Paula M Kensington , MD September 13, 2016 Appliance: Model GE JBP23GS1 The timer would not quit buzzing We replaced the whole timer/clock unit. After discussing the matter with Robin on Thursday night to ensure we were doing the right thing, we ordered the part Friday afternoon, it arrived Saturday morning, and my husband installed the new timer/clock unit before I got home from lunch. Robin, thank you so much for your patience and for helping us understand what to expect. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
