They don't make them like they used to. I have a ceramic heater from walmart. It works well, has a thermostat on it with LCD display, I had to take it apart to service the fan and it was literally just a computer box fan... and the device doesn't have a tip over switch either... Similar heating element though.
It seemed very well made. Why didn't you try to repair it? Was the thermal fuse and thermal cut out good? Diodes are often used to measure temperature even in PC CPU's.
Yes, these parts are good, I believe the ceramics elements died in some way, they seem to read way too high, which may mean not enough current flowing, so no heat generated...
msylvain59 Don't forget, ceramic elements often have negative temperature coefficients, so the resistance drops as they get hotter, unlike metals. Fascinating design! I noticed the fan is a shaded pole reluctance motor driven one, yet it varied in speed, I wonder if there was a variable frequency drive!
***** The resistance of the elements was probably too high. Ceramic heaters are special because of the positive temperature coefficient as they get hotter the resistance increases and the current and power drop. So there supposed to be safer. The speed of shaded pole motors can be controlled with a triac based controller similar to a dimmer switch.
@@TheChipmunk2008 I was looking at the fan and noticed that also. It seems it may have a variable frewuency drive. Its kinda hard to limit speed by voltage on those as the frequency controls speed by timing poles. So could and maybe some volt/watt adjustments as well. maybe intel chip has a control for it, or possibly runs half wave 25hz-30hz for low speed and 100hz-120hz for high and normal frequency for medium if it has one
I got one want to use the heating elements for something how would I wire them
