From what I can gather, my refrigerator's defrost timer is not working properly. The symptom, which has occured twice now, is that the refrigerator suddenly stops cooling and warms up to ambient temperature. I have have tried cycling the temperature controls on/off and also unplugging the refrigerator and plugging it back in and it does not cool. If I leave the refrigerator unplugged for several days, then I can plug it back in and it will work properly. According to what I have been able to find on the net, this is most likely the defrost timer. The refrigerator is a Kenmore side by side apparently made by Frigidaire (model 253.51694103). The label indicates it was manufactured in April 2002.
Is there any way to test the timer to verify that it is or is not working propertly before I try replacing it? I have not been able to find a repair manual.... The part is pictured at this link (http://www.repairclinic.com/0081.asp?RccPartID ”8965) and there is no apparent way to advance the timer as on older models.
