The swith is not working and no light is coming in the cook or warm mode.

It may be making noise, and the light comes on, and the turntable goes around, but I'll bet it's not actually cooking (although that CAN happen). Try putting a cup of water in the microwave when this happens and see if it gets warm. If it does NOT get warm, then you just have a bad door switch. If it DOES get warm, then you have a stuck relay on the control board, and the control board will have to be replaced.

I would try troubleshooting the "defrost circuit". The behavior sounds like the microwave is cooking in the defrost mode, where it actively cooks then stops allowing the food to rotate and the heat to spread then actively cooking again.

To Activate Sabbath Mode:
To use the Warm Zone and/or Warm Drawer during Sabbath Mode,
press the WARM ZONE and /or WARM DRAWER keypad before
activating the Sabbath Mode.
1. Press BAKE.
2. Press the "+" or "-" key to set a temperature other than
350F (177C).
3. Press START.
For timed cooking in Sabbath Mode, press COOK TIME, then
the "+" or "-" keys to set the desired cook time.
4. Press TIMER SET/OFF for 5 seconds. "SAb" will appear in the
display.
To Adjust Temperature (when Sabbath Mode is running):
1. Press the "+" or "-" keypad. Each press of a keypad will
increase or decrease the temperature by 25F (14C). No
temperature will appear in the display.
2. Press START.
To Deactivate Sabbath Mode:
Press and hold TIMER SET/OFF for 5 seconds to return to regular
baking or press CANCEL/OFF to turn off the range

I would be interested to know just how long it is that the oven does stay lit. All ovens, gas and electric, cycle off and on throughout a baking cycle, to maintain the proper temp. If the flames or the power to the element were to stay on at full power for the life of the food's required time in the oven it would most likely wind up charred. The temp would simply continue to rise, up and up and up. If that's what it appears to be doing, then it's just working normally. If it goes out completely and stays off, doesn't come back on in a few minutes, then it may be in a keep warm mode. Many ranges have a TIMED BAKE cycle available, so you can set the clock to start the oven at such and such a time, cook the food and then shut off. Once it's finished with the cooking cycle, it goes into a keep warm mode, where it will come on for a short time and then go off, to maintain about 180 degrees. Not hot enough to really cook anything anymore, but hot enough to keep it warm for you when you get ready to eat.
If this seems to be the way it's acting, then look for the timed bake function on the console and set things back to a manual mode.

It sure would help us to help you if you could get the model number off of the bottom of the unit. I can probably locate a user's manual with that information. Try this site to locate the manual: (my best guess without a model number)

Find the little blue print that says enter security code and then you can dounload the manual.
The settings should be OFF High 4 High 6, Low 8 Low 10 and warm.

1. Place food in stoneware according to recipe.

2. Plug in Smart-Pot™ slow cooker. The Power light will begin to flash

indicating that the unit is plugged in, but not turned on.

HOW TO PROGRAM YOUR SMART-POT™ (CONT.)

3. Push the Cook Time button to scroll through the timed cooking

options. Push once and the 4 hour light will illuminate, twice and the

6 hour light will come on, etc. Select the time based on the length of

time indicated in the recipe. Two time options are usually given. The 4

and 6 hour settings are the HIGH temperature setting and may be

used when you want your food done quicker. The 8 and 10 hour

settings correspond to the LOW temperature setting and is used for all

day cooking. In addition your Smart-Pot™ can be set to the Warm

Setting by scrolling through the timed cooking options until the warm

light illuminates.

NOTE: The Warm setting is for keeping already hot food warm. Do not use

the warm setting to cook or reheat food.

4. When the cooking time is completed, the Smart-Pot™ slow cooker will

automatically shift to the Warm setting and the Warm light will come

on. NOTE: We do not recommend using the Warm setting for more

than 4 hours.

5. To turn the Smart-Pot™ off push the OFF button. Unplug unit from the

wall outlet.

6. For other recipes that give a range of times, select the time closest

to the setting on your Smart-Pot™. For instance a recipe calling for

cooking time of 7 to 9 hours on LOW, set your Smart-Pot™ to 8 hours.

NOTE: If power goes off then power light will blink and settings must be

reset. If cook time is changed before the cycle is complete the time will
reset to the new setting.

If I unplug my crock pot, hold the On button down, then plug it back in my "warm" light comes on. Might work for you?

try to push the center button inside the cooker using anything not your hands.. then switch to cook mode, if the switch will not come back to warm mode then the problem is the spring on it.. you need to open the cooker and try to remove the spring then stretch it..

Push the COOK TIME button, if the time changes then if you leave the number of hours between 1 and 6, and press the ON/OFF button, it will cook on high that many hours. If you leave the number between 7 and 10, and press the ON/OFF button, it will cook on low that many hours. If you leave the number at "0" then the slow cooker will cook on WARM. If the COOK TIME button does not work, unplug the slow cooker, hold both the ON/OFF button and the COOK TIME buttons down and plug it into a wall socket. After the lights flash a few times, release the buttons. the switches should work.

bad thermostat . there are no parts made for this model . sorry

Check if the oven is in AUTO cook mode. It should be in MANUAL cook mode , check if it has a MANUAL mode button. Sometimes resetting the clock will put it back into MANUAL mode.
