I pulled the defrost timer out and tripped it to the defrost mode. I waited for almost 15 minutes and opened the freezer door to see if I could hear the sizzling noice. It was not noticeable at first but after we had the door open to go to the next step we heard it. Is that do to the freezer door being open for a couple of minutes or is that a bad defrost timer? There is no noticeable ice build up in the back of the freezer.

Not quite sure why you are looking at the defrost timer.
For it to be a defrost problem the evaporator coils have to be iced/frosted up to the point that the fan cannot pull air through them. This may not be visible at the back of the freezer with the cover on.

The sizzling is probably from the defrost heater being on.
Only way to tell 100% is to remove the panel so you can see the evaporator coils and heater.

It does sound like the defrost timer needs replacing especially if the unit is now running OK.
