What to do if the Aprilaire Air Cleaner light flashes on and off quickly?
- MMisty ValdezAug 12, 2025
If the light on your Aprilaire Air Cleaner flashes on and off quickly, it could be due to several reasons: Over current or arcing detected, ensure components are dry. Excessive humidity - run cooling to lower humidity levels. Ensure that all 9 ionizer wires are held at both ends. Look for foreign object contacting ionizer wires or buss bar. Door not fully installed - ensure door is latched into top and bottom retainer. Insufficient current to sustain Model 51 relay, wrap blower common wire around relay bracket more. Loose connection in outlet junction box or at furnace/air handler EAC terminal, check wire nuts, screw terminals and crimped connectors for loose wires. Use only fully insulated crimped connectors.
