Ernie for Model Number RBS275PDB14 Our oven was not producing heat. I troubleshot the issue with a digital multi meter to the Thermal Overload Fuse was open. I ordered the replacement part. After installing I turned on the breaker, and both the Broiler and and Bake elements turned on instantly. To measure continuity of the Overload Fuse in the forums I have read two (2) different opinions of Zero Ohms and between 1K and 1,1K. Which is it as I have a device that has 0 Ohms of continuity between the terminals. Is there a second issue with my oven that I have overlooked? Please help. Thank you.
Answer Ernie, The WP9759243 Thermal fuse is a switch(basically) and should be tested for continuity, not resistance. At room temperature/below the temp. rating on the thermostat there should be a "closed" circuit. If the thermal fuse hs failed it would have an "open" circuit at room temperature. Based on your information, once you verify the thermal fuse circuit, you will need to check or replace the EOC/Clock WP8302994. With power removed and the P1 connector removed from the EOC, Check for continuity from P1pin2 black to P1pin4 red then P1pin1orange to pin p1pin2 black, on the control board connector. Both checks should indicate an "open" circuit. If there is continuity on either check the relay on the control board is "stuck" and supplying constant power to the element(s) causing the oven to overheat and the thermal fuse to open. Read More...
