Without a chart in front of me, I can't tell. But you can download a thermistor coefficient chart from Tranes site or any of many different manufacturers. But why don't you slowly elevate the temperature of the thermistor to 77 degrees with a thermocouple style sensor taped to it and check it specifically AT 77 degrees ? Use a hair dryer on low and wave it a couple feet away to slowly bring it up to temp while monitoring the display on your digital DVOM..

A 10,000 ohm at 77 degree thermistor is very much a standard thermistor throughout the HVAC industry. I have charts at home, but at present am not near there.

Why is my Frigidaire Affinity dryer showing E71 after I replaced the heating element


Error Code E71 - Outlet Control Thermistor open circuit -- Outlet Control Thermistor or wiring defective.

Check resistance of Outlet Control Thermistor, and check wiring for open circuit. Resistance should be between 4.9K Ohm and 6.2K Ohm at room temperature (68-77° F or 20-25° C). Replace Outlet Control Thermistor and/or wiring and retest.

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.

The thermister, located on the blower housing will need to be checked. This will keep the dryer from running if the thermister is out of tolerance. At room temperature of 77 degrees it should read 10K ohms. If it is out of tolerance, you will need to replace it. Here is the part to order.

My Maytag dryer is flashing a 6


That error is for the "Thermistor"
Check for resistance ( 50-300K Ohm) across thermistor.

If the resistance is out of tolerance, Replace the thermistor.

Here is a link to the part you need.

E5 code no top on the E


The code is T5 and that is the thermistor
Check for:
- Clogged lint screen.
- Restricted vent system.
- Check Thermistor resistance. Thermistor resistance 10K ohms at 25 C 77 F (2P-Blue & Red wire)
- Check for diagnostic code 1
Use tech sheet in machine to enter diagnostics mode

I have a code poping up when i start the drying cyle the code is E5 but when it showes the code yhe top bar of the E dose not show so im guessing its an E


I believe you are describing a tS code.

If it is tS showing it is an indication that the termistor is shorted. The thermistor is the temperature sensing device used on this dryer.

Before replacing the themistor check for a clogged lint screen or dirty vent pipe.

If these are clear and you are still getting the code the thermistor would need replaced, the resistance of the thermistor should be about 10K ohms at room temperature.

The part number for the thermistor is 35001191 and is located on the blower housing in front of the motor.

The dryer shuts off, keep getting an E1 code, what needs to be done


It sounds like this is a Whirlpool Duet or a Kenmore Elite Dryer due to the error code E1 being available only on this models. The problem here is an open thermistor as what error code E1 means. It's either the thermistor is exhibits an extremely high resistance or the wire harness connecting it to the control board is broken or cut open. Click on the link below for the detailed procedure in accessing the thermistor.

Whirlpool Duet and Kenmore Elite Electric Dryers Not Starting


Measure the resistance of the thermistor and refer the table below. Normal thermistor resistance is around 10000 ohms (10K) at room temperature.

Replace the thermistor if the resistance is significantly higher (or lower) than what it is supposed to be based on the resistance table above. Check the wire harness connecting it to the control board, if the resistance turns out good, and make sure the connectors are good and the wires are intact. Replace the wire harness if necessary. Consider replacing the control board if both the thermistor and the wire harness turn out good. The link below might enlighten you further on the troubleshooting of the thermistor.

My dryer stops and shows E1 flashing


I suggest unplugging the dryer and checking the wiring connection of the thermistor to the electronic control board. The thermistor attaches to the control board on the P2 connector (red/white and black wires on pins 5 and 6).

The image below shows the procedure for accessing the control board in this dryer (click image for zoom). If the connection is okay, pull the connector off of the control board and check the resistance through the red/white wire and black wire with a volt/ohm meter (with the dryer still unplugged). You should measure about 10K ohms (10,000 ohms) at room temperature. Make sure that your meter is set to the proper range. If you read infinite resistance (open), then you could have a wire harness connection problem between the control board and the thermistor. Check the resistance across the leads of the thermistor (with at least one wire removed from the thermistor). If you measure normal resistance (10K ohms) at the thermistor, then you will need to repair the wiring connection between the control board and the thermistor.
If you measure the proper resistance through the thermistor circuit at the connection to the control board (red/white wire to black wire on the P2 connector), then the electronic control board is bad and will need to be replaced.

T5 error code comes in my amana dryer ned 7200tw


That is actually a Ts error.

Thermistor Short Sensed

The Thermistor resistance is very low.
Check for:
- Clogged lint screen.
- Restricted vent system.
- Check Thermistor resistance.

Thermistor is Item #27 HERE
