air conditioning mode. The outdoor coil becomes the hot, the indoor coil becomes cold, and both - the outdoor and indoor fans shut off. This allows the outdoor coil to melt accumulated ice. When the built-in micro-computer analyzes that all ice have been melted, the heat pump heating system goes back to heating mode.
sanyo-mini-split-defrost.pngA cloud of water vapor may be seen rising over the outdoor unit and a "whoosh" sound can be heard as the refrigerant reverses direction. The entire process usually takes up to 10 minutes (depending on conditions).
How often does the system goes into defrost mode?
Ductless mini-split heat pumps have different ways of determining when to go into defrost. The built-in microcomputer determines outdoor temperature, refrigerant pressures, and several other factors. In colder temperatures the system will go into defrost more often than in warmer.
If a ductless mini split heat pump is severely iced-up in the winter it is possible that it isn't defrosting (though there could be many other causes). Let the manufacturer certified technician check your system

I keep getting a p5 error code on the indoor unit of my klimaire minisplit


I have a 3 unit split.
I found out that you can not have one unit set to warm and the other to cold. The compressor doesn't understand it.

Cycle off on and quickly re mode to Cool .
Do it to each unit and you will get it to stay on and then you can adjust.

Took a while for me but it did stay on after switching Mode at startup

No heat generated from the inside unit in Misubishi Mr. Slim


If you do not have a windbaffle installed on the outside unit the unit may never come out of defrost in low ambient temperatures. Depending on the outside temperature it might be telling the pcb to stay in defrost to keep the compressor from slugging and being damaged.

When we turn on our split AC, outside unit is not turning ON


The blinking light is because the unit is waiting for the outdoor unit to come on. If in heating mode, the indoor fan will not run before enough pressure and therefore heat has built up. You should check that the indoor air return sensor is not faulty and therefore preventing the outdoor unit from coming on.
