Kenmore 795 Bottom-Freezer Refrigerator Code F dS / r dS: Defrost Sensor Circuit

Medium · inspection needed

Code: F dS / r dS
Appliance: Refrigerator
Brand: Kenmore
Warranty: 30-day workmanship

What F dS / r dS means

This applies to Kenmore bottom-freezer refrigerators with 795 model numbers, which are LG-built. F dS refers to the freezer defrost sensor and r dS to the refrigerator defrost sensor. The control reports a short or a wiring problem in that sensor's circuit. Defrost timing depends on this reading, so you may notice frost, uneven temperatures or a message that returns after the display is cleared.

Common causes of F dS / r dS

Shorted defrost sensor
Damaged wiring or loose connector on the sensor leads
Control board input reading the sensor wrongly

✓ One safe check you can try

1. Check which letter appears, F or r, and write it down for us. 2. Keep doors closed as much as you can to protect the food. 3. Look at the interior vents and clear anything blocking airflow. 4. Do not remove interior panels to reach the sensor.

! Why to stop there

Whether the sensor itself is shorted or the wiring around it has been damaged
We check connectors and leads first because a pinched wire mimics a bad sensor
Part replacement is only proposed after the circuit tests point to it

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F dS / r dSF dS / r dS questions

What does the S stand for?

It marks the sensor circuit. The code says the defrost sensor reads as shorted or wired wrongly, not that the defrost heater is dead, so the first tests are on the sensor and its wires and connectors.

Will it clear itself?

It can reappear whenever the control checks the sensor again. A real short stays until it is repaired, so a message that disappears for a day and returns is still telling us the circuit has a problem.

Is this the same as F dH?

No. F dH means the sensor did not warm past 40 degrees F during defrost, while F dS is about the sensor circuit itself. They share a family of parts, but the first tests are different.
