Marcia for Model Number JBP72DM2BB My oven wont heat it showing f4. Can you tell me what is wrong with it?
Answer Hello Marcia. Usually the F4 is for a bad oven sensor on the unit. You will need to test the sensor and if it is good, you will need to replace the control board. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
