One needs to check if fans are running correctly otherwise, gauges need to be connected onto system.  assuming the condenser(radiator) is clean.

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

Hello, if the unit is blowing warm air it could be due to 1) low airflow due to dirty air filter or evapoartor coil 2) low refrigerant charge 3) compressor is not engaging. check the filter first an let me know if it is clean

Cleaned coils/cage, a/c blows better but no longer cold

It would not be a slow leak, but you don't know, if your brother punchtured the coil. If the unit is less than 5 years old, it should be still under warrenty. If it is the coil, depending on the make . say lennox heat pump. the coil is $1,700.00, Coils are all different prices. It might be cheaper to replace whole unit. SORRY

Here are coil prices

Hi I have an Amcoraire aos121hx mini split, it worked great last summer and this past winter. Haven't used it for a few months and now when I try to get cold or heat it gives a P8 error?

Check the gas pressure by depressing the Schroeder valve under the cap where the gas pipes enter the outdoor unit. you have probably lost some or all of your gas

RV AC unit won't cool, blows chuncks of ice

It's most likely an airflow problem, you say you had the vents closed? Icing up is normally caused by lack of load (air flow) or loss of refrigerant charge. Make sure all your vents are open to allow for as much airflow as possible and that your filter is clean. Some units do not work well on low airflow setting when the outdoor temps cool down at night.

No its not. Bad valves are caused by dirty filers,dirty coils that cause liquid refrigerant to slug compressor and knockout the valves. Rus

You actually posted this in the wrong area but I am originally from Minnesota and can tell you. What's happening is called ice damming. They do make a drip edge type of thing that isn't very expensive for just this very thing. Go to Lowes, Homedepot, Menards etc. NOT your local trailer supply as they usually charge more. The clerk at the hardware store should be able to help you. Good luck. Please don't forget to give me a Fixya rating.
