Francis M. for Model Number msd2456deb My refrigerator has stopped making ice and there is a buzzing sound on the bottom back near the compressor. It seems also that it is not cooling like it supposed to be. Could it be the Defrost Control Board that has died and now my refrigerator is stuck on the defrost cycle ?
Answer Hi Francis. I will need you to please take the rear cover from the back of the unit off. Then see if your condenser fan motor is running. It is the fan right next to the condenser/ compressor area. If It is not running then replace it with part # 833697. The lower half section of your 2-part water valve, is the valve which supplies the water your ice maker. This part # is 61005626. Is your compressor running? The compressor start relay is part # 12002783. The defrost Control board # is 61005988. It usually fails to let your unit go into defrost and your freezer back wall will build up with frost(failed defrost). Thank you . I hope this helps. Read More...
