before beginning other checks.

•

fan is running.

20 minutes, the control will default from the

diagnostic mode to the normal cooling mode.

for 3 seconds.

To advance the diagnostics sequence:

To advance to the next step in the sequence, press

and hold the water filter reset button for 2 seconds or
