Linda R Coconut Creek , FL May 05, 2020 Appliance: Frigidaire Washer LTF7000ES0 Frigidaire Washer Ltf7000es0: E90 code flashing on my Frigidaire washer bought in 2006. How to replace Control Board. New washers are made larger now and would not fit in the laundry room space so buying a new one was out without reconfiguring the laundry room. I looked up solutions on You Tube and found the problem, which was the main control panel. AppliancePartsPros had the part and shipped it out quickly. When the part came my husband and I followed the You Tube video to replace. It took 30 min and cost 180.00 to fix. Much better than waiting for a repairman to come, diagnose, order the part and come back when he got the part. And pay for his services. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
