Broil element does not glow at whirlpool rbs305pds16, WHAT IS THE PROBLEM?

Check the elements for continuity with a multimeter. Sometimes the connectors draw too much current and can burn out as well. Both are easy tests. A runaway temperature can make elements fail because there is no thermostatic control, they just glow bright yellow..

Either the broil element is bad or the broil relay in the clock / control is bad. Both can be checked with a meter

Understand that I am not a professional, so this answer is subject to revision by someone who is more knowledgeable.

Where I live now I'm on Natural Gas, but in the past I've had electric stove/ovens. Based on my best recall the situation you describe is NOT abnormal.

When in the Broil mode, the Bake element is NOT on, but the Broil element is on FULL-bore to provide that strong radiant heat required for the Broiling process, AND for the good browning /crusting of the product being Broiled!!!!!

On the other hand, when Baking, not broiling, IF the Broiling element were on high it would provide too much radiant heat to the top of the product being Baked, and would burn the top.

While Baking, by energizing the Broil element in a lower power setting, the Baking process is enhanced with more heat by the assistance of the Broiler element, BUT without the hazard of burning on the top!!!!!

Hope this is right and helps your understanding.

Bake and broil elements can be tested with an ohm meter for continuity. There is a relay in control / clock for both bake and broil elements. If elements test good, then those relays need to be tested for voltage.

Do a continuity test on lower bake element.

Hello there and than you for choosing Fixya
If your oven does not heat, does not heat enough or does not broil, a common cause is a burned out heating element. There are two elements, the baking element on the floor of the oven and the broiling element on the ceiling of the oven. They are about the diameter of a pencil and typically supported by metal stand-offs.
This easiest test you can do is to turn on the oven and observe the heating element. If it glows red, the element is working. When baking, the broiling element may come on to assist with preheating or to maintain the oven temperature. When set to bake, if the broiler comes on, but the baking element does not, the likely cause is a burned out baking element.
When set to broil, the broil element should glow red, but the bake element typically is not used. If the broiler does not glow, it is likely a burned out heating element.
There are other possible causes of these symptoms, refer to our diagnostic page for some other possibilities.
To test the heating element using a multimeter, follow the steps provided below.

1. Unplug the oven or turn off the power at the breaker or fuse box.
   
2. Follow the heating element back to where it goes through the wall of the oven. Remove the bracket that secures the element in place.
   
3. Unscrew or unfasten any stand-off supports that secure the element to the oven.
   
4. Pull the element part way out to expose the oven's wiring connected the element.
   
5. Label the wires and secure them in place so they do not fall back into the cavity.
   
6. Disconnect the wires from the element.
   
7. Using a multimeter set to x1, touch one probe to each of the element contacts. Expect resistance in the range of 20 to 40 ohms. Infinite or kilo-ohm resistance usually indicates a bad element and it should be replaced.
   
8. If the element tests okay, reconnect the wires, slip them back into the cavity and resecure the element.

sounds like you may have a bad bake element. try to see if the unit will get hot when set to broil. if it does then try the bake again. if you get no red hot heat from the bake element then you may need to replace it.
when an element is working properly it will heat to a red hot glow.

E1 F2 means bad connection between touch pad and control board. if connections are ok it may require parts. may get very expensive.

you most likely had a bake or broil burner short out. the unit may seem to heat but it probably doesnt bake right. look at the elements and see if they have a rough or blistered apperance to them. if so it probably isnt working. you can also check to see if both elements are glowing red when they are on.
try the broil cycle and if its ok then try the bake cycle, my guess is one of them is blown out.

What do you mean by, "properly"?
Is it heating or not at all?
Is it not hot enough, or too hot?
Upper element is for broil. It may come on briefly during bake, but usually at half power. It doesn't glow red.
Does the bottom element glow red? If not, inspect lower element, which is the bake element, for pits and rough spots. These may be signs of failure.
UNPLUG STOVE!! Remove bake element and check for continuity. If it shows open, replace. You can probably take to parts store and they can test it for you.
