How To Test Your Defrost Thermostat & How They Work
How do I know if my defrost thermostat is bad?
If your freezer isn’t defrosting properly, one possible reason is a bad defrost thermostat. This component controls the amount of time that the defrost cycle runs, so if it’s not working correctly, the defrost cycle will either run too long or not long enough. Here are a few signs that your defrost thermostat may be bad:
-The freezer temperature is too high -There is ice buildup on the freezer walls or ceiling -The freezer coils are frosted over
-There is water on the floor in front of the freezer If you notice any of these problems, it’s a good idea to check the defrost thermostat to see if it’s the cause. To do this, simply remove the thermostat from its housing and test it with a multimeter.
If the thermostat is defective, it will need to be replaced.
What happens when refrigerator defrost thermostat goes bad?
When a refrigerator’s defrost thermostat goes bad, the fridge will no longer enter the defrost cycle. The defrost cycle is important because it helps to prevent ice buildup on the evaporator coils. Without the defrost cycle, the ice will eventually become so thick that it will prevent cold air from circulating properly, causing the fridge to become less efficient.
In some cases, the ice can even cause the evaporator coils to crack. If the defrost thermostat is not replaced, the ice will continue to build up and cause the fridge to stop working entirely.
What happens when defrost sensor goes bad?
If your freezer’s defrost sensor goes bad, it can cause a number of problems. The most common problem is that the freezer will stop defrosting itself. This can cause ice to build up on the evaporator coils, which can eventually lead to your freezer not cooling properly.
Additionally, a bad defrost sensor can cause your freezer to run more frequently, which can increase your energy bill. If you notice any of these problems, it’s important to call a refrigerator repair technician to diagnose and fix the problem.

-The food in the refrigerator is spoiling quickly. -The freezer section is not freezing properly. -There is ice build-up on the inside of the freezer.
If you notice any of these symptoms, it is important to have a qualified technician check your refrigerator to determine if the thermostat is the problem.
Symptoms of a bad refrigerator thermostat
If your refrigerator isn’t staying cool, it’s possible that the thermostat is to blame. Here are some common symptoms of a bad refrigerator thermostat:
-The fridge isn’t getting cold enough
-The fridge is getting too cold -The fridge is cycling on and off more than usual -The fridge is making strange noises
If you’re experiencing any of these issues, it’s best to call a refrigerator repair technician to take a look. Trying to fix a refrigerator thermostat yourself can be dangerous, so it’s always best to leave it to the professionals.
How to test a defrost thermostat
If your refrigerator has a Frost-Free feature, it has a defrost thermostat. The defrost thermostat turns the refrigerator off when the set temperature is reached and then back on when the temperature rises above the set temperature. If your refrigerator does not have a Frost-Free feature, it has a manual defrost thermostat.
The manual defrost thermostat turns the refrigerator off when the set temperature is reached and then back on when the temperature rises above the set temperature. To test your defrost thermostat, first locate it. The defrost thermostat is usually located in the freezer compartment, near the evaporator coils.
Once you have located the defrost thermostat, use a multimeter to test it for continuity. Set your multimeter to the ohms setting and place the probes on the thermostat terminals. If the multimeter beeps, this indicates that the thermostat has continuity and is working properly.
If the multimeter does not beep, this indicates that the thermostat is not working and will need to be replaced.
How to test defrost thermostat with multimeter
If your refrigerator isn’t defrosting properly, it could be due to a faulty defrost thermostat. To test the defrost thermostat with a multimeter, first unplug the refrigerator. Then remove the thermostat from its housing and disconnect the wires.
Next, set your multimeter to the ohms setting and touch the probes to the thermostat’s terminals. If the reading is infinite, that means the thermostat is open and needs to be replaced. If the reading is zero, the thermostat is shorted and also needs to be replaced.
Refrigerator defrost thermostat location
If your refrigerator has a manual defrost system, the defrost thermostat is usually located on the wall behind the coils. To access it, you’ll need to remove the back panel of your fridge.
The defrost thermostat is a small switch that controls the defrost cycle of your fridge.
It’s usually round and has a white or silver face. The numbers on the face represent the temperature in degrees Fahrenheit. The defrost thermostat is connected to the evaporator coils.
When the coils get too cold, the thermostat switch closes and the defrost cycle begins. A fan blows warm air over the coils to melt the ice. If your defrost thermostat is not working properly, your fridge will not defrost properly.
This can lead to ice buildup and decreased efficiency. If you think your defrost thermostat is not working, call a qualified repair person to diagnose the problem.
How does a defrost thermostat work
If your fridge is feeling a little frosty, there’s a good chance the defrost thermostat is to blame. This handy little device is responsible for regulating the amount of time the fridge spends in defrost mode, ensuring that ice buildup is kept to a minimum. But how does it work?
The defrost thermostat is essentially a switch that turns the fridge’s defrost cycle on and off. It’s usually located near the evaporator coils, and contains a bimetallic strip that bends when exposed to heat. As the strip bends, it makes contact with the switch, completing the circuit and allowing current to flow.
When the fridge is first turned on, the bimetallic strip is cool, so the switch is open and the defrost cycle is off. As the fridge warms up, the strip begins to bend, eventually making contact with the switch and turning the defrost cycle on. The cycle will run for a predetermined amount of time, typically around 20 minutes, before the strip cools down and the switch opens again, turning the cycle off.
If your fridge isn’t defrosting properly, it’s likely that the defrost thermostat is the culprit. To test it, simply remove the thermostat from the fridge and place it in a cup of hot water. If the thermostat doesn’t click on within a minute or so, it’s likely defective and will need to be replaced.
How to tell if your fridge is defrosting
If you think your fridge might be defrosting, there are a few things you can look for. First, check the temperature inside the fridge. If it’s warmer than usual, that’s a sign that the fridge isn’t working as well as it should be.
Another telltale sign is frost buildup on the inside of the fridge. If you see frost, that means the fridge isn’t able to keep the cold air in, and that can lead to food spoilage. If you’re not sure whether or not your fridge is defrosting, it’s best to call a repair person to take a look.
Defrosting fridges are a serious problem and should be fixed as soon as possible to avoid food spoilage and other issues.
Defrost thermostat temperature range
Most fridge-freezers will have a defrost thermostat with a temperature range of between 0°C and 8°C. The defrost thermostat is a bimetallic strip which is sensitive to changes in temperature. As the strip cools, it bends and this activates the defrost cycle.
When the temperature rises above the set point, the strip bends back and deactivates the defrost cycle.
Samsung defrost sensor test
The refrigerator’s defrost sensor is located in the defrost heater assembly. The function of the defrost sensor is to monitor the temperature of the evaporator coils during the defrost cycle. If the coils get too cold, the defrost sensor will turn off the defrost heater to prevent the coils from freezing.
To test the defrost sensor, first make sure that the refrigerator is in defrost mode. Then, using a multimeter, check for continuity between the two terminals on the defrost sensor. If there is continuity, the sensor is working properly.
If there is no continuity, the sensor is defective and will need to be replaced.
If your freezer isn’t defrosting properly, it might be due to a bad defrost thermostat. Some common symptoms of a bad defrost thermostat include frost build-up on the evaporator coils, ice build-up in the freezer, and the freezer temperature rising. If you suspect your defrost thermostat is bad, you should call a qualified appliance repair technician for diagnosis and repair.
