Troubleshooting appliances
Microwaves are important kitchen appliances. They save time and make cooking easier. But, they can they can experience issues over time. One common problem is with the thermostat. If your Samsung microwave isn’t heating properly, it might be due to thermostat malfunctions. In this blog post, we’ll explore common thermostat issues and how to troubleshoot them. Let’s ensure your microwave runs like new again.
Understanding Your Samsung Microwave
Samsung microwaves are equipped with a range of features aimed at to make your life easier. From sensor cooking that automatically adjusts cooking times to ceramic enamel interiors that are easy to clean, these appliances are built for modern living. But at the heart of it all lies the thermostat, a small but crucial component that ensures your food is heated safely and evenly.
The Importance of the Thermostat
The thermostat is your microwave’s safety guard. Constantly monitoring the temperature inside the oven to prevent it from overheating. A malfunctioning thermostat can lead to a range of problems, from undercooked food to potential safety hazards.
Common issues
Symptoms of Thermostat Problems
- Food is undercooked or overcooked: If your bunny chow is still cold in the middle or your curry is burning, a faulty thermostat could be the culprit.
- Microwave shuts off unexpectedly: Does your microwave suddenly stop mid-cycle? This could mean that the thermostat is tripping prematurely.
- Burning smell: A burning smell emanating from your microwave is a serious red flag and could signify a thermostat malfunction.
- No heat at all: In some cases, a faulty thermostat may prevent your microwave from heating altogether.
Causes of Thermostat Malfunctions
- Power surges: Load shedding and the subsequent power surges can wreak havoc on sensitive electronic components like thermostats.
- Overheating: Cooking large quantities of food for extended periods can cause the microwave to overheat, potentially damaging the thermostat.
- Food spills: Spilled food or liquids can seep into the thermostat, causing it to malfunction.
- General wear and tear: Like any appliance, thermostats can simply wear out over time.
troubleshooting steps
Try our suggestions
1. Checking the Thermostat Settings:
- Power Level: Make sure you’re using the appropriate power level for your dish. Cooking on high power for too long can trigger the thermostat.
- Cooking Time: Double-check that you’ve set the correct cooking time. Overcooking can lead to overheating and thermostat issues.
2. Inspecting the Thermostat Sensor:
- Location: The thermostat sensor is usually located on the inside wall of the microwave.
- Cleanliness: Carefully clean the sensor with a damp cloth. Food debris or grease can interfere with its function.
- Damage: Inspect the sensor for any signs of physical damage. If it’s bent or broken, it will need to be replaced.
3. Testing the Thermostat with a Multimeter (for the electrically inclined Durbanites):
- Safety First: Always unplug your microwave before attempting any electrical testing.
- Continuity Test: Use a multimeter to test the continuity of the thermostat. If there’s no continuity, the thermostat is faulty and needs replacement.
- Caution: If you’re not comfortable working with electrical components, skip this step and seek professional help.
4. Resetting the Microwave:
- Power Cycle: Unplug your microwave for a few minutes and then plug it back in. This can sometimes reset the internal circuitry and resolve minor glitches.

How does a microwave thermostat work?
A microwave thermostat serves as a safety device designed to prevent the microwave from overheating. It functions by continuously monitoring the temperature inside the microwave. Should the temperature exceed a certain threshold, the thermostat will automatically shut off the microwave’s power.
Here’s a breakdown of how it works
- The thermostat is positioned near the magnetron. The magnetron is the part of the microwave that generates the heat.
- The thermostat contains a switch made of two different metals. These metals expand and contract at different rates when heated.
- When the temperature gets too high, the metals expand and bend. This causes the switch to flip and cut off the power to the microwave.
- Once the microwave cools down, the metals contract. This causes the switch to flip back and turn the power back on.
Think of it like this
Imagine a bimetallic strip, similar of metal glued together. As it heats up one metal expands more than the other, causing the strip to bend. This bending action can be used to open or close a switch. That’s essentially how a microwave thermostat works.
Key takeaway: The microwave thermostat serves as an essential safety feature, preventing potential fires.
