Thermostat indicates 'Filter' or maintenance reminder but system operates normally

Safety: Turn OFF power to the indoor unit before removing access panels to check or replace filters.

• Inspect filter: Locate the air filter in the Ruud furnace/air handler or return grille. Remove and inspect for dirt and blockage. Replace if dirty with the correct size and type.
• Reset reminder: In the thermostat menu, navigate to filter or maintenance reminders and reset the timer after replacing the filter.
• Adjust interval: If reminders occur too frequently or not often enough, adjust the runtime or calendar interval to match your home's needs and filter type.
