Sharp R1870 R-1870 , R- 1871 , R-1872 Microwave Operation Manual - Page 28

CLEANING AND CARE FAN The fan will automatically start when heat rises from range surface units or burners and when convection, high mix, low mix or the broil settings are used. This protects the microwave oven from excessive temperature rise. The fan will stay on until the temperature decreases. It cannot be turned off manually during this time. For other uses, select either high or low speed. PRECAUTIONS FOR PROPER USE: 1. DO NOT leave range unattended while using high temperatures. Automatic fan may start and provide excessive air to the surface units. This may cause spattering or boilover. 2. Avoid burning food. 3. Keep grease filters clean. LIGHT 1. To replace light bulbs, first disconnect power to the oven at the circuit breaker panel or by unplugging. 2. To release cover remove the screw on the light cover. (See illustration.) 3.
