I called a few repair places they all wanted 100.00 or better just to show up. So I looked on line and found the appliance pros they listed a part called a defrost thermostat well that's what my fridge wasn't doing the part was only 11.00 a new fridge like mine was 1100.00 so I took a chance and ordered the part. It took about 10 minutes to put it in when it arrived the next day its been working fine ever since thanks,appliance pros
