SOURCE: Mini Split Heat Pump wiring

Check to make sure it is single phase, should be stamped on unit. Is this wiring coming from what use to be there?

If you replaced the old unit with this one, you can trace the wires back to the breaker box. If you are Electrically inclined or you know someone who is.
Remove the panel and trace the nuetral and ground wire to the bus termination.

Some States require or use to require that the nuetral
and ground wire be tied together. 230 is 230v ,2hot and a ground.

My guess is you tie nuetral and ground together or
I wouldnt use white wire and I would disconnect
from both ends.

If you are uneasy about electricity, talk to a certified
electrician. Contact City Electrical Inspector. Dont get hurt!

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

LG Ductless Mini Split System LAN125hv: Heat pump doesn't run.


First check your circuit breaker or fuse that supplies power to the outside unit. It's probably separate from the inside unit. Then try to turn unit on. If the fan and compressor just make a humming sound then turn it off and check the capacitor if you have a multimeter. You can also look at it and see if the top looks expanded. That's a good sign its bad, but not all bad one's look expanded. Tomorrow I will have access to an LG service manual and can let you know what the code means. Sorry I can't get it sooner. Let me know what you find.
