Customer Question
I have an LG...

I have an LG window unit that has a reverse cycle. It is not putting out any heat. Please advise troubleshooting ideas.

Contractor's Assistant: Did you double-check the thermostat's settings? And what about the filters?

The thermostat is fine. I will go out and check the filter. Thank you!

Contractor's Assistant: Do you plan on doing the work yourself?

Yes- that is the checking and cleaning of the filter

Contractor's Assistant: Anything else we should know to help you best?

Don't know right now- maybe later will have more questions.

If you are not experiencing extreme cold in your location then the unit may need to be repaired . Check outside to make sure the unit is not “iced up”
If it is the unit will blow cold inside until it melts the ice outside . Once the ice melts the unit will start blowing warm air .More in a moment..

This usually or can happen when the unit is operating st the “edge” of its range and the humidity is high outside.
