Honeywell Ceramic Heater (HZ-370) does not swivel anymore

See if there is a little brass-looking bulb on a wire (sensing bulb) inside that can be moved away from the heat. My other thought would be maybe there is supposed to be some insulation between the control unit and the heating element that was inadvertently discarded?

Have you tried calling Honeywell? http://www.honeywellstore.com/store/products/honeywell-hz-709-oil-filled-radiator-with-electronic-controls.htm

I have never heard of a heater coming on if its unplugged?? I could say if its plugged in and the control is faulty, it could come on by itself? Can you tell me more?

If you look at the cord it should tell you what kind of wire it is....... If not most of the little heater use 16ga stranded wire rated for 105degree C at 300 volts.

most likely the thermal overload is defective and kicking off.when it resetts it will work again..it needs replaced

Thermal safety is tripping, clean it out , no repairs viable for theses units,

Not a economically viable repair.

when most ceramic room heaters stop working, the blower is clogged with lint and dust from floor use . get an air compressor, or a can of air. take unit outside using a small head philips driver remove screws while laying on an old sheet .disassemble cover carefully and blow dust away from you and clean blade without bending with a toothbrush in vinegar water not gettting any liquid on the electrical parts. reassemble. thanks karl

take a heat gun or a blow dryer and preheat thermostat and any conductive leads.
after a few pre-heats it will get the idea!

they is no reset internal the electronic circuit is deferctive some electronics parts need no be changed. i have fixed one and modify it to be more reliable.
