Janice G Marietta , GA January 11, 2015 Appliance: Model J BP80T0H2WW F2 error in ge oven oven did not heat above 300f Replaced Oven Temp Sensor even though resistance at room temperature was within normal specs. The sensor's cable insulation had burn marks (maybe from self cleaning), so I went ahead and replaced it. Oven working fine for now. 27 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
