David Z Bloomington , IN June 26, 2014 F1 error code on maytag appliance runaway oven Replaced the sensor in the oven. Very easy on this and other models with this sensor-- just two screws holding it in place and a plug-n-play connector on wires leading from it. No need to call a repair service. 264 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
