Thank you for your question. I'm sorry you are having this problem with the refrigerator. The information you have received is good. If this model has a control board, it can be reset by disconnecting the power for 30 seconds and then reconnect it. If it has mechanical controls, the problem could be with the defrost timer or the thermostat. If you would like more assistance, reply to this thread and please include the complete model and serial number and I will be glad to assist you further.
