Displaying: Er dh. Defrost heater or pcb or fuse.Bottom freezer is operational, but the refrigerator is not cooling.
For model number LRFD21855ST
Hello Louie, Thank you for the question. The DH error code indicated a Defrost issue. We suggest testing the Temperature/Defrost Sensor, PartSelect Number PS3529340 and the Defrost Heater, PartSelect Number PS12368655. They can be tested for resistance and should measure 77KO at -4°F, 60KO at 5°F, and 47.3KO at 14°F. The fuse on the sensor assembly should measure as having continuity and if it does not, then the assembly would need to be replaced. However, the defrost heater 5300JB1100Q should be tested and it should have a resistance reading. If there is not a resistance reading, then the heater has failed and would need to be replaced. We hope this helps.

Remove and replace light switch
Video makes it look easy. Kenmore refrigerator does not have "groove" along the right hand side of switch that allows for pushing down on release. Used a thin screwdriver to get under to push while holding switch edge with pliers. Kept slipping. Tape sides to avoid scratching inside of refrigerator.

Ordered a new tank assembly, but the new part also leaked because it had a hole in it. Ordered another that worked fine. Used a flat head screwdriver to remove the clips covering the screw holes to the tank assembly cover, then a phillips to remove the cover screws and the screws retaining the tank.

h the new tank (removed it by taking out the neck clip then simultaneously pushing back on the neck piece while pulling out the hose). Used this same procedure to remove the old tank at both positions. Installed the new tank, replaced the clips, pressurized/tested the system and put the cover back on. Overall less than a 5 minute job...except for the extra week waiting for a good part.
