Parts for Ge GTH20SBBASS: Fresh Food Shelves Parts

This replacement humidity control knob lets you open and close the crisper drawer vent so you can better manage drawer moisture for produce storage. Fits on the factory control shaft and restores tactile grip for setting vent position. What it does:

• Replaces a cracked, loose, or missing humidity control knob used to open/close the crisper vent
• Restores a positive feel for adjusting drawer airflow to help retain produce freshness
• Stops slipping or stripped knob issues that prevent changing vent position
• Matches OEM fit for straightforward engagement with the control shaft

• Usually pulls straight off the control shaft; push the new knob fully onto the shaft until seated
• No special tools typically required, but use a gentle, even pull to remove the old knob
• When working inside the refrigerator, take care around sharp sheet metal and food items; disconnect power if you need to move internal assemblies
