Timothy B Cardington , OH April 05, 2016 Appliance: Model GE JBP76G V1 Whenever we tried to turn on our oven or broiler nothing would happen except the preheat light would flash after checking the user manual the flashing light indicated a possible sensor problem We checked the resistance of the sensor and it indicated it was defective. We ordered the part before 2:00 pm and it arrived the next day around 1:00 pm. It took about 15 minutes to change and we were up and running. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
