Whirlpool gbd307 why will The upper oven not work but the lower oven works

SOURCE: older Whirlpool RB170PBX both ovens out

We have an old Whirlpool oven, and the lower heating element is no longer heating above 250 degrees. Is this heating element something that can be pulled out -- like the stove burners can be pulled out of electrical sockets -- or is it attached to wires, requiring an electrician to replace the unit?

i have had a similar problem before and was fixed by replacing a fuse check to see if you have 2 fuses if not then the next step is to measure the resistance across coil it wont be 0ohms cos if it is your back to a blown fuse instead you should have a resistance across it i suspect you will see a open circuit meaning u need to buy a new coil for your top oven
hope this helps

I have the single oven of this style and I had to replace the thermocouple (part number 4450934) on the back of the oven three times (used the cleaning cycle three times). After using the cleaning cycle, the oven would not heat so each time I had to pull the oven out from the wall to access the back so I could change the part. Once a new part was put on the back of the oven, it worked fine. To pull the oven out, open the oven door and look down by the doors hinges. On each side you will see a screw that's holding the side molding on. Remove the screws and then the molding. That will give you access to the screws that hold the oven into the framing around the oven. Remove the screws and then you can pull the oven out to access the back to change the thermocouple. The oven is heavy so you may want some help to get out. It is not a one man job, maybe a one man and wife job. It is heavy. I hope this helps. Better late than never.

this could be the timer is set to auto this data sheet might help For all Free appliance repair videos visit our VIDEO TUTORIALS 1, If the fan motor in the back of the oven is going round and the temperature light is on (normally little red light), but there is no heat then you will probably need a new oven element, these are generally very easy to fit and readily available from our website these can be tested with a electric meter.
To gain access to the element you will have to remove the back plate from inside the oven. Once removed you will see the fan and element, if you look closely at the element you will probably see a small hole burnt in it where it has blown. Sometimes however there is no evidence of a fault but the element is open circuit ie: broken inside the element casing, either way it will need replacing. Some elements will are fixed from inside the oven and some are held in place by nuts from the rear of the machine.
2, If your fan oven is getting warm but takes a very long time to cook or is burning the food more on one side than the other, then you need to check if your oven fan motor is working you will see the blade turning fast if it is ok. if the element is heating but the fan motor is not blowing the heat into the oven then you need To replace the oven fan motor is a little more expensive and a bit more involved.
3. If you have the opposite problem ie: your oven is over heating and burning everything then you will need to replace your oven thermostat
4, A quite common and easily overlooked answer is if your oven is not working at all ie: no heat and no fan then the chances are that someone has put the oven timer into AUTO mode, simply put oven back to MANUAL mode and all should be working again.
