NOTE: If the water takes longer than 2 minutes to heat, this may indicate
either the operating voltage is lower than 110 volts or there is a problem
with the microwave oven.
NOTE: Many of the problems listed in the chart below may be solved by power cycling: unplug microwave oven or disconnect power. After one minute,
plug in microwave oven or reconnect power.
