My 4 yr old Kenmmore Gas range started acting weird yesterday.

Set it and it would come up to temperature-- but wouldn't maintain the
temp-- it essentially just went off, though the indicator light stayed
lit.

I cooked a roast by turning it off and back on every 15 minutes or so
for a couple hours.

I ordered a $30 temperature sensor from repairclinic.com. It will be
here Wed--

Just wondering if anyone has any other thoughts in the meantime.

Thanks
Jim
