Customer Questions and Answers for Heater Box (Heater Housing) by Whirlpool

This heater box is the protective housing that encloses and supports the heating element in your appliance. Replacing a warped or damaged housing helps restore safe, efficient heating and protects nearby components from excessive heat.

• Holds the heater element securely and maintains proper spacing from surrounding parts
• Shields adjacent wiring and components from direct heat
• Helps maintain consistent heating performance when the original housing is heat-damaged or cracked
• Common symptoms include visible melting/warping, loose element fitment, burning odors, or repeated safety shutoffs

• Disconnect power (and gas supply, if applicable) and allow the unit to cool completely before service
• Take photos of the existing layout to aid reassembly and wire routing
• Transfer the heater element and any model-specific hardware to the new housing in the same orientation
• Ensure wiring is clear of sharp edges and heat sources; reassemble and test for proper operation
