Caloric Gas Range RSF3400UL Timer Repair

caloric rsf3400ul freestanding gas oven: the oven will not light; the broiler works fine. The oven igniter seems to glow as brightly as the broiler igniter, but there does not appear to be any gas flow through the oven burner tube. Could the gas valve (that I understand feeds both the oven and broiler) be the problem?

Any direction on proper replacement on the glass defrost heater elements with the side-by-side refrigerator? Working within such a narrow compartment (< 14") difficut to see if the coils need to be removed completely along with the defrost assembly.

I had a problem with the fridge about a month ago where both the fridge and freezer weren't working. I used the screwdriver on the defrost clock and then it started to work. I let it run for a month and the fridge part doesn't get very cold even at the coldest setting. The freezer works just fine. I just replaced the defrost clock thinking that was the problem but the fridge still isn't getting any colder. I've just checked the back wall of the freezer and there is frost on it. Could this have been caused be my using the appliance for the last month with a faulty defrost clock? Is it possible that I caused something else to go wrong by not replacing the defrost clock right away. If I just uplug the refridgerator for awhile would that fix it?

At the lowest settings for the fresh food side and freezer side the freezer was at -5 F and the fresh food side froze everything and caused a soda can to rupture and it was still running. It sits in the attached garage near the back door to the house where it has been for 6 years and only rolled out and back to paint the wall behind it.
