Hi my microwave smh8165 has no power for some reason i pressed start instead off the timer while cooking there was nothing in microwave and just shut down no power , no display , nothig tried to unplug , and shut off breaker still nothing anyway maybe its the internal (thermal) fuse can i change that and if so how...

If you're talking about a microwave oven:
[1] plug the mains cord in to the wall socket
[2] switch the socket on
[3] put food to cook on glass turntable, never use empty oven.
[4] close oven door fully until it clicks
[5] set the power
[6] press 'start' or turn the timer-dial,depending on your model.
It will start to cook immediately.
The humming sound is the energy heating the food in timed bursts of power.
If nothing happens or it won't cook, post clear description of fault with problem, make, model.
Hope this helps,
Clive.

Possibly a bad door switch behind the holes where the latch hooks go into. Usually with the bad switch the timer counts down but nothing runs. It all depends on which switch is bad. Usually 3 switches inside.

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

switch if off completelty for approx 5 mins and then power it back on

HELLO.

Solution to your microwave problem is given as below.

* 1 Set your Daewoo microwave on a countertop near an electrical outlet and plug it in. Open the door and place the circular roller guide in the center of the oven cavity, then place the glass cooking tray over it.

* 2 Set your food on a microwave-safe dish and then put the dish on the cooking tray and close the door. Make sure that it latches properly.

* 3 Turn the upper knob to select a power level. Power levels include "Defrost," "Med-High," or "High." If your Daewoo has a touch pad, touch the "Microwave" button once to set the highest power level. Touch it consecutive times to lower the power level.

* 4 Turn the lower knob to set the cooking time. For cooking times less than two minutes, turn the knob up past the two-minute mark, then back to the correct time. For touch pad models, enter in the cooking time with the numerical keys and then press "Start."

* 5 Open the door at any time to stop the cooking and check the temperature of your food. Shut the door to automatically continue cooking, or turn the timer knob to the right to add more time. For touch pads, press the "Stop/Clear" button, then key in a new cooking time and press "Start."

* 6 Open the door when the timer reaches the "Off" position and take out your food.

Thanks.

Assuming its the same as my Hamilton Beach, you first enter the cooking time, but don't press start yet, instead press power, then a number button 1 - 9 for the power level 1 for 10%, 2 for 20% etc. THEN press start as normal

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

COOKING IN ONE STAGE
1. Press the POWER button; the Microwave and High
Cook indicators will light and “PL 10” will light in the
display.
2. Press the POWER button different times to set the
desired power; the display will show the percentage
you chose. If selecting power level 70%-10%, the
Low Cook indicator will light instead of the High
Cook indicator.
3. Press number keys to set the desired cooking time.
OPERATION(CONTINUED)
4. Press the START/+30SEC. button to start cooking;
the Microwave and one of the Cook indicators will
blink and the display will countdown the remaining
cooking time in minutes and seconds. It will beep
five times when cooking is completed.

Hi! I just purchased the same microwave, and came online to find the solution. I was then able to find the correct answer to this problem. On this model, Emerson does not put a "time cook" button for odd cook times such as 15 seconds. Instead, they have you push the "Power Button" prior to setting the cook time.

If you want to cook on full power, press the power button once, and then enter your cooking time and press start. If you want to cook on 50% power or 30% power or something like that, push the "Power Button" several times until the appropriate power level is displayed, then enter the cook time and press start.

The reason that it starts up right away when *********** pushes the 1 button is because Emerson has the quick cooking feature for 1 minute through 6 minutes. You only have to push the number once to get the 1 minute cook time or anywhere through 6 minutes respectively.

Hope this helps!
