Set the water tank, which has been filled with water to the MAX mark, to the set and power ON.
(Confirm that there is no water remaining in the oven cavity.)
Set the test mode to 10. (See How to operate test mode on page 11-1)
Press the START key.
The pump motor will operate for 30 seconds.
And then Microwave heating (for 1 minute) starts automatically.
Steam High operation (for 30 minutes) starts automatically.
After 2minutes, "CHECK" appears in the display automatically.

Measure the thermistor (grill) resistance using a tester with the thermistor
connecting connector pulled out of the wire harness.
The thermistor (grill) resistance is within its appropriate range.
Is the connector between the thermistor (grill) and wire harness either
disconnected or shorted?
Connect or repair the connector.
Replace the thermistor (grill).
