# LG-built Kenmore refrigerator error code F dH

### Whose code this actually is

Kenmore did not write F dH, because Kenmore has never built an appliance. This one is LG’s, and it appears on the refrigerator that LG 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 it means

A defrost heater circuit problem.

### Which Kenmore models can raise it

The Kenmore refrigerator whose model number begins 795 — the three digits before the period on the rating plate. Those digits are LG’s, which is why LG’s table is the one that applies to F dH 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: **r dH**. They are the same finding and they lead to the same place.

### What happens next

- Ice that rebuilds after every manual defrost is the symptom this code puts a name to.
- The heater, its thermostat and the control are tested as a circuit.

### Where this usually goes

The job this most often becomes is [defrost system repair](/services/defrost-system-repair/), 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 F dH, and on a Kenmore the characters plus three digits off the plate are most of the diagnosis.

### Where this meaning came from

LG’s own documentation: *LG Help Library — error code lists*. Kenmore publishes none of its own, which is why every entry on this site names the manufacturer’s document instead.
