First I checked for continuity between the bars with both contacting a wet washcloth and the test was negative. I ordered two dryer moisture sensor bars from AppliancePartsPros.com. They arrived a couple days later and were easy to replace. The hardest part of the replacement was trying to work in the confined space inside the dryer door. Afterward, my wife was very happy because she was able to use sensor dry mode with her heavy loads and get the linens completely dry on the first run.
