Did you find an answer to your orange light question? I have an AM4000 defender that I bought off Craigslist and thought I got a good deal on it. One minute after turning it on the red light came on. I tried to reset it but  the red light won't flash so you can't reset it. I don't know if it's a filter problem or a circuit board problem and I don't want to spend $100 bucks on filters to find out it's a different problem. If you buy filters on e-bay, they're cheaper but if you spend $100 from a distributor then you reactivate the warranty. I'm sorry I bought it.

I'm going to go out on a limb and guess you want the Defender model and not the Majestic model. I believe the latter is a vacuum. Here's a link to the Defender 360 manual. Best of luck.

Schedule: Remember, to receive the full benefit from your Defender® , replace your filters regularly. • Every 6 months, replace your Enviropure® Charcoal Filter. • Once a year (for Perpetual Warranty*)/up to every 3 years (depending on usage), replace your Medi-Filter® Cartridge.

The light is a reminder to change the filter, it does not sense if the filter has been changed or not.
When the red light is blinking, press and hold both up and down arrows until the red light blinks RAPIDLY, release both for a second or two, and press and hold both again until it stops blinking.

I found that the buzzing can be removed by blowing out the unit, cleaning the blades and taking a long cotton swab and alcohol to thoroughly clean the corona wire - carefully - don't break it. The wire should be clean enough that the slider/wiper runs smoothly up and down the wire after cleaning. If it drags or is rough to slide, you will still have noise no matter how many times you clean the blades. The wire gets a "crust" on it.

You probably have a burned out high voltage transformer. That's what produces the ozone. Helpful hint...........the high voltage transformer is also the one used in bug zappers
