E1 or E2
Thermistor Failure
The dryer
will not operate if the exhaust temperature drops below 18 degrees F.
or exceeds 250 degrees F.
When the thermistor circuit is open (>50K ohms), the error code E1 flashes
in the display.
When the thermistor circuit is shorted (<500 ohms), the error code E2
flashes in the display.
Normal thermistor resistance values:
60 degrees F. - 15.3K ohms.
70 degrees F. - 11.9K ohms.
80 degrees F. - 9.2K ohms.
Take the top off the dryer and inside you'll find the "tech sheet." It has
instructions for removing the front panel and locating the thermistor.
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 End Of Cycle Signal (Louder)
? Press 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 & Removing the Electronic
Assemblies, page 7, and figure 8 for
thermistor location.
? If wire connections are good, remove the
two wires from the thermistor and replace
the thermistor.
the part number is 8577274 you can remove the lower panel in the front to change the part.
