What we can confirm
Signal Demo mode, from the manufacturer's own documentation
This code has no number, because this equipment has no display to put one on. The appliance signals it instead — an alarm, a symbol or a pattern of lights — and what it means is recorded in the documentation that ships with it.

What it looks like from the kitchen
The symptom this code usually arrives with
A code names the subsystem; the symptom is what sent you to look at the display in the first place. That page says what it usually turns out to be, cheapest cause first.
-
It will not reach temperature, or takes far too long Oven not heating
Two answers cover most of these and they are cheap to tell apart. A failed bake element usually shows itself, and a temperature sensor that has drifted does not show anything at all — it simply reports the wrong number and the oven confidently holds a temperature it is not at.
- A bake element usually shows visible damage
- A sensor problem shows nothing at all
- A consistent offset is the sensor's signature

What else belongs to the ranges
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.

About Frigidaire-built Kenmore range signal Demo mode
Whose code this actually is
Kenmore did not write Demo mode, because Kenmore has never built an appliance. This one is Frigidaire's, and it appears on the range that Frigidaire built and Sears sold under the Kenmore badge. Ranges under this badge came from Frigidaire, GE and Roper, and one of those three publishes no code documentation at all — so even knowing a range is not enough. The prefix is.
What the appliance is telling you
The oven is running in demonstration mode: the panel lights and responds and the oven does not heat. It is meant for showroom floors.
This one is an indicator rather than an error. It is published in the same table as genuine problems, and treating it as one is how a working appliance gets a service call.
Which Kenmore models can raise it
The Kenmore range whose model number begins 790 — the three digits before the period on the rating plate. Those digits are Frigidaire's, which is why Frigidaire's table is the one that applies to Demo mode and no other manufacturer's does.
The other ways it may be written
The same condition is published under more than one label, because it has been carried across generations of the appliance and because a segment display draws some characters oddly: DEMO MODE. They are the same finding and they lead to the same place.
Worth trying yourself, in this order
- Follow the manual's exit procedure for demonstration mode.
- Worth ruling out before anything else on an oven that lights up perfectly and never gets hot — especially one bought as a floor model.
Where this usually goes
The job this most often becomes is oven element replacement, and that page carries a starting figure and the reasons that move it. A Kenmore range in a South Florida kitchen is usually freestanding rather than built in, which keeps the access short and means most of these end in one visit. Photograph the display before you cut the power: a reset clears Demo mode, and on a Kenmore the characters plus three digits off the plate are most of the diagnosis.
Where this meaning came from
Frigidaire's own documentation: Ranges — Error Code Guide, Frigidaire owner support. Kenmore publishes none of its own, which is why every entry on this site names the manufacturer's document instead.
