How To Repair Your Honeywell Electronic Air Cleaner
1. First remove BOTH collector cells from your Honeywell air cleaner.
2. Put the door back on and turn on your air cleaner again.
3. Get the furnace blower running. You can do this by turning either the thermostat fan AUTO - ON switch to ON or turning the heat on and raising your thermostat set point.
The problem is with one OR both of your collector cells. If this is the case wash both of your collector cells, wait 48 hours and try it again with both collector cells. If it works now you are done.
1. Place a single cell all the way to the rear of the air cleaner and retest.
2. Now remove that cell and try it with JUST the other cell placed all the way to the rear of the air cleaner.
3. If the indicator lamp GOES OUT with one of the cells installed then that cell has a short in it.
4. Remove that faulty cell and carefully study it. Look for bent aluminum plates, broken ionizer wires or foreign objects stuck between any of the plates. Remove the foreign object, straighten the bent plate or replace the broken ionizer wire.
5. Retest that cell. If you see nothing wrong with it try shaking the cell. Sometimes a single plate will break loose from the cell. If you have a broken plate or find nothing wrong and it still shows a shorted cell, you need to replace that collector cell.
Below is a link to a diagnostic tree. Try it once you have exhausted the tests above.
To test if your Honeywell electronic air cleaner is working properly when you are done. Get the furnace blower running then slap the return (cold in winter) ductwork with the palm of your hand several times. This will loosen up some dirt in the ductwork. That dirt will enter the air cleaner and the air cleaner will temporarily begin making snapping noises. This is an indication it is working.
