Important Tips for Kitchenaid Models

  • KitchenAid offers model-specific LP conversion kits (e.g., W11453918, W11702867) that must match your unit; manufacturer instructions indicate conversion should be performed by qualified installer.

Possible Causes

How to Identify: Appliance is configured for natural gas, which has larger orifices and regulator settings unsuitable for LP; improper flame characteristics or inappropriate pressure specifications.

Part: Orifices and pressure regulator

Missing or incorrect conversion kit

How to Identify: If the oven/range lacks the proper conversion kit parts matched to model number, conversion won’t be correct; flames may be too large or unstable.

Part: Conversion orifice kit (e.g., W11453918)

Improper regulator adjustment

How to Identify: If regulator isn’t switched from NAT to LP setting, or pressure isn’t within LP water column limits, performance/safety issues occur.

Part: Gas pressure regulator
