John R Chesterfield , MI July 24, 2015 Appliance: General Electric Refrigerator PFSS5RKZASS Ge Refrigerator Pfss5rkzass: My refrigerator stopped cooling and the lights on the front panel were flashing. How to replace Refrigerator Main Control Board Assembly. I replaced the control board myself. I was told by the repair guy that the part was $550 and would take two weeks to receive because there was a back order on this part. I ordered this part from you and had it overnighted for a total of $188 including overnight shipping. The delivery was so fast I didn't even have to empty my freezer! It only took me ten minuets to replace! This company is as good as it gets folks. Thank you! John. 23 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
