Hello, this is Ava with Think Crucial.
You may check to make sure that the power cord is correctly connected to the outlet. Test the outlet is functioning properly using another appliance or lamp. Also, check the fuse or circuit breaker. The outlet may be overloaded if other appliances are also in use. Establish and correct the cause of the overload. If none of these works, then there is something wrong with your purifier unit and contact the store where you purchase it or Honeywell for replacement. It is advised not attempt to repair the unit yourself.
You can purchase a wide variety of high-quality Honeywell replacement parts for your Honeywell air purifier direct from Think Crucial with free shipping and an exclusive 10% coupon for Fixya.com readers, use code: FIXYA10
I hope this was helpful.
