Greetings,
My wife uses foot baths in her shop and the heaters fail on them. The
style of foot bath she likes best is no longer available. The baths
all seem to be made by the same company, Helen of Troy. Model 61320.
Anyway, I took a couple apart to look at the heaters and they appear
to be ceramic power resistors. They are marked "20W200 ohms" , except
the ohms symbol is used. The foot baths only draw 78 watts and there
is a vibrating doodad inside too. There is a bimetal switch in series
with the resistor. The switches are inside a tube of some sort of heat
resistance woven stuff. Does it make sense that what I think are
ceramic encapsulated power resistors are exactly that? I'm thinking I
should buy a couple and see if they work. I would also like to be able
to replace the bimetal switches and the heat resistant tubing as well
but I don't know what to call the tubing.
Thanks,
Eric
