Rich for Model Number Bosch side by side refrigerator Model: b22cs50sns I came home to my alarm for the freezer not working and cool not cold and took the power cord off for over 6 minutes to reset the freezer. I then checked the codes and no error codes came up. The freezer started working again due to the reset. However, every week or so it alarms again and the freezer is cool instead of cold with melting ice cream etc... Still no codes when I check after each alarm. Do you know what could cause this problem and what part should fix the issue?
Answer Rich, The information would indicate a defrost problem or possibly a control board issue. Give it a couple of days, or until the temperature starts to increase, remove the articles, and a shelf or two and check the rear wall of the freezer(evaporator cover) for frost or ice build-up on the back wall. If there's an issue, then remove the evaporator cover and test the defrost heater circuit and the temperature sensor and wiring. Test for the voltage from the control board to the heater circuit, if all checks OK. Read More... Answered by AppliancePartsPros.com | Thursday, November 7, 2019
