Thermal Fuse WP4450249

Hello Mike, thank you for the great question. Based on our research, the blown thermal fuse may result in your oven not powering up at all or just not heating. In order to check the thermal fuse for the continuity. Set your multimeter to the ohms setting. Touch each of the two probes of the meter together. Use this reading as a baseline. Place one of each of the probes on the fuse wire terminals if the fuse is good and has continuity you should get a low ohm rating close to your baseline if the display on the meter does not change or your ohm reading as far off from that then you have a bad fuse. We hope this information helps!
