How to fix? GE wall oven (single, self clean) model JKP13G0P4BG (or JKP13GP4BG), (21 years old). Baking element: not heating, not baking. Broil element/broil function working fine. GE wall oven (single, self clean) model JKP13G0P4BG (or JKP13GP4BG), (21 years old). Baking element: not heating, not baking.Broil element/broil function working fine.Display and control panel including touch pad seem to work fine. 1. Removed old baking element. The sheath looks good but one of the element lead connectors was black, and a 2mm – 3mm portion of the pink solid electric insulation on the baking element lead (at the end of the sheath and inside the sheath) between the sheath and the coil wire was damaged, (2-3mm portion of that solid insulation crumbled from heat (?) and missing). I measured continuity and the resistance of the old baking element and it indicated continuous and 29 ohm resistance, which is normal at ~ room temperature. Due to the damaged short portion of the solid electric insulation on the old baking element, I replaced the old baking element with a new one. The new baking element measures 29 ohms (normal) as well. 2. The electric wire leads from the back of the oven to the baking element look black with some damage to the wire insulation. The wires are/seem continuous. I cut a 2 inch portion of black damaged wire at the end of one of these wire leads and connected a new wire portion of high temp insulated 14 gauge wire (with a new connector to the baking element) using a ceramic porcelain hi temp wire nut. I expect that the damaged wire may suggest some electrical problem in the oven. It is 21 years old. 3. Removed and tested the resistance of the temperature probe at the back upper left corner of the oven cavity. Temperature probe measures 1106 ohms (normal at ~room temp). Reinstalled the temperature probe. 4. With the new baking element and the repaired wire lead to that element installed, I tried to start and use the bake function: 1) I Push the bake button on the keypad, the word “bake” is flashing on the display in red letters, 2) I adjust set temperature up to 300F, 3) display still shows the word “bake” still flashing on the display in red letters (for about 5 seconds), 4) After 5 seconds, the temperature indication on the display changes to 100F, and at the same time the word “bake” stops flashing and remains solid “bake”, and the word “ON” appears and is solid, 5) after 2 additional seconds I can hear a very quiet sound of “clicking” or switching (?) as if some protective feature is activated (???), 6) The baking element does not heat up at all. As indicated above, the broil function is fine and works well. 5. Measured voltages with the oven bake off, and also with the oven bake function being started (as described in item 4. above and later with the oven bake “ON” but not heating, and indicating 100F  .1) Voltage between the two bake element wire leads is 0 volts (should be 240volts) throughout the sequence.2) Voltage between one of the bake element wire leads and ground (ground in oven body drilled screw hole): 120 volts throughout the sequence and also with oven/bake off.3) Voltage between the second/other bake element wire leads and ground (oven body screw hole): 0 volts throughout the sequence and also with oven/bake off. Any advise? Comments? Diagnosis? Thank you
