F dH says a freezer defrost ran and the sensor on the coil never climbed above 40°F, so the frost was not cleared. Sears lists the defrost fuse, the heater and the control board as the places to look. The LG-built 795 service manual gives the same failure as Er dH and adds a blocked drain and a weak heater relay to the list.

Read the model label; F dH carries this meaning on Kenmore numbers that start 795. If it comes back, it needs a visit. ### Will F dH on my Kenmore clear if I thaw the freezer by hand? A hand thaw removes the ice for a while, yet the next automatic defrost will likely fail the same way. The code says the defrost could not warm the coil, so the fuse, heater, drain and relay still need testing. ### Why does the Kenmore service manual mention 8°C for F dH when Sears says 40°F? The LG-built 795.7756x manual prints the same failure as Er dH and judges it one hour into defrost against about 46°F. Sears uses 40°F; both describe a coil that stayed too cold for the frost to clear. --- **[Read on the site: Kenmore refrigerator showing F dH](https://refrigeratorrepair.center/error-codes/kenmore-dh/)** **[Book a visit with RefrigeratorRepair.center](https://refrigeratorrepair.center/schedule/)**
