Our kitchen pendant started flickering three months after installation. I diagnosed and fixed it in 45 minutes without spending a dollar. Here's the exact process I used.
Step 1: Swap the Bulb
Try a different bulb first. Sometimes a specific LED fails early. A new bulb resolves the issue about 20% of the time.
Step 2: Check the Dimmer Compatibility
The kitchen pendant was on a dimmer. I checked the dimmer's compatibility list — our LED bulb wasn't on it. Replaced the dimmer with a Leviton LED-compatible model ($14). Flickering gone. This is the fix 60% of the time when a dimmer is involved.
Step 3: Check the Wire Connections
If no dimmer is involved, turn off the breaker and check every wire connection in the box. Tug each wire nut firmly — if any wire pulls out, that's your loose connection. Re-strip and reconnect. Flickering from loose connections resolves immediately and permanently.
Step 4: Check the Circuit Load
Flickering when appliances cycle on can indicate a shared circuit that's near capacity. Check which other outlets and fixtures share the circuit (flip the breaker and see what else turns off). If the circuit is overloaded, consult an electrician about adding a dedicated circuit.
If none of these resolve it, the fixture itself has a failing driver — time for a new one. Shop ceiling lights and sconces for replacements.
