Safety notes

  • Before cleaning, switch off and disconnect power as the model manual directs, and let all parts cool. Stop use and tell the employer if the cord, plug, door, hinge, or door-contact surface is damaged.
  • Keep water and cleaner out of vents, controls, the turntable drive, and electrical areas. Do not use harsh, corrosive, or abrasive products.

Tips for helpers

  • Wipe fresh splashes after the oven cools so they do not harden.
  • With permission, photograph removable parts before lifting them out.
  • Use separate cloths for washing, rinsing, and drying.

Tips for employers

  • Provide the model manual, especially for grill, steam, or self-clean features.
  • Arrange professional inspection for a door that will not close, sparking marks, or damaged parts; do not ask a helper to dismantle it.
