Simple switch repair: Unplug fridge, pull down to remove switch assembly, slip contacts off. Reverse with replacement switch. HOWEVER, check first to see if the bulb filament might be broken, as this could cause the same symptom. OR in my case, the light socket connection was the culprit. Check that too before ordering a replacement switch.
The bulb has a plastic clear cover. That cover can just be carefully removed using a screwdriver. It's held in by a metal bracket. After you remove the cover. You'll just need to replace the bulb and then re-install the cover and bracket.
After first ordering the wrong end part, I reordered the correct part and successfully attached the handle end and handle to the refrigerator door.

Thank goodness for your company and the ability to buy parts for an old model!
