How many ohms should a refrigerator thermistor read?
You will need to unplug the refrigerator before starting this test. Set your multi-meter to ohm. Step # 11 – Take an OHM reading from your multimeter; it should be around 16.3 Kilo-Ohms (16,300 Ohms). Any reading that is more or less than 5% from this value means your thermistor is bad and will need to be replaced.
What happens if a thermistor fails in refrigerator?
The thermistor senses temperature changes in the refrigerator and sends the control board a signal about the temperature change. If the thermistor fails, the refrigerator won’t stay at the temperature you set, resulting in items either freezing or spoiling because it’s too cold or too warm.
How do I know if my fridge temperature sensor is bad?
Here are some signs that your fridge has a faulty thermostat and some troubleshooting tips to help you deal with them.
- The Refrigerator Is Not Cool Enough.
- Unusually Cold Refrigerator.
- Refrigerator Temperature Fluctuation.
- Sub-Zero Refrigerator Temperature Troubleshooting Tips.

Can you wire a thermistor backwards?
Note: Thermistors are not polarized….so you can’t hook them up backwards.
Can you repair a thermistor?
Order a thermistor and pull the old one off and replace it. This requires soldering and some bravery since the thermistor wiring path is complex. You will also need a thermal sensor and high temperature thermal paste.
Can I bypass thermistor?
This is not specifically related to overclocking. Generally speaking, a thermister is a resistor that is sensitive to/affected by ambient heat. When the ambient heat changes, it’s value will change. You can bypass it with a regular resistor, but you have to know the value associated with the thermister.
What happens if thermistor is bad?
When a thermistor is failing, it’ll display incorrect temperatures, or you’ll see impossible temperature fluctuations. For example, you may initially get a reading of 210 degrees only to see the temperature drop to 189 degrees and jump back up again.
Is there a positive and negative on a thermistor?
There are two types of thermistors: Negative Temperature Coefficient (NTC) and Positive Temperature Coefficient (PTC).
How do you fix a thermistor wire?
In this case, needle nose pliers will work well enough. Get the wires in place, and squeeze. If there is room, squeeze in two places. Tug lightly on the wires, they should stay together – if they slip loose under a gentle pull, try again but squeeze harder.
Can I splice thermistor wires?
Yes you can repair the wires on the thermistor, Flexible Silicone insulated wire is the best bet.
