Trying to replace main oven bulb: cover jammed

when you go to the service agent to get the correct bulbs ( (need to be pyrex glass ones as normal bulbs will not stand the oven heat) ,ask them how to remove
the fat from cooking gets in the glass threads and then goes to carbon , making it very hard to turn the covers
maybe a oven cleaner sprayed around the glass may help release the threads

In most ovens, move the metal bracket to one side. the glass dome cover should fall out. Unscrew the old bulb. Screw in the new bulb. Place the glass dome cover back over the bulb. Move the metal bracket to hold on the glass dome cover. Easy job to do.

On my older Jenair, it is on the upper surface of the oven. It has a glass cover that would need to be removed to access the bulb.
Could be the switch or connections at the switch that is preventing the bulb from operating. Depending on age of oven and frequency of use of the light, oven bulbs last a long time. Mine is still good after 26 years!

2. If necessary:

Replace bulb with a 40 watt, 230 V, 300 °C heat-resistant

Which model Whirlpool range do you have? For most Whirlpool ranges that I have used , the oven light is covered by a screw-on glass cover. When the oven is cool, unplug the range, open the door and turn the cover counter-clockwise (to the left). Then remove the 40W bulb (again counter-clockwise rotation). Replace the bulb with another 40W appliance bulb. Then replace the cover by turning it clockwise until it is tight. Do not over-tighten either the bulb or the cover. Then plug in the power cord for the range. (Unplugging the unit makes sure that you will not get shocked if anything goes wrong. Sometimes the bulb may break in the socket - in that case, use pliers to unscrew the base of the bulb before replacing it with a new bulb.)

Whirlpool has the manuals for most of their appliances on their support site: https://www.whirlpool.com/webapp/wcs/stores/servlet/OCManualsLiteratureSearchView?catalogId=10561&langId=-1&storeId=10211&krypto=5QgxQhneFliXuEuX564wSQ%3D%3D&ddkey=http:OCManualsLiteratureSearchView .

I hope this helps.

The glass cover over the bulb should screw off, remove the bulb and replace it with a new one of the correct type. Clean and replace the glass cover. Be careful not to use force which could break the glass and cause an injury. Make sure that the stove main switch is off. (The lamp cover may have a screw type or have a bayonet fitting).

Having tried several ways to get the glass cover off, there is one other thing you can try.
Spray some WD40 around the glass cover,and keep trying to tighten and then unscrewng it, and tighten again.
If this does not work, then the last resort is to break the glass cover, which is what I have had to do in the past,. but make sure you can get a replacement cover first.
Please rate my solution.
Thanks.

Pry back the bulb glass cover wire spring and remove glass cover. Use heavy rubber gloves or a plastic bottle opener(piece of serrated soft plastic/rubber) and unscrew counterclockwise.
