A missing or cracked IRC knob can take your Independent Room Control panel out of commission. This genuine Lippert replacement snaps right onto your existing shaft -- no tools, no hassle -- so you can get back to operating your room controls the way they were designed to work.
The Lippert 240523 is a direct-fit, press-on control knob sized at 3/4 inch for use with Lippert Independent Room Control (IRC) systems. IRC systems are found on a wide range of towable and motorized RVs where individual rooms or slide-out zones have dedicated control panels. Over time, plastic knobs can crack, break free from the control shaft, or simply go missing during service -- this knob restores full functionality without replacing the entire panel.
At just 0.2 lbs., the knob ships light and installs in seconds. Because it is a genuine Lippert part (UPC 848150048431), you are getting the same material and fit as the original component -- not an aftermarket approximation that may feel loose or spin freely on the shaft.
Friction-fit design presses directly onto the control shaft -- no screws, no adhesive, and no special tools required.
Sized specifically at 3/4 inch to match the IRC panel shaft diameter. Prevents the wobble and slippage that comes with wrong-sized aftermarket knobs.
Manufactured to the same spec as the original component. Part number 240523 ensures you are ordering the right knob, not a generic substitute.
Backed by Lippert's limited 1-year warranty for added peace of mind on a critical control interface.
Lippert's Independent Room Control (IRC) system allows RV occupants to manage individual zones -- such as slide-out rooms -- through dedicated control panels rather than a single central point. These panels typically feature rotary knobs and switches for lighting, temperature, or slide operation depending on the coach configuration. The 240523 knob is the operator interface that sits on the panel shaft; if it cracks or pulls off, that control point becomes non-functional until the knob is replaced.
Installation requires no tools. Align the knob bore with the control shaft and apply firm, even pressure until the knob seats fully against the panel bezel. If the knob spins freely after installation, inspect the shaft for wear or damage -- a damaged shaft may require panel service rather than just a knob replacement.
