Question about Samsung AW0593L Air Conditioner

Turns itself on and off

Energysaver is NOT on, but is keeps turning itself on and off. Even after we turn the power off, it turns itself on. The only way to keep it off seems to be unplugging it.

Re: Turns itself on and off

The unit has a timer function and a Sleep timer function. Have you ensured both of these are not on? If thy are off I would guess that either a button is bad and inducting a control signal to the controller or the controller itself is bad and just randomly is setting on and off times at random.

I have a rennai energysaver 556ftr heater, and the filter and on light keeps flashing red, i've taken out the filter and cleaned it, but still the lights are flashing. what's wrong?

If you removed the filter to clean it, while the unit was ON, that may be the problem. Turn the Master ON/OFF Switch to OFF and unplug the unit from wall outlet. Leave unplugged for 15 minutes. Remove and replace the filter. After 15 minutes has elapsed, plug the unit into the wall outlet and turn the Master ON/OFF Switch to ON. The unit should have reset itself and reverted back to the original factory default settings. In which case, you can change the settings to what you desire.

Just remember to always turn the Master ON/OFF Switch to OFF, when removing the filter to clean and replace it.

Hope this helped you solve the problem. Please let me know. Thanks.

When heater first turned on light is green then turns red

Yes this is OK. The green light is showing you that you have power. When the light goes red it means that the burner is alight.

My tank says I have 32 gallons left but the heater won't work (rinnai 556f). It turns on for about 15 seconds and the light on the power button turns red and starts blinking. What does this mean?

If you hold down the economy button and the up and down arrow buttons for 5 seconds the unit will start an error code display. Get a helper and yell out the numbers when they start blinking. Post the error codes and we can help you

Air conitioner turns on by itself

The GE Zoneline units have small DIP switches inside the unit where you can turn various functions on or off. The units have a feature called Heat Sentinel that turns the A/C on at a certain room temperature, even when the unit is turned off. It also has a Freeze Sentinel that turns the heat on automatically, even when the unit is turned off. You can turn off the heat and freeze Sentinel features with the DIP switches in the unit. There are other features you may want to turn off. Read the owner's manual and it will tell you where the switches are and which ones turn off the features. Hope this helps.
