Microwave Oven Care

General Cleaning

IMPORTANT: Before cleaning, make sure all controls are off and the microwave oven is cool. Always follow label instructions on cleaning products.

To avoid damage to the microwave oven caused by arcing due to soil buildup, keep cavity, microwave inlet cover, cooking rack supports, and area where the door touches the frame clean.

Clean with mild soap, water and a soft cloth or sponge, or as indicated below.

■Nonstick cavity coating (on some models): To avoid damage to the microwave oven cavity, do not use metal or sharp utensils or scrapers, or any type of abrasive cleanser or scrubbers.

■Grease filter: mild soap and water or dishwasher.

■Door and exterior: mild soap and water, or glass cleaner applied to paper towel.

■Control panel: sponge or soft cloth and water.

■Stainless steel (on some models): mild soap and water, then rinse with clean water and dry with soft cloth, or use stainless steel cleaner.

■Turntable: mild soap and water or dishwasher.

■Rack(s) (on some models): mild soap, water and washcloth. Dishwasher cleaning is not recommended.

■Steamer vessel (on some models): mild soap, water and soft brush or dishwasher.

Installing/Replacing Filters and Light Bulbs

NOTE: A filter status indicator (on some models) appears in the display when it is time to replace the charcoal filter, and clean or replace the grease filter. See “Settings” section to reset filter status.

■Grease filters: Grease filters are on the underside of microwave oven. Clean monthly, or as prompted by filter status indicator. Slide the filter away from the tab area, and drop out the filter.

To reinstall, place end of the filter into the opening opposite the tab area, swing up the other end, and slide it toward the tab area.

■Charcoal filter: The charcoal filter is behind the vent grille at the top front of the microwave oven. The charcoal filter cannot be cleaned, and should be replaced about every 6 months, or as prompted by filter status indicator. Remove two screws on the vent grille, tilt the grille forward, lift it out, and remove filter. To reinstall, place the filter into its slotted area – wire mesh side up, replace vent grille, and secure with screws.

■Cooktop light: The cooktop light bulb is located on the underside of the microwave oven, and is replaceable. Remove bulb cover screw, and open the bulb cover. Replace bulb, close bulb cover, and secure with screw.

■Cavity light: The cavity light bulb is located behind the vent grille at the top front of the microwave oven, under the bulb cover, and is replaceable. Remove two screws on the vent grille, tilt the grille forward, and lift it out. Open bulb cover and replace bulb. Close bulb cover, replace vent grille, and secure with screws.

Microwave oven will not operate

Check the following:

■Household fuse or circuit breaker

If a household fuse has blown or a circuit breaker has tripped, replace the fuse or reset the circuit breaker. If the problem continues, call an electrician.

■Magnetron

Try to heat 1 cup (250 mL) of cold water for 2 minutes at 100% cooking power. If water does not heat, try the steps in the bullets below. If microwave oven still does not operate, call for service.

■Door

Firmly close door. On some models, if a packaging spacer is attached to inside of the door, remove it, then firmly close door.

If a message about the door appears in the display, the door has been closed for 5 minutes or more without the microwave oven being started. This occurs to avoid unintended starting of the microwave oven. Open and close the door, then start

the cycle.

■Control

Arcing in the microwave oven

Check the following:

■Soil buildup

Soil buildup on cavity walls, microwave inlet cover, cooking rack supports, and area where the door touches the frame can cause arcing. See “General Cleaning” in “Microwave Oven Care” section.

Turntable alternates rotation directions

■This is normal and depends on motor rotation at the beginning of the cycle.

Display shows messages

■A flashing “:” or “PF” means there has been a power failure. Reset the clock.

■A letter followed by a number is an error indicator. Call for assistance.

Odor and smoke coming from microwave oven during convection cooking (on some models)

Make sure control is set properly. Make sure Control Lock is off. Make sure Demo Mode (on some models) is off.

■This is normal for the first few convection cycles. The odor will dissipate with repeated use.
