My Whirlpool Accubake Gas Range keeps making a high pitch noise. It almost sounds like a cricket. What is causing this noise?

Some gas ranges may take 10 or so minutes to light.
Other than that you may have a defective glow bar ignitor.
If it glows and does not light the reistance in the ignitior has failed.

SOURCE: How do you unlock the oven on a freestanding

Take a wire coathanger and cut the long wire from the middle.
Bend a small "U" shape on one end.
Slide the "U" in from the left side of the oven door near the top center.
Moving the wire back and forth slowwly to grasp the lock latch.
When you feel the latch pull the wire firmly to the left to open the door.
Then have the latch mechanism repaired.

most likely you have a bad ignitor,pull out the racks and remove the floor to the stove,turn on the bake,if the ignitor glows but it takes more than 40 seconds for the flame to light you have a bad ignitor even though it glows and if it doesn't glow at all the ignitor is bad,also if the broil lights on top and the bake doesn't change out the ignitor.next time send the model number and i can look up your machine to help you better.
