I have a Black and Decker BDCH100 series ceramic heater that I purchased a couple of years ago but it's been rarely used. I turned it on this winter and found that it's very noisy. According to the User Manual, the heater is permanently lubricated and there doesn't seem to be a way to add lubrication.
Are these heaters noisy by design or do I have a problem here?
Many thanks in advance.

this could have to do with the main gas feeds to the ceramic panels . they might be obstructed with a spider web or dirt,foriegn material etc. easiest fix is to take a air compresser with a blow gun tip and blow out ant foriegn material or spider webs from the gas feed pipes to the ceramic burners. the gas feed pipes have large air induction holes that a small blow gun can fit its nozzle into to blow out the gas feed pipes without having to disassemble them. that is a big time & work saver. I took my gas feed lines to the ceramic burners all apart, only to get out a spider web that i could have blown out with compressed air and saved myself 2 hours work.
anything inside the gas feed pipes to the ceramic burners will result in dark spots or the panels not staying lite, irratic burning or no burning at all. the gas needs to be able to get through unimpeded at proper flow and proper pressure for proper burning. a spider web will mess up proper gas flow. some gas, but not enough gas will get through and ceramic wont burn well and might not hold a flame.
clean out the foriegn material from the ceramic gas feed lines.
Rare posibility,if the gas behind the ceramic element escapes around the edges of the ceramic, through a bad seal of the gasket, this also will stop the ceramic from burning well.
mr heater is not made for easy diaassembly so try not to do more work than you have to.
use compressed air rather than taking mr heater all apart to clean out a gas feed pipe.
I think the warrenty on this heater is one year. If the heater housing and cord are not overheating then I would remove back panel and clean fiter and brush,vacumn,or use compressed air to clean motor and fan blades. It's possible that if you have not been using very much that it's just burning off debris and causing the smell. I hope this helps you. Thanks
mine does the same thing every year. I just clean out the dust from the vents on the back of the heater so the heater can breath otherwise it could get too hot and the safety fetcher kick in and makes the heater stop working.
There is a thermal fuse in this heater. A 133 deg. C fuse along with a bimetalic thermal cutout is attached to the top of the ceramic heater housing. This fuse is probably open, and is the most likely cause of your problem. This fuse is riveted in place, and is not easy to change.
Opening the heater case requires a special anti-tamper screwdriver. B&D don't want you inside this unit.
According to the manual, the "Caution Light" means that the unit has overheated. They suggest running on a lesser setting, but you also may want to see if you can return the unit (if it is still under warranty).
