Jay G Columbia , SC July 19, 2014 Appliance: Jenn-Air Freestanding-Double Oven-Dual Fuel JDR8895AAS Jenn-Air Range Jdr8895aas: Oven acting erratically flashing bake indication shut down during cooking checked control panel diagnostics per service sheet in back of oven code indicated sensor open circuit detected. How to replace Oven Temperature Sensor. I replaced the sensor. Turn off power, be sure oven is cold Remove oven door (put in broil position, pull straight up, set door aside, carefully release tension on arms and gently park them against the door frame - do not let them smack into the steel or it will crack the ceramic coating) Remove oven rack Remove 2 screws holding sensor to back of oven cavity wall Gently pull leads forward to find connector, it is supposed to be able to be pulled out from the front. However, my connector got stuck in the opening, so I had to remove the back of oven to free it up Put down cardboard to protect floor Slide out oven Remove screws holding rear cover plate on Find sensor connector buried in the insulation, disconnect sensor from harness connector Ease sensor connector out of hole into oven cavity Put new sensor lead in hole from inside the oven cavity, thread into space in back of oven Secure sensor bracket to oven wall Plug in sensor connector to harness Replace rear cover, reinstall screws Push oven back into position Put door back on Put rack back in Restore power to oven I was able to confirm it fixed the problem by using the temperature probe on my multi meter Set the oven to 350 and let it preheat. When it beeps,open the door and insert the probe in the center of the oven, making sure it does not touch the rack. Close the door and do not open it again. Let the oven run for 15 minutes at 350 degrees. My meter does a min/max/average function and it averaged out to 348 degrees over 15 minutes. Note the instantaneous oven temperature will go up to 50 degrees above and below the set point as part of the cycling of the heater element. This is perfectly normal, you are looking for the average temperature over the length of time you are cooking something. 8 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
