Well it needs to be fix by a professional, so if you or someone you know are good at tinkering go for it. It as a sensor problem at the evaporator.

What is code 67 on a LG PTAC


Hi Jason, The link below is a web page, Click the 4th down for an LG Ductless HVAC & PTAC Error Codes manual.....
https://www.google.com.au/search?q=LG+PTAC&oq=LG+PTAC&aqs=chrome..69i57j69i61&sourceid=chrome&ie=UTF-8#q=LG+PTAC+error+codes

Code 67 ODU fan motor not rotating or proving rotation. Verify fan motor plugged in correctly & fan rotates freely. This can be a failed motor, failed board or motor could have failed and caused board failure as well. Verify 310V DC on motor wires separated by empty terminals on plug with motor plugged in, 0V DC = failed PCB, 310V DC = likely failed motor. Next step: Unplug motor and manually spin the fan (keep it spinning): on same wires you just tested, 0V DC indicates motor failed and caused board failure. 14-30V DC indicates a good motor

My amana ptac is not heating....the code "np" is displayed....how do I correct this...we just installed the unit and know little about operation. Thanks


I don't see this error code in the manual. I do see nP as an error code for Window Switch lockout. I just had this happen to me and they had me reset the control board.

Remove case, flick master switch to OFF for 10 seconds. Press Heat/Cool same time turn switch back on HOLD until off light comes on.

You should be fixed. Just had to do this for my unit. I was playing around with the settings and turned on the window switch option by accident.

Error e8


I don't see a error code E8 listed.. I take it your tried unplugging unit for at least 30 minutes then reconnecting unit. Could be a bad controller or display. If unit hasn't been serviced in a long time.. it should be checked for proper coolant levels and leaks.

You can find the service manual here...
