How do I access the bulb on the Panasonic whisperfit bathroom exhaust fan ceiling mount low profile DC pick a flow 50 80 110 CFM with LED light?

The Panasonic WhisperFit DC Pick-A-Flow fan uses a built-in LED light rather than a replaceable bulb. The grille can be gently pulled down to access the light area for cleaning, but the LED itself is not designed to be removed or replaced. If the LED fails, the unit or LED module would need to be serviced or replaced. The fan includes a 3-year warranty on parts and a 5-year warranty on the LED chip panel.
