Steven D for Model Number LMX25981ST Error code DH. Replaced the defrost censor with model suggested by this sight. Did a check on the heater coil and it is good. Did the test on the main board and after that the fridge worked for 3 weeks the then back to the same error code. What's going on?
Answer Steven, The Er DH error code is a poor defrost error. It is indicating that Even though it is passed 1 hour since then defrosting, if the defrosting sensor is not over 46 degrees it will cause the error. The things that can cause this would be a faulty temperature fuse, heater failure, drain that is clogged or a poor relay for the heater. With the heater already being tested and it checked good for continuity and the sensor being new, this issue would most likely be caused by a faulty control board. Read More...
