Stephen O Loganville , GA July 17, 2016 Appliance: Model WFE540H0AS 0 The oven would heat up and then it would not stay hot it would cool down Replaced the blown heating element. I also only to be on the safe side, replaced the over temp sensor. I checked it with the meter when I pulled it out and it was ok. Tested ok. Thank you very much for the less than 2 day delivery on the part. 16 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
