Whirlpool WMH73521CS Owner's Manual

For list of preset programs, see the Quick Reference Guide provided with your model.

Touch COOK TIME, touch number pads to enter time, touch COOK 
POWER (if not 100%), touch number pads to enter power level (10-90), 
then touch the Start control.

If programming additional stages (up to three), touch OPTIONS/
CLOCK to enter programming for the next stage, then enter the cook 
time and cook power of each, then touch the Start control.

A sensor in the microwave oven detects moisture released from food as 
it heats, and adjusts the cooking time accordingly.

Make sure microwave oven has been plugged in for at least 1 minute. 
Use microwave-safe dish with loose-fitting lid, or cover microwave-safe 
dish with plastic wrap and vent. For optimal performance, wait at least 
30 minutes after convection cooking or grilling (on some models) before 
sensor cooking.

At the end of any cycle using less than 100% cook power, “PRESS 0 
TO ADD MORE TIME” scrolls in the display. Enter the additional time, if 
desired, and start the microwave oven. The cook power for all non-
sensor cycles will be the same as in the finished cycle, but may be 
changed. If Add More Time is used after a sensor cycle, the cook 
power will be 100%, but may be changed.

Adjust doneness for automatic cooking functions by touching COOK 
TIME repeatedly to scroll through “NORMAL,” “MORE DONE” or 
“LESS DONE” within the first 20 seconds of starting the cook cycle. 
Doneness cannot be adjusted for Defrost functions.

Hot cooked food can be kept warm in the microwave oven. The Warm 
Hold function uses 10% cook power. Warm Hold can be used by itself 
or can be programmed to follow a cooking cycle. Opening the door 
during Warm Hold will cancel the function.

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.

the microwave oven cavity, do not use metal or sharp utensils or 
scrapers, or any type of abrasive cleanser or scrubbers.

area, swing up the other end, and slide it toward the tab area.

■

Charcoal filters: The charcoal filters are behind the vent grille at 
the top front of the microwave oven. The charcoal filters 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.
