Parts for Craftsman 917990640: Electrical Parts

Battery box tray for riding mowers and lawn tractors. Secures and supports the battery within the battery box. Replace if cracked, warped, or missing.

This EII control knob replaces a worn, cracked, or missing oven/stove control knob to restore safe, accurate selection of heat settings. It provides a like-for-like interface for turning and selecting temperature or function positions. What it does:

• Fits over the appliance's control shaft to allow manual selection of heat or function settings
• Restores a secure grip and readable pointer for accurate setting adjustment
• Helps resolve symptoms like a loose, spinning, missing, or cosmetically damaged knob
• Re-establishes positive detent feel when the original knob no longer indexes correctly

• Disconnect power to the appliance before attempting service; follow all safety guidelines
• Most knobs pull straight off the control shaft; some models use a small set screw—inspect before removing
• Align the knob's splines/pointer to the shaft and push on firmly (or tighten set screw if present)
