FOR SERVICE TECHNICIAN’S USE ONLY
DO NOT REMOVE OR DES TROY
NOTE: All thermistor resistance measurements
must be made while dryer is unplugged and
connector removed from ACU.

If the resistance is OK, the outlet thermistor
is good. Proceed to step 4.

If the thermistor resistance does not agree
with the table, replace the outlet thermistor.
4. Check P14-3 and P14-6 to dryer cabinet
ground. If either pin indicates continuity
to ground (short), replace wiring harness;
otherwise, proceed to step 5.
5. If the preceding steps did not correct the
problem, replace the ACU.
Temperature Levels Incorrect – If no error code
is displayed and the connections to the thermistor
are good, check the exhaust temperature value
at any or all of the temperature levels in question,
using the Timed Dry cycle.
IMPORTANT: Be sure EcoBoost or Energy Saver
(if available) is turned OFF before testing.
1. Remove load from dryer and disconnect
external vent.
2. Plug in dryer or reconnect power.
3. Run a TIMED DRY cycle (Mixed + Timed
Dry on Whirlpool models) of at least 2 minutes
in duration and select a temperature setting
using heat.
4. Using a calibrated temperature probe,
take a temperature measurement in the center
of the exhaust outlet. The correct exhaust
temperatures are as follows:

If the temperature is not reached within
~7 minutes, check voltage level and vent
blockage, and then retest.

If the temperature probe does not agree
with temperature setting, replace the outlet
thermistor.

Inlet Thermistor
NOTE: On the electric dryer, the inlet thermistor
is part of the high thermostat assembly
(see figure 10a). On the gas dryer, the inlet
thermistor is located at the drum inlet duct
(see figure 16, page 27).
The ACU monitors the inlet temperature using
the inlet thermistor. The inlet thermistor (along
with the outlet thermistor) is used to detect air
flow, and assists in calculating load size.
1. Unplug dryer or disconnect power.
2. Remove console to access the machine
electronics.
3. Remove connector P14 from the ACU and
measure the resistance between P14-1 and
P14-2 at the connector. The following tables
(electric & gas) give temperatures and their
associated resistance values.
NOTE: All thermistor resistance measurements
must be made while dryer is unplugged and
connector removed from ACU.

If the resistance is OK, the inlet thermistor
is good. Proceed to step 4.

If the thermistor resistance does not agree
with the table, replace the inlet thermistor.
