Most parts in this unit are no longer available.

See the attachment for mode wiring.

Bake element does come on, but only when broil setting is reached, so both elements are good.[/COLOR]
This seems weird to me as in m ost units the bake element is not used when in a broil setting.

[COLOR="Blue"]Is it the selector switch or the thermostat, and how do I confirm?[/COLOR]
It may not make any difference unless you can find a supplier who still has the parts.
My guess would be the selector switch as it has to connect in the bake element during bake.
Note: that the light is just showing when the broil element is getting power.
You would have to unplug the unit and then measure the resistances of the circuit paths for the different modes as per the attached sheet.

Looks like my attachment did not get through so here is a second try at it.

Your comment that the red light means power is being supplied to the thermostat is interesting. Does the selector switch send power to the thermostat?[/COLOR]
Yes they are all part of a series circuit with the bake and broil elements wired in parallel.
The selector switch does use different contact sets depending on the setting.
Also inside the switch will be a cam so you cannot rely on a certain contact set being OK if it works in one mode does not nmean it is OK in another mode.
For instance LOWER OVEN BROIL and LOWER OVEN BAKE both use Selector Switch contacts G to 6 but they may close in one mode but not the other.
Since you turn the selector switch the contacts are close by a different part of the cam.
Hope I explained this OK.


[COLOR="Blue"]If so, why is the tstat light off thru the temp ranges but comes on when the temp dial reaches broil?[/COLOR]
This could be due to the thermostat being bad again the only reliable way is to get out your meter and check it.
Although you did not come right out and say it I somehow got the impression that the temperature switch (thermostat) did work when set to a certain temperature dependent on the mode.

If this is not the case and you never get any heat when the thermostat is set to a temperature then I revise my earlier reply and the thermostat becomes the most likely culprit.

It does sound like the thermostat. Try bake and broil with the thermostat at a temperature setting. If neither the bake or the broil element come on then I would say it is the thermostat.

At room temperature the thermostat contacts should be closed.

OK does sound like a bad thermostat but I would check it with a meter just to be sure. Unless you can find a supplier for the thermostat this may be the end of this units lifetime.
