Question about Mitsubishi Mr. Slim MXZ30TN Air Conditioner

1 Answer

Unit does not work

I have a split system 12N, installed in April 2007. I had turned off the heat with the remote two days ago. Today I cannot get any response. I have replaced the batteries, tried the reset button, turned the breaker off and on, and even pulled the fuse for the outdoor unit and replaced it. When the outdoor fuse was replaced, the outdoor unit clicked so I think the problem is in the indoor portion.

It sounds like the batteries leaked and oxidized the terminals. If you cannot get them clean enough then I would suggest getting a new reomote from the manafacturer.

Why won't my lg ductless heat pump regulate the room temperature?


After I have been reading up on your unit it appears that the thermostat is not operating correctly. I found this real basic information on installation for your unit. This link I am giving is pretty basic instal schematics. But seems to be something about your thermostat needs to be dialed in or is not working properly.

Before buying new one, try with this step. Remove batteries from your remote and reset it after 5 minutes. And also remove DC wires plugged to indoor sensor display, and after 5 minutes re set it again. Now start your unit. Sometimes it will work out. Thanks.

I had this same problem. I disconnected the thermostat wire out side at the condenser and reconnected it and it started working. A couple days later it blew the breaker again this time I found the bus where the L1, L2. GR wire connect at the condenser had melted. I wire nutted all 3 wires instead of the using the bus everything is working right again. Hope this helps.

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.

Split system outside unit won't come on for cooling, only heating


Check your filters, dog hair and lack of maintenance will definitely burden the cooling mode of the Mr Slim units.
