How to fix Apriaire 5000 Air Cleaner when the light does not come on after 90 seconds?
- KKelly WatkinsJul 26, 2025
If the light on your Apriaire Air Cleaner doesn't illuminate after 90 seconds, check a few things. First, ensure the ON/OFF switch is in the ON position. Also, verify that the air cleaner is properly plugged in. Make sure your furnace/air handler is running by either making a heat call or turning the fan ON. It's also possible there's insufficient current to activate the Model 51 relay; in that case, wrap the blower common wire around the relay bracket more.
