Question about Dometic NDR 1292 Refrigerator

1 Answer

Thermistor with dinosaur board. Thermistor fails after a couple of months. Replaced two years in a row. Why is the thermistor failing. Frig freezes everything when thermistor fails. The resistance check in ice bath is fine on new thermistors when installed.

SOURCE: norcold n1095 not working on fine on LP

Yes. LP is direct heat to the exchanger. The thermistor operates through the control to the electric heater.

try to check the defrost thermistor and also make sure that the unit is working with the right FULL LOAD AMPERAGE by looking this we will know if it has exact refrigerant in the system.

Your problem seems to be fairly common but you may find a solution on the website at the link below:
Dometic recall
I linked to that page because of the recall that affects your model and I suggest you read consider it before you worry any further about the problems you are having. You can link to their home page from the recall message.

Hi, you have to troubleshoot the thermistor first before deciding on the cause of the problem. If you troubleshoot it and its bad, then you have to replace it again but if the thermistor is still good, then the fault is from somewhere else.

  • Attach an ohmmeter to the thermistor wires. You can pick up inexpensive ohmmeters at most hardware stores. Either of the ohmmeter's two connections can be attached to either of the thermistor's two connections.
  • Ohmmeters measure resistance; multi-meters may measure voltage, resistance and current. Use the portion of the dial marked for resistance (it will most likely have an omega symbol to denote ohms). Turn the dial until it shows the scale that gives the largest number of significant digits.
  • Check the ohmmeter screen for measured resistance. Compare to the given range for that particular model of your refrigerator.
  • If the thermistor measures in the specified range, it is not faulty and the problem lies elsewhere. If it does not, it is time to replace the thermistor again.
Try this out to know if the problem lies with the thermistor or not...

What is Code p2 on a Kenmore electric dryer?

error code indicates that the electronic control board detects an open thermistor (temperature sensor). This is usually caused by a failed thermistor. It can also be caused by a wiring problem or a failed control board.

To troubleshoot this problem, follow these steps:

Unplug the dryer to completely disconnect electrical power. Shut off the gas supply.

Remove the bottom front service panel as shown in the first image below.

Locate the thermistor on the blower housing. The second image below shows the thermistor. It should have a red/white and a black wire attached to it. Pull at least one wire off and measure the resistance across the leads of the thermistor using a volt/ohm meter. You should measure about 10K ohms (10,000 ohms) of resistance at room temperature. If you measure infinite resistance or get much different reading, then the thermistor will need to be replaced. Even if the thermistor reads the correct resistance at room temperature, it could still be defective and giving a bad resistance reading at higher temperatures.

If you suspect that the thermistor is good, check the wiring connection at the main control board (black and red/black wires on the P2 connector). The procedure for accessing the control board is shown in the third image below. With the dryer still unplugged, pull the P2 connector (see diagram of board) and check the resistance through the black and red/white wires. NOTE: The wires down below at the thermistor must be properly attached back onto the thermistor to properly check this circuit. If you get a much higher resistance (or infinite resitance indicating an open circuit) when measuring this circuit from the wires at the control board, then you could have a wiring failure that is causing your problem. If the resistance is the same, I recommend replacing the thermistor and testing the dryer to see if it operates properly.

If you still get the error code after changing the thermistor, then the control board will need to be replaced.

Why my 2012 hideout fridge is not getting cold

Sounds like the thermistor may bad. But first, gain access to the back side of the refrigerator and see if there is an ammonia smell or a yellow residue on the back of the refrigerator. If either of those are present then the cooling unit has failed and must be replaced.
If that is not the case then there are several ways to test the thermistor.

1: Place the end of the thermistor that is located inside the refrigerator into a glass of slushy water and read the ohms resistance on the plug end which is located on the back of the refrigerator. Compare your readings to the chart. If they are not in range then the thermistor is bad and needs to be replaced.

2: Unplug the thermistor from the circuit board. It will be the harness that has only two wires going into a hard plastic plug. Leave it unplugged for 24 hours and check the temp inside the refrigerator. If the temp has dropped then the thermistor is bad and needs to be replaced.

To replace the thermistor remove the thermistor sensor end from the plastic clip. Remove the plastic grommet from the back wall of the refrigerator. Tape the new plug end to the sensor head of the old thermistor and gently guide it through the hole. Once the taped head/plug passes through the hole you may complete pulling the new thermistor through from the back side. Only pull enough to allow you to plug the new thermistor in. Un-tape the plug end from the head and plug the thermistor in to the circuit board. Reinstall the cover over the circuit board and reinstall the access pane. There will be some sealing putty on the old thermistor harness. Remove that and gently press it back into the hole around the new thermistor harness inside the refrigerator and reinstall the plastic grommet. Install the sensor end into the plastic clip and install the plastic clip between the first and second fins. The higher up on the fin the colder the temp will be inside the refrigerator.

Have GE profile refrigerator. It is 3 years old.

OK check the Thermistor, the actual temperature sensor element, and or thermostat if it uses a separate feed.

GE GSH22KGM Frig not defrosting again

I would suggest replacing the # 4 thermistor , which is a 1 " long white piece with 2 white wires attached , clipped to the top of the coils . This thermistor , tells the main control board , the temperature of the coils and the board decides what to do next , such as defrost , end defrost cycle . Also , replace the defrost thermostat , the 1 inch cylinder with 2 wires going to it , which is also clipped onto the coils . This thermostat , cuts the heater off when it reaches a certain temperature , to keep the food from defrosting . It may also help , to replace the # 5 thermistor , which is below the coils , slid into a housing , with 2 white wires going to it also . This thermistor , tells the board , the actual freezer temp , so the compressor will cycle off/on , and the fan speed also . All 3 parts , are relatively not expensive . Be sure to get wire connectors because they do not come with these parts .
