Safe to use electrical tape on cracked microwave light socket?
Instead of the tape (or on top of the tape) add a couple of nylon cable ties. Speaking of microwave bulbs, years ago my Kenmore microwave had a burned-out small halogen bulb that was integral to a similar base as yours - no threads, just glued in. No replacement was avaiIable. I broke away the bad bulb and soldered in a standard small halogen. Has worked well for years.
