Tyler Z.: Home Appliance Technician: Good morning.
Tyler Z.: Home Appliance Technician: Do you have a full model number located on a sticker around the front frame of the oven and seen if you open the door or remove the drawer/panel below the door so I can better assist you?
JustAnswer Customer: The model number is LRE304535B-01
Tyler Z.: Home Appliance Technician: OK perfect.
Tyler Z.: Home Appliance Technician: So this is an electric oven.
Tyler Z.: Home Appliance Technician: F7 means that the oven isn't heating which is accurate since it won't heat on bake.
Tyler Z.: Home Appliance Technician: You know the oven is getting 220 volts because it works on convection bake.
Tyler Z.: Home Appliance Technician: Convection bake uses a different element than traditional bake.
Tyler Z.: Home Appliance Technician: That means your bake element below the floor has either failed, or the relay on your main control board has failed and isn't sending power to the bake element anymore.
Tyler Z.: Home Appliance Technician: You'll need to pull the oven out, unplug the oven, and remove all the screws going into the back sheet metal panel.
Tyler Z.: Home Appliance Technician: Remove this panel and then locate the wires going to the bake element.
Tyler Z.: Home Appliance Technician: Unplug the bake element (again it's below the floor inside the oven) and test continuity through the element with a multimeter.
Tyler Z.: Home Appliance Technician: If it doesn't have continuity, replace the element.
Tyler Z.: Home Appliance Technician: If it does have continuity, you need a new relay control board.
Tyler Z.: Home Appliance Technician: We are on the honor system here.
Tyler Z.: Home Appliance Technician: If you need anything else, just let me know.
Tyler Z.: Home Appliance Technician: You can continue asking follow-up questions at no additional charge after rating my service if you still need assistance.
JustAnswer Customer: The oven is working on conventional bake, just not working when trying to use convection bake
Tyler Z.: Home Appliance Technician: I understand that.
Tyler Z.: Home Appliance Technician: I believe I even stated that in my answer.
