Could be element could be Hi limit thermostat could be control. In that order. First step is turn breaker off and remove element to make sure the wires are still connected to back of element. Visually inspect element very good for burns or a white powder residue signally the element burned up. Next step is harder, need to remove the oven and take off back panel, there you will find the hi temp thermostat. Check for continuity, if none replace.
In this tip I will show you how to easily test your Microwaves power. If it is sufficient, or if it is not heating effectively anymore.
Non heating Microwaves are a common issue, and the most likely component that is faulty is the Magnetron - These days Magnetron's are quite expensive (usually about 50% the price of a new Entry Level Microwave). Low heating could mean a Magnetron becoming faulty (unlikely, as a Magnetron either works, or it doesn't work)
Tools required: A Normal Glass (Heat-resistant, in other words Microwave friendly), Water (Room Temperature) , a Centigrade Thermometer (Can get this at any Pharmacy)
Procedure: 1) Fill a glass with approx. 125 ml water. Use water at room temperature (from the tap), avoid using refrigerated water as this will work against the test we are doing. 2) Measure the initial temperature of the water with the thermometer (It should be between approx. 10 & 20 degrees). 3) Place the glass with the water about 2 cm away from the center of the Microwave Oven plate. 4) Heat the water at full power (The highest setting possible on your Microwave) for 70 seconds. 5) Stir the water (For 5 - 8 sec). 6) Measure the final water temperature with a thermometer. 7) If the increase is 45 degrees or more, then your microwave is heating sufficiently, if not it could mean replacing the Magnetron, or purchasing a new Microwave.

Hi, Look at the home breaker box or fuse box to check for a tripped breaker or blown fuse. If your oven is not heating because there is no power, you may need to replace a fuse or reset a breaker. Also check the power outlet to confirm that the oven is plugged into the outlet securely.
Press the "START/ENTER" button to get the oven to heat after selecting your temperature, if you cannot get it to heat. If you do not press this button within five minutes of setting the temperature, the oven heating cycle will automatically be canceled and the oven control panel will return to displaying the sign.
Calibrate the temperature setting on the oven if it is not heating at a temperature that you like. Do this by holding down the "BAKE" button until the current calibration setting appears, which will be a temperature followed by "CAL." Use the up and down arrow button to increase the temperature and press the "START/ENTER" button once you are done. You can increase in five degree increments up to an additional 35 degrees.
Call the Whirlpool customer interaction center at 800-253-1301 if your troubleshooting fails to fix your heating problem. The customer service representative can give you contact details for a local service technician so that you can have the oven looked at by a professional.
If it's American, the temperature probably reads as fahrenheit. If so, 20 degrees F is 12 degrees F below freezing which converts to only -6.67 degrees Celsius.
Domestic freezers should be set to -17 degrees Celsius (= 0 degrees F), so the beeper is warning you that the freezer compartment is far too warm. If it's working correctly and has the temperature control set correctly, then it should achieve the correct temperature if you leave it for 24 hours and do not open the door nor try to use the ice dispenser. If the freezer is full of unfrozen items and so has to cool those down as well, then it may take even longer to reach the correct operating temperature.
Te operating manual for your appliance will tell you how to set the temperature correctly and whether it's possible to select between fahrenheit and Celsius scales. Most models allow you to set an override on the beep alarm as well. I cannot guide you on this without knowing the exact Samsung model.
Also the fact it is a convection oven could mean the oven temperature sensor is not picking up the oven temp. it is not telling the machine it is there by the board seeing its resistance, the unit will shut off as a safety feature. The oven sees temperature by reading the value of a temperature dependent resistor. As the temperature changes so does the value of the component ( oven temp sensor) that way the unit determines the temperature inside the unit. Sometimes those sensors will break since they are in the area with the heat and moisture, they get old and break.
The microwaveoven per se, does not have a temperature. The microwaves that are generated simply heat up the water molecules in the item that they hit. So, the maximum temperature, I guess, would be 100 degrees C or 212 degrees F, the boiling point of water.
When the food you're baking is done on top but not on the bottom--or when baking just takes far too long to finish--the bake element may be burned out.
You may get fooled into thinking it's working, because the oven is hot inside. But many electric ovens use the broil element, too, during the preheat and bake cycles. So the food may be getting heated only by the broil element, which causes poor baking results.
If the bake element is burned out, replacing it should solve the problem. Otherwise, you need to further troubleshoot the oven's electrical system to locate the defective wire or component.
When the temperature is consistent but too high or too low, it could be one of several different things. First check to see if the thermostat sensing bulb has come loose from its holder. It could be lying on the floor of the oven or resting on the heating element. This would cause the oven to not heat correctly.
If the thermostat bulb is not dislodged, it's likely that the thermostat or sensor is either mis-calibrated or defective.
Electronic ovens with a digital display use a sensor to monitor oven temperature. To solve temperature problems for these models, you may need to replace the sensor. On some digital-display models, you can calibrate the temperature using the key pad. See your operator's manual for details.
Ovens without a digital display often use a mechanical system for controlling temperature. On many of these units, you can remove the thermostat knob and adjust the knob itself to more accurately represent the actual setting of the thermostat.
If, when you remove the knob, there's a screw on the back of it with a small calibration plate, you can loosen the screw, adjust the plate, then tighten the screw again. If the knob isn't adjustable, and the oven temperature is off by more than 30 to 40 degrees, you need to replace the thermostat to solve the problem.

The
following test will provide a suitably accurate measurement of the
output power of any microwave oven. Variations or errors in performing
this test will produce uncertain results. If the line voltage (from the
electrical outlet) is low, the magnetron output will be correspondingly
low.
Equipment needed:
- Microwave safe container with 1000 mL (1 Liter) gradation.
- Fahrenheit or centigrade thermometer
Procedure:
Pour
exactly 1000 mL (1 Liter) of cool tap water into the container. Using
the thermometer, stir the water, then measure and record the
temperature. For accurate results the water should be about 60 degrees
F (20 degrees C).
Place the container on the center of the
oven cooking shelf (do not leave the thermometer in the container and
remove any metal racks), and heat the water (at full power) for 63
seconds. Use the second hand of a watch, not the oven timer.
After
the heating time is completed, immediately remove the container, stir
the water, re-measure and record the temperature of the heated water.
Subtract the starting water temperature (step 2) from the ending water temperature (step 3) to obtain the temperature rise.
To
determine the output power in watts, multiply the total temperature
rise by a factor of 38.75 if you're using a Fahrenheit thermometer or
by 70 if you're using a centigrade thermometer.
2) If it's not hidden either behind the
grille or control panel, they may have left it out as a cost-savings measure.
