Were is the Thermistor Located and is there a way to trouble shoot it to see if it is bad? Thank You
Answer It is located on the blower wheel housing assembly. You can test it with a multi-meter, it should read around 10,000 ohms at room temperature.

My dryer recently stopped heating, although the drum still worked. After reading your posts I purchased a Thermistor from you guys (fast shipping) and just installed it per your video (great tutorial). After 1 minute of running, the E2 Error code appears. Everything I read states that code means you need a new Thermistor? I have checked the connections a number of times on the newly installed part and everything looks great. Any thoughts??
You will want to test the thermistor at the control board connection to make sure that there is proper resistance. The reason to do a the control board would be so that you are testing the wires as well. At 70 degrees the thermistor should read 11.5K to 13.5K ohms. At 80 it would be between 8.5K and 10.5K ohms. Also test the exhaust thermistor as it could be faulty as well. It is possible that the wiring harness could be bad also. If all checks ok then the issue will be in the control board.
Kitchen aid Gas Dryer Model kghs02rwh0. Just installed a used Dryer, prior to thou I did install Conversion Kit to run with Propane not NG. Turned on, OK, Ignited OK, ran for about a minute (sensing) then shut off, E1 Code displayed. No wet clothes maybe, threw in few damp towels, same thing. Went from auto to manual same thing, Help
The E1 error code is a thermistor open error. The things that you will want to check is the following:
The machine control electronics monitors the exhaust temperature
using the thermistor, and cycles the heater relay on and off to
maintain the desired temperature.
Begin with an empty dryer and a clean lint screen.
1. Plug in dryer or reconnect power.
2. Set the following configuration:
? Door – must be firmly closed
? Press CONTROL ON
? Press CYCLE END SIGNAL [Loud]
? Press HOLD TO START
3. If after 60 seconds, E1 or E2 flashes in the display and the dryer
shuts off, the thermistor or wire harness is either shorted or open.
? Unplug dryer or disconnect power.
? Check wire connections at the machine control electronics
and thermistor. See Accessing the Machine Control
Electronics Assembly, page 13, and figure 9 for thermistor
? If wire connections are good, remove the two wires from the
thermistor and replace the thermistor. See figure 9.
? Plug in dryer or reconnect power
4. If E1 or E2 does not flash in the display, the connections to the
thermistor are good. Therefore, check the thermistor’s resistance
value at any or all of the temperature levels in question, using the
Timed Dry Cycle, and the following process:
Hold a glass bulb thermometer capable of reading from
32° to 82°C (90° to 180°F) in the center of the exhaust outlet. The
table at the top of the page shows correct exhaust temperatures.
5. If the exhaust temperature is not within specified limits, check the
resistance of the thermistor.
NOTE: All thermistor resistance measurements must be made
while dryer is unplugged or disconnected from power.
The top table also gives the resistance values that should be
observed for the various temperature settings.
If needed, the table at right
gives temperatures and their
associated resistance values.
? If the thermistor resistance
checks within normal limits,
replace the machine

My whirlpool dryer continues to overheat, I have checked the lint screen cleaned out the duct to the blower wheel, the wheel and up to the vent. I have replaced the heating element the hi cut off fuse, thermostat. And run a continuity test on the thermistor which continues to rise could that be the problem? If not where do I go from here?
When testing the thermistor, you will want to check at room temperature which at 77 degrees should be around 49k to 51K ohms on the inlet thermistor and 8.5k to 10.5k ohms on the exhaust thermistor. When the unit is running an you test the thermistor the resistance should go down. If the resistance is rising then the issue would be with the thermistor.
