Lg minisplit heat pump will not heat

I purchased an lg minisplit heat pump system over the summer and installed it in August and it cooled great. When it was put into the heat mode, it was blowing cold air. I found the reversing valve not energizing. I replaced the board on the outdoor unit. Now when the system is put into the heat mode, you can hear the reversing valve energize but nothing else happens except the indoor blower comes on and runs for about 10 seconds. I cannot find any technical manuals or any place to get help.

You may want to check that the pressure switch is not functioning? Secondly there is also a thermo sensor on the condenser coil which could be faulty.

Our AC has had a lot of trouble over this summer and we recently had an issue just like yours. We ended up calling an air conditioning repair technician and had it resolved.

I have a LG minisplit (indoor unit LSN122HE /outdoor unit is LSU122HE) it cools great dehumidifies also and has for 3 months of summer. However its cold now and it will not heat. It runs for a min out


That's an inverter series motors... the outdoor fan motor is on an ambient controller to maintain pressures when cold outside in air conditioning mode, but not in heat...only defrost when needed. Check the settings on the outdoor board for defrost timing

Whirlpool mini split


Peek inside the opening on the front of the inside unit. You should be able to see the blower assembly/fan blades. See if any of them blades are cracked, warped, or debris on them. If seen these minisplits mildew on those blades also, which will cause it to be off balance. If you move the fan to different speeds does the sound change? If its down that since day 1, its probably a defect. Hope this helps!

SOLEUS KFHHP-22 - Heater doesn't blow air at all, warm or cold. Cooling works great but no heat.


Doesn't matter how hot it was when installed, there still should have been proper start up performed. That means running unit thru all cycles and checking charge. If it was installed this summer then installer should warranty service to return and complete install properly.

Hello, I purchase an LG dual split minisplit air conditioner. It worked all summer long but now both wall units display a "CH 46" error and do not turn on. Any idea what the problem is and how...


A CH46 error indicates the low side sensor or suction line sensor is defective and not within acceptable parameters. It may be loose or off or simply bad.

We gave a Goodmn Hertz 60 Phase I heat pump - installed this summer....worked great for cooling..now that temps are dropping we are needing heat. When we turn it on it comes on but never heats. Think it...


If you changed the unit but didn't change the thermostat it is possible that the thermostat that you have will not work with that unit. I see that the unit you installed is a heat pump, you may have a straight cool T-Stat. If you put the T-Stat in the "Auto" "Heat" mode the outdoor fan and the compressor should be workng as well as the blower fan. If it turns out that the outdoor fan and compressor are not running you will want to buy a Thernostat that is compatable with heatpumps should be 2 heat/ 1 cool

Blowing out warm air


Turn thermostat switch to 'cool' setting. It's a 'heat pump' and is in the heat mode.

Ductless minisplit in old mobile home


ductless mini split units are a very good choice!  they are obviously quieter, more efficient and easier to maintain than window units. the downside is the initial expense of buying the unit, but this is paid back in eletric savings and peace of mind. Good luck Peyton
