Hello,

Have the typical electric kitchen Range; Whirlpool model of a few years
in age.

Questions:

- Is 220 V (or 110 ?) applied directly to the top elements
via the rheostat ?

- With the Rheostat turned on Full, Max. Hot, is a full 220 V being
applied across the heating element ?

- There is no transformer used. True ?

Thanks,
Bob

There is always 220 applied, then switched on/off.

True but they're not rheostats, either, they're generally just a
calibrated bi-metal strip-controlled set of contacts to provide a
time-modulated on-off cycle; longer on, higher temp.

I don't know if any of the newer ones have gone to solid-state controls
or not.

Tere's a good diagram of the guts of one here...

-The second fire? I cannot see if it was the coffee maker or the electric
grill that was at fault. ww-

Hadn't looked at the forensics; had just found the pictures/diagram of
the control switch some time in the past during another discussion so
this recalled the site and a quick search found the link...

OK, so on looking--AFAICT he doesn't actually fully commit to the root
cause but does indicate the one stove burner was found in "ON" position
which would likely indicate it was forgotten and left on. I'd guess the
coffeepot is incidental collateral damage. Given the final statement is
that the right front burner was on that while not stated explicitly that
is the conclusion to be drawn.

They are not controlled with a rheostat.
They are just switched on and off.
At high, permanently on.
As you turn it down, it cycles on and off.
The lower you turn it, the more time it is off.

Some expensive ranges have electronic devices these days.
But no rheostats.
Never have been.

In days of yore, there were multiple elements connected in series and
parallel witha special switch.to get various heat outputs.

Hello,

Just a quick thanks for all the replies and info.
Much appreciated.

Diagram was great; just what I was looking for.

Had no idea they worked this way; quite clever.

Regards,
Bob
