The SV21722 is a range hood rotary switch used to control fan speed and light functions on select range hoods. The rotary switch mounts to the control panel and allows the user to select between fan speed settings and toggle the hood light. When the switch fails, the fan may run at only one speed, stop responding to input, or the light may not turn on or off. This is a direct OEM replacement for the SV21722 position on the range hood control panel.
