Where Won't they Work
Don't ever put an LED bulb inside an oven; stick with old-fashioned incandescent "appliance bulbs" for that use. The heat from an oven will kill an LED bulb in short order. You can get LED appliance bulbs, but they're made for refrigerators and freezers and can be hard to find locally, so you may have to search for them online. An LED bulb in a fridge or freezer won't save you much money anyway because it's on for only a few seconds at a time (yes, they do actually turn off when you close the door).
LED bulbs can also interfere with remote controls that operate garage door openers. Many garage door opener manufacturers have lists of compatible LED bulbs on their website. If in doubt, choose vibration-resistant or "rough service" incandescent bulbs.
