How many Ohms should a refrigerator thermistor read?

With the sensor warmed up to room temperature the sensor should read approximately 6.2K Ohms at 68°F. With the thermistor submerged is a glass full of ice water, the sensor should be very close to 32°F which should read approximately 16.3K Ohms.

Can you Ohm a thermistor?

All we need to test a thermistor is an ohmmeter or a multimeter that contains an ohmmeter. We then use the ohmmeter to check the resistance after various stages of our testing to see if the thermistor is behaving according to the characteristics of the thermistor. If it is, it is good.

How do you know if you have a bad thermistor?

The most common way to know if a thermistor is bad if it starts displaying inaccurate temperature readings. This can be caused by excessive heat, improper handling, a thermal mismatch, or a dip in resistance accuracy due to regular use and age. An open circuit can also lead to thermistor issues.

Where is the thermistor on a refrigerator?

Locate the thermistor in the refrigerator section; it’s under a small plastic cover attached to the surface of the back wall, side wall or ceiling. Release the thermistor cover and pull the thermistor out of the cover. Tip: See the parts list diagram for your refrigerator for help locating this component.

How do you read a thermistor?

Thermistor Specifications Usually expressed in percent (e.g. 1%, 10%, etc). For example, if the specified resistance at 25°C for a thermistor with 10% tolerance is 10,000 ohms then the measured resistance at that temperature can range from 9,000 ohms to 11000 ohms.

What causes a thermistor to go bad?

The cause of such failures are usually due to mechanical separation between the resistor element and the lead material, caused by handling damage, excessive heat, thermal mismatch, etc. The second most common failure mode is drift in resistance value as the thermistor ages, or parameter change.

Does my refrigerator have a thermistor?

Locate the thermistor in the refrigerator section; it’s under a small plastic cover attached to the surface of the back wall, side wall or ceiling.

Where can I find thermistor for the N811?

Below you will find the current thermistor for all N810, N811, N821, N822, and N841 models, regardless of serial number. Any numbers or letters after the model numbers are not important for this part.

Where is the thermistor on a Norcold refrigerator?

The photo to the left is a Norcold 1200 Series thermistor attached in the proper position on the cooling fins. If the Norcold refrigerator thermistor is attached on the wrong cooling fin, the fridge will appear to not cool correctly. Please start by checking that your thermistor is located properly.

Where can I find the Norcold N811 and N821?

Welcome to our Fridge Defend installation and Norcold N811, N820, N821, N823, N841, N842, NX811, NX841, NXA811, & NXA841 troubleshooting page. Before reading this page, please click here and view our wiring video.

How can I test the function of my Refrigerator thermistor?

Next we will discuss two simple ways to test the function of your refrigerator thermistor: 1) Use a thermometer in the fridge and compare the temperate to the temperature read out on the Norcold control panel while in the diagnostics mode. If the temperatures are similar, then the thermistor is working.
