I have an intermittent problem. The ice maker works properly for 2 to 4 days then the ice in the bucket melts and drips down into the freezer. At the same time the freezer temp will go from -3 to +3 or 4 and the Refrig side will rise from 37 to 45 or 46. With out doing anything it corrects it self. Ambient house temp runs from 67 to 74. The ice maker is new but that did not resolve the problem. It seems like the defrost cycle may be staying on too long or the temp sensor or other sensor may not be working properly. OR? I was told by a tech that the main board needed to be replaced but he made no tests to confirm it so I didn't let him change it. It was a previous tech that said the ice maker needed to be replaced. but that didn't solve the problem. I don't think much of these fast buck artists. Perhaps you have some ideas I can try. I have a multimeter and know how to use it. Thank you for your assistance.
You will want to inspect your thermistors and also do a resistance check on them to ensure that they are not faulty. When checking thermistors for resistance you will want to check from the main board. The resistance of thermistor is as follows: at 0 degrees 42.5K ohms at 37degrees 14k ohms and at 77degrees 5k ohms. If the thermistors are out of range then the thermistor would need to be replaced.
