# Frigidaire-built Kenmore refrigerator signal 77 77

### Whose code this actually is

Kenmore did not write 77 77, because Kenmore has never built an appliance. This one is Frigidaire’s, and it appears on the refrigerator that Frigidaire built and Sears sold under the Kenmore badge. Four different manufacturers built refrigerators under this badge, and several of them use an F with a number for unrelated conditions. That is the single most convincing way to reach the wrong component.

### What the appliance is telling you

Demo mode. Frigidaire's wording: designed for a display set up in a store, without using the functional components.

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 refrigerator whose model number begins 253 — 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 77 77 and no other manufacturer’s does.

### Worth trying yourself, in this order

- Follow the manual's exit procedure for demonstration mode.
- Worth checking before anything else on a refrigerator that lights up, responds and never gets cold. It costs nothing and it is a real answer on a floor-model purchase.

### Where this usually goes

The job this most often becomes is [diagnostic visit](/services/diagnostic-visit/), and that page carries a starting figure and the reasons that move it. A Kenmore refrigerator in this humidity hands its defrost circuit more work than it was sized for, and in a Miami kitchen a floor-level condenser blocks well ahead of any published interval. Photograph the display before you cut the power: a reset clears 77 77, 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: *Refrigerator Error Codes and Alarms, Frigidaire owner support*. Kenmore publishes none of its own, which is why every entry on this site names the manufacturer’s document instead.
