I need to install a new Bake Unit (lower heating element) in a GE wall oven model JKP07J. I thought I could just unplug the old element by pulling on it and plug in the new one, but the old element will not come out by just pulling. This oven is over 15 years old.

Most double wall ovens are technically two separate oven boxes. The lower oven box has its bake, boil elements, high limit thermostat and ofcourse its own oven sensor. If the lower oven box boil is working good and less heat on bake feature may suggest that the bake element is burned out and only getting preheated with boil element. Just a suggestion here
CHECK FOR CRACKS IN THE BAKE ELEMENT. IF THE UNIT IS NOT HEATING THE BOTTOM, BUT THE TOP IS STILL HEATING, YOU MORE THAN LIKELY HAVE TO REPLACE THE ELEMENT. THIS IS A 220 VOLT OVEN WITH 110 VOLTS ALWAYS GOING TO THIS ELEMENT, SO TURNING OF THE BREAKER IS VITAL FOR SAFETY PURPOSES. WITH AN OHM METER, UNINSTALL THE ELEMENT AND CHECK BOTH WIRE CONNECTIONS FOR OHMS. YOU SHOULD GET SOME KIND OF READING BETWEEN 10 OHMS AND 500 OHMS. IF YOU'RE NOT AT LEAST GETTING A SOLID READING, REPLACE THIS ELEMENT.
mos likely yes... but to confirm is very easy... unplug unit or turn circuit breaker off... in the oven with door open you will see the back of bake element where it goes into oven wall a couple of screws remove them and you should be able to gently pull element out...there are 2 terminals connected to element with a wire attached to each of them... first we are making sure the wire hasn't burnt off or cam edisconnected and second we can remove wires and use a volt meter and test power... set it up so you don't get electricuted and tuen oven on bake 350 do you have power coming to the wires with element diconnected from wires...if so then you have a bad element if not then a bad thermal cutooff usually located in back of unit ... good luck to you...
does the bake element come on at all? if so, try the oven out. do a bake @ 350 allow it to pre-heat, and see if once the pre-heat is comlete, id the broil shuts off. on many ovens at the beginning of the cycle during pre-heat both bake and broil elements are powered.
other than that it may be a control board, or a burnt and crossed wire in the harness.
CKD WIRING FROM PANEL OK
CKD TERMINALS AT ELEMENT HAVE 120V ON EACH ELMT
FAN COMES ON
THE ON INDICATOR SHOWS WHEN TMP &START PUSHED
MICROWAVE WORKS FINE
I ORDERED A NEW BAKE ELEMENT TO TRY-NOT HERE YET
Hi Jeff. You should have a wiring diagram with the range. Check for an envelope on the back of the range, inside the back splash, or taped to the inside side wall of the range if you remove the lower drawer. That all being said, first check to see if the start or stop time knobs on the timer have been pushed in (and possibly turned). If the clock runs, it will clear this out within 12 hours, but on these old ranges often times the clock no longer runs. Make sure these knobs are turned until they have "popped" out or you won't get the necessary voltage where you need it. Secondly, when a bake element burns out, it can cause damage to the electrical contacts in the oven selector switch (part number WB22X5122 ) which can be tested with an ohm meter if you can find the electrical diagram. Also, the oven thermostat (part number WB21X5320 ) can be damaged in the same way. Unfortunately, these parts for these old units are not very cheap.
The little bit of heat you are getting in your oven now is most likely only from the 120 volts going to the broiler element when in Bake. During Bake, your bake element should get 240 volts (until thermostat is satisfied). Setting to Broil should give 240 to the broil element.
