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

Now that you've included that it's a gas range, that brings
up a whole new batch of possible issues. If it's coming up
the the correct temp and then shutting off, the temp sensor
is ok. Is this a pilot type or intermittent ignition type
of oven? Your issue here would seem to be in getting the
burner reignited when the temp has dropped by the
hysteresis amount.

Our oven has both an igniter and once lit, a pilot light. The pilot light
insures that it will re-ignite the flame when it goes to a low setting. Also
there is an "eye" like in a furnace, to tell if there is flame there. On
others it's just a heat sensor; hot, it's OK; not hot, it shuts fire off.

Any help?
