Open Question

Can a dryer "blow" an inlet thermistor?

I had a GE technician in my house and he told me that the inlet thermistor is bad. He tested the resistance in it an it was very low. I bought a new thermistor and replaced it. The dryer still wold not heat. I ran the service mode and still get a message that says that my intlet thermistor is a problem. I then tested he resistance in the new thermistor and the resistance was again negligible. Can the dryer "blow" this part or could the new thermistor be defective?

    We have had a second thermistor sent to us from GE. We replaced it along with the gas line. The dryer is still not heating. I'm pretty sure that there is a reset button that we need to find in order to clear the errors.

    The machine is 8.5 years old. The second technician replaced some board. He determiend that the problem was the inlet thermistor but didn't have one with him.

Did you end up replacing this thermistor? If so did that solve the problem? We are having the same issue and I don't want to waste time and $$.

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.

How do i Measure the resistance of each thermistor


Dryer getting over heated. Check your exhaust vent for good air flow. Also your operating thermostat could be defective overheating the dryer and blowing your thermal fuse. To check resistance set your multimeter to ohms and connect your leads to thermistor make sure to disconnect the wires from the thermistor.

I have a ge model dcvh680gj2ww i turn it on and and works for a cuaple of sec and shuts off


Check the thermistor on the blower housing. The thermistor should have a resistance reading. At room temperature it should read around 10,000 Ohms. You can test this with a multi-meter. This usually cause the problem you have described. Here is the part to order in case you find it bad. Post back your results.

F25 error code


Having an error code on your appliance can be an inconvenience and I know how important it is to have a good working dryer.

The "F25" indicates the INLET THERMISTOR is shorted or the INLET THERMISTOR circuit is shorted. If you replaced the inlet thermistor and control board then it may have bad inlet thermistor circuit. You should disconnect the thermistor circuit connections at the thermistor and control board and test the thermistor circuit for continuity. Check the circuit to see it happens to be open or shorted with an ohm meter.

The inlet thermistor is located on the side of the heating element housing is a thermistor and high limit combination. The part number is 8557403. The inlet thermistor portion of the thermistor/high limit will have two solid red wires connected to it. It could have faulty new thermistor or it could have an open or shorted thermistor circuit or a faulty control board. The thermistor can be checked with and ohm meter. Disconnect the two red wires and place the ohm meter leads across the two terminals. At room temperature it should measure approximately 50k ohms of resistance. If it measures 50 k, then it should be reconnected and then the sensor circuit disconnected from the control board and retested at the harness wires to see if you get the same measurement reading. If it does measure the same, and it continues to display F25, it could have a faulty control board.

What is your model number?

My dryer is a model 110.85862400 - it appears to be drying on very high temperature only. I ran it and it was very hot. Turned it off let it cool and ran it again and it still was very hot. Let it cool,...


Your dryer doesn't have a cycling thermostat and instead, it uses a thermistor located on the blower housing. The thermistor used to monitor and attain the correct dryer temperature. It is likely faulty and doesn't give the appropriate resistance for the right dryer temperature. This will eventually lead to thermal fuse blowing and the dryer will stop working. Access the thermistor to check its resistance then refer to thermistor resistance and temperature table below. Replace the thermistor if the resistance is not found in the table.

Disconnect power then remove the two hex-head screws from the bottom flange of the toe panel then pull the panel down and off the cabinet.

Remove the hex-head screw from the lint duct bracket and remove the bracket. Remove the two hex-head screws from the lint duct and remove the duct to expose the thermal fuse on the blower housing.

Remove at least one of the wires from the terminals of the thermistor when measuring its resistance. Remove the two-hex-head screws securing it to the blower housing when replacing it and install the new one. Reassemble in reverse order of the disassembly steps.

DLG5932 gas dryer blows its overheat fuse, after reset by technician it heated fine. On the first load of laundry it heated for a while, and then blew out the overheat fuse again. Dryer was totally cleaned...


The dryer is overheating but is not the fault of the vent. Have the technician check the operating thermistor on the exhaust behind the blower wheel. This thermistor acts as the thermostat for this dryer and if it is off will either not allow the dryer to heat or will overheat the dryer like in your case and cause the thermal fuse to blow out or trip. He should measure ohms and according to temperature and should have access to what it should measure. If the thermistor measures bad, replace thermistor. If this measures good the control board is reading the thermistor wrong and the board will need to be replaced.
Thank you
