I have a Kenmore D42 32700 electronic air cleaner. It was purchased in October 2008. Recently the motor stopped turning the finned cylinder at the back of the unit and if you leave it on, it starts to smell like an electrical burn. I imagine the motor is stuck. What can I do to service it? I had one previous to this and it lasted about 10 years.

I would use hot melt glue to hold everything in place. The air cleaner works by charging the air particle at the front and there is high voltage on the plates. The polarity of the plate alternates where the first plate is positive, the second is negative, the third is positive, forth is negative, etc .
With first wire in front charging the dust particle, the plate attract the charged dust particle to the plate to capture it.

I hope I helped you out!

Since it's a Kenmore, you can get one from Sears Parts Central. Either online or by phone. Make sure you have your Model Number, handy.

If it was wired to the return air it will have a flag switch to let it know the blower is on, sometimes the flag comes off and it wont operate, sometimes it is wired directly to the computer board on terminals EAC that stands for electronic air cleaner and the board turns the air cleaner on when the blower is running, if you have a meter you can check voltage in both places to see which one is the problem. let me know. thanks wally

It is normal to hear occasional snapping from your Electronic Air Cleaner. This occurs when larger particles are caught by the ionizer wires. Continuous snapping is not normal however, and should be investigated as outlined below: Please note that the metal electronic cells may have some sharp edges; use care when handling the cells. Wear gloves to protect your hands from being cut if needed. Remove both electronic cells. Make sure that there is no hair, dirt, sand or any debris on the bottom inside the Electronic air cleaner. If there is, remove what you can by hand. If a lot of debris is left in bottom of the Air Cleaner, you may want to use a vacuum attachment to see if you can vacuum up what you can. Do not vacuum the Pre-filter or Post filter this may damage it. Close the access door, and then turn on the Electronic Air Cleaner and the system fan. If the snapping continues with the cells removed, contact your heating and cooling contractor for service on the unit and turn off the Electronic Air Cleaner’s power. If snapping does not continue, make sure the electronic cells are clean, dry and properly installed. Inspect the electronic cells for bent collector plates, broken wires between the plates, dirt on the insulators, and damaged collector contact tabs located on the top of the cells. Make sure the pre-filters are in good condition and are in the cabinet slot farthest from the furnace (The order of the Electronic Air Cleaner Filters are from the return duct to the furnace is: Pre-Filter, electronic cell, and then Post filter, if your Electronic Air Cleaner has one). If the snapping persists and you are unable to locate any physical cause, please contact your heating and cooling contractor for service on the unit and turn off power to the Electronic Air Cleaner.

Locate the photo electric eye that picks up the need to clean and give it a thorought cleaning. Good Luck and I hope you get it repaired. That photo cell should be your problem It's probably a little black or ruby red dot in a fin or on the housing where yhe air passes.
