Making bleeping chirping noise all time need a circuit board
For model number LMXS30776D
Hello Diana, thank you for your inquiry. There are a few reasons refrigerators beep or chirp: Open door alarm, high temperature alarm or an error at the control board. If the control panel is not responding to your inputs, it may be related to an error regarding the control panel PS11710898 and needs to be replaced. We hope this helps.
