I think you might have misread the model number. Is it 790.80354310 (8 not a 9 after the 790.)?

Here is the microwave schematic diagram: c.searspartsdirect.com/lis_png/PLDM/R1305065-00001.png

You are trying to remove part 061 in the above schematic. Be sure to unplug the microwave. Open the door of the microwave. I assumed you removed the two screws shown on either side of the vent grille. Try using a putty knife to remove the grille as shown in this video, which will show you how to replace the fuse: youtube.com/watch?v=C_uN6hV5FvM

I hope this helps! If that is not the correct model, double check your model number and ask the question again. If you need a professional repair, call Sears Home Services at 1-800-4-MY-HOME.

Is this happening only when the oven is on for an extended period or does this happen even when only running the oven for a short time?

Most ovens will vent from the top of the oven door. Make sure the vents are not blocked.

Since the broil works in the top oven, that would indicate that the temperature sensor is working as well. Most likely you'll need to replace the bake element.

The first thing to check is the bake element. You can remove and disconnect the bake element and test it for continuity with an Ohm meter.

NOTE: Disconnect the oven from the power source before servicing, or turn the oven breaker off.

If the bake element measures resistance, the oven control and the relay board will need to be check for voltages.

This oven has a hidden bake element. The steps in this repair guide should help you: searspartsdirect.com/diy/repair-guide/how-to-replace-a-wall-oven-hidden-bake-element

Look at the "Upper oven diagram" on the above link to see where the bake element is located (under insulation and a shield). You'll need to remove both to access the bake element.

From your manual:
1) Check that air vents are clear. See "Ensuring Proper Air Circulation" for air vent locations.
2) Get all items out at one time, keep food organized and close door as soon as possible.
3) Adding a large amount of food warms the freezer causing the freezer to run longer to cool back down.
4) Check that the temperature control is set correctly for surrounding conditions.

Clean the freezer condenser coils
Dust-covered freezer coils prevent the freezer from running efficiently and cooling properly. Unplug the freezer and clean the condenser coils using a coil brush. Vacuum up the dust. Clean the grill below the freezer door to allow proper air flow to the condenser.

If none of these apply, you could have a failed evaporator fan motor, defrost timer, condenser fan motor, or compressor. Here are all possible problems: searspartsdirect.com/diy/symptom/freestanding-freezers-repair/1234585/not-cooling/605040302

There could be several different failures preventing the bake element from heating. It could have a burnt wire connection in the bake circuit, a faulty bake element, a faulty relay board or a faulty electronic control.

The first thing to check is the bake element. You can remove and disconnect the bake element and test it for continuity with an Ohm meter.

NOTE: Disconnect the range from the power source before servicing.

If the bake element measures resistance, the oven control and the relay board will need to be check for voltages.

So, first thing is read the manual for your specific unit rather than looking at a youtube that looks close! LOL. File that under lessons learned the hard way.

So, I fixed it. I had to remove the top cover and physically pull up on the piece holding the drum. I had to pull it up while my wife told me when the screw holes lined up and then she started one. After that they all lined up and I was able to get them all screwed in. When I unscrewed the last screw the piece holding the drum fell slightly, was maybe half an inch but that was all it took to make it impossible to screw them back in. Whew!
