Symptoms
- Bulb base is stuck and won't unscrew
- Glass broke off, leaving the metal base in the socket
- Socket may show corrosion causing the bulb to seize
Likely causes
- CommonCorrosion or oxidation between the bulb base and socket threadsOver time, especially in humid areas, this can cause the bulb to seize in place.
- CommonThe bulb was overtightened originallyA bulb screwed in too forcefully can be hard to remove later.
- PossibleThe glass broke due to impact or age, leaving the base behindThis is common with older or very hot bulbs that are bumped.
What to do
- Turn off the switch and the breaker for that fixture, then let the bulb cool completely if it was recently on.
- For a stuck but intact bulb, try using a rubber glove or a rubber jar-opening pad for extra grip while turning gently.
- For a broken bulb with the base left in the socket, never use bare fingers to remove it.
- Press a raw potato or a piece of thick foam firmly into the broken base and turn counterclockwise to unscrew it.
- Alternatively, use needle-nose pliers, folding the tips inward against the base, and turn gently.
- Check the socket contact and threads for corrosion once the old base is out, cleaning gently if needed.
- Confirm power is still off before installing the new bulb, then restore power and test.
