Why Does My Lutron Caseta Light Flicker When Dimmed?

Device: Lutron Caseta Dimmer (PD-6WCL, PD-5ANS, ELV+)

Your lights flicker or flash when controlled by a Lutron Caseta dimmer. This can happen at any brightness level or only when dimmed low. Flickering is usually caused by incompatible LED bulbs, incorrect dimmer trim settings, or electrical wiring issues.

Why Are My Lights Flickering with Lutron Caseta Dimmer?

Device: Lutron Caseta Dimmer (Lutron PD-6WCL, PD-10NXD, RRD-6NA)

Your lights flicker, buzz, or strobe when using a Lutron Caseta dimmer. The flickering may occur at certain dim levels, when turning on, or constantly. This is usually a compatibility issue between the dimmer and your specific LED bulbs. Lutron dimmers require minimum load and compatible bulb types to function smoothly.

Why Does My Lutron Caseta Switch Have a Dim Glow When Lights Are Off

Device: Lutron Caseta Dimmer (Lutron Caseta PD-6WCL, Lutron Caseta PD-10NXD, Lutron Diva)

LED lights connected to a Lutron Caseta dimmer glow faintly or flicker when the switch is turned fully off. The ghost light is visible in dark rooms and is more pronounced with certain LED bulb brands. This happens because the Caseta dimmer draws a tiny trickle current to power its wireless radio and status LED, and that current passes through the LED bulbs rather than returning via the neutral, causing a dim glow.

Why Do My Lutron Caseta Dimmable Lights Flicker or Buzz When Dimmed

Device: Lutron Caseta Dimmer Switch (Caseta Wireless In-Wall Dimmer PD-6WCL, Caseta ELV+ Dimmer, Caseta Plug-In Lamp Dimmer)

Your lights flicker, buzz, or hum when controlled by a Lutron Caseta dimmer switch. The flickering may occur at certain dim levels, particularly at the low end, or the lights may audibly buzz when dimmed below 50 percent. Some LED bulbs may also flash when the switch is turned off.

Why Is My Lutron Caseta Dimmer Buzzing or Humming

Device: Lutron Caseta Dimmer (Lutron Caseta PD-6WCL, Lutron Caseta ELV+, Lutron Diva Smart Dimmer)

Your Lutron Caseta dimmer buzzes audibly from the switch body or the connected light bulbs hum when dimmed below full brightness. The noise increases at specific dim levels and may be more pronounced with certain bulbs. This is a load compatibility issue between the Caseta dimmer and the LED bulb's internal driver circuit — not a defective dimmer.

Why Won't My Lutron Caseta 3-Way Switch Work With My Existing Wiring?
