Start button does not start the power - Neff H5470N0GB Microwave Oven

Safety system locking out the start switch. Door not closed, mode and timer not set etc.

This is from Page 16 in the users manual...

For simple, one-stage cooking, you only need to set the cooking time. The power level is automatically set to High.

If you want to set the power level to any other level, use the Power Level button.
1. Use the number buttons to set a cooking time. You can enter a time from one second to 99 minutes and 99 seconds. To select a time greater than one minute, enter the seconds too. (For example, to set a cooking time of 20 minutes, enter 2, 0, 0, 0.)

2. If you want to set the power level to a level other than High, press the Power Level button, and then use the number buttons to enter the power level.

3. Press the ENTER/START button to begin cooking. If you want to change the power level, press the STOP/ CLEAR button before you press the ENTER/START button, and then enter all the instructions again.

Try pressing and adjusting the power level before setting the cook time, or maybe before pressing start. Worked on my Panasonic

You have to put the cook time in first and then you press the power level button (just below the number 7 on the keypad) and put the power level in. The choices are 1 through 10. Fifty percent is probably power level 5. Once you have put in the power level, just push the Start button and it will start cooking.

would probably help us to understand if you would please re word your question. Not too clear, sorry

i have power and light is on can not press any numbers or start button or any other button.it keeps on peeping steady

Press "Power" until you get to the level you want. Then enter the # of minutes on the keypad (CANNOT use express cook times.) An alternating runnig hum will let you know the setting is working.

The owner's manual is here. On page 10 we find:

Replaced with different microwave. Amanna microwave works fine on both circuits. Would not recommend Whirlpool for RV use.

Thanks
