PORTABLE BATTERY BACKUP POWER SUPPLY FOR MACBOOK PRO AND AIR: PORTABLE BATTERY BACKUP POWER SUPPLY ... HT201700 I need a portableback up battery for my MacBook Air 11 . ... air purifiers that controls mold.
it's possible that the ozone generator inside has gone bad. The only way to really know is to remove it from the unit and then test it with a power supply w/correct voltage of coarse. You will smell the ozone immediately if it works upon testing. (clean fresh smell) If it does need replaced, it's an easy fix for anyone with electronics knowledge. You will need to match up the numbers to get the correct replacement. Many are available on Ebay. Always disconnect the power to the unit before taking it apart. Hope this helps, Dave
With the Air 8 Models there is a number of issues from the motor to the power supply to the circuit boards. With these old units it is hard to find parts for them. as oreck no longer manufactures them. but if the parts were availible i would estimate around 100 to fix your power issue
It sounds like the main board is not getting power. The power supplies have capacitors inside that do overheat and burn out. You can test power coming from power supply leading to main board with a voltmeter. You can try to unplug for 8 hours, in meantime while unplugged, press and hold power button for 5 seconds, then wait 1/2 hour and plug back in to see if unit has reset itself
