I did purchase a thermistor from a local parts store. I then replaced the circuit board, one light bulb and fan motor grommets. I found the on line how to videos to be very Informative and well done. Ordering process was easy. I did have one problem with the shipment that was caused by the US Postal service but, AppliancePartsPros quickly rectified the situation. I am extremely happy with the service they gave. I would surlly contact them again for any other appliance issues that I have. My refrigerator is working fine now.
