The entire owners manual that probably got tossed out with the box or put in a drawer and is now long forgotten is available online as a downloadable .pdf document. GE makes 2 air purifiers: PERMAtech™ ionizing air purifier and the Hepa Air Purifier. Both of these are sold by Walmart. I pasted the filter cleaning instructions here for the first PERMAtech model. See the second link for the second model. PERMAtech™ FILTER CLEANING INSTRUCTIONS 1. Filter Service Indicator ( ) – Your air purifier has an indicator light that illuminates when it is time to clean the PERMAtech™ filters. 2. Every few weeks, check the condition of the filters. 3. Turn off and unplug unit. Remove the air inlet grill by pulling the air inlet grill towards you by grasping the finger tabs on both sides. 4. Remove and examine the foam prefilter. If it has collected a noticeable amount of dust or lint, remove it from the inlet of the grill and wash it in warm soapy water. Rinse and drip dry the pre-filter thoroughly before replacing it into the inlet of the grill. 5. With the rear grill removed, check the condition of your PERMAtech™ filters. If the filters are dirty, remove them by gripping on both sides and pulling forward. 6. To clean the PERMAtech™ filter use a crevice tool or brush attachment with your vacuum cleaner. Run the attachment along the inlet and outlet side of the filter trying to clean between the pleated filter layers. (Figure 1). DO NOT USE WATER OR ANY OTHER HOUSEHOLD CLEANERS OR DETERGENTS TO CLEAN THE PERMATECH™ FILTER. 7. This model utilizes a hang tab and filter clips to insure that the filter is properly in place. Before replacing the PERMAtech™ filter make sure the hang tab is securely in place. The clip can only be attached to the tabs on the filter one way. The filter clip should easily slide onto the filter hang tab with only a small amount of pressure. DO NOT use force while attaching the clip to the filter. (Figure 2). 8. Align the clip on the top of the PERMAtech™ filter with the rails on the inside of the purifier unit. Gently slide the filter onto the rail (Figure 3). NOTE: The side with the soft gasket should face inward. 9. Replace air inlet grill back onto unit securely. 10.The filter service indicator must be reset once the PERMAtech™ filters have been cleaned. Reset indicator by pressing the power button ( ) on the control panel for 2 seconds. Filter Life – The filter has been designed to never need replacement, however, it does need servicing. We recommend that under normal conditions of continuous use, the filters should be cleaned at least every 3 months to help maintain optimal performance. Should the filter become damaged during cleaning replacements are available by calling 1-877-207-0923

You may need to take it out and re-install it. You might also try tapping on the light to see if that helps. It is usually a contact issue.
