Testing the Dryer

Once you have completed the installation of the appliance, use this test to make sure the condition of the exhaust system is adequate for proper operation of the appliance. This test should be performed to alert you to any serious problems in the exhaust system of your home.

Testing Dryer Heating

Gas Models

Close the dryer door and press the Power button to turn the dryer on. Select the Timed Dry and Start/Pause buttons to start the test. When the dryer starts, the igniter should ignite the main burner.

Note

  • If all air is not purged from the gas line, the gas igniter may turn off before the main burner ignites. If this happens, the igniter will reattempt gas ignition after approximately two minutes.

Electric Models

Close the dryer door and press the Power button to turn the dryer on. Select the Timed Dry and Start/Pause buttons to start the test. The exhaust air should be warm after the dryer has been operating for 3 minutes.

Checking Airflow

Effective dryer operation requires proper airflow. The adequacy of the airflow can be measured by evaluating the static pressure. Static pressure in the exhaust duct can be measured with a manometer, placed on the exhaust duct approximately 2 ft. (60.9 cm) from the dryer. Static pressure in the exhaust duct should not exceed 0.6 inch (1.5 cm). The dryer should be checked while the dryer is running with no load.

Activating the Installation Test

Note

  • The appliance should be cool before starting this test. If the appliance was warmed up during installation, run the Air Dry cycle for a few minutes to reduce the interior temperature.

  • Before starting the test, please check that the voltage is 230V±6%. If the voltage is less than 225V, a duct clogging error may occur even though the duct is not actually clogged (electric model only).

  • Do not load anything in the drum for this test, as it may affect the accuracy of the results.

  • Press the Power button and touch the upper left corner of the display 10 times slowly. And then select Dryer after selecting Install Mode.

    • This button sequence activates the installation test. A message will display if the activation is successful.

  • Press the Start/Pause button.

    • The appliance will start the test, which will last a few minutes. The heat will be turned on and the temperatures in the drum will be measured.

  • Check the display for results.

    • During the test cycle, monitor the error messages displayed on the control panel. If the duct blockage message has not been displayed when the cycle ends, the exhaust system is adequate. If the exhaust system is severely restricted, the duct blockage message will be displayed. Other problems may also be shown with error messages. See the chart on the next page for error code details and solutions.

    • If the duct blockage displays that the exhaust system is severely restricted, have the system checked immediately, as performance will be poor.

  • End of cycle.

    • At the end of the test cycle, a message will display. The test cycle will end and the appliance will shut off automatically after a short delay.

Check the Duct Condition

If the duct blockage message is displayed,, check the exhaust system for restrictions and damage. Repair or replace the exhaust system as needed.

Note

  • When the appliance is first installed, this test should be performed to alert you to any existing problems with the exhaust duct in your home. However, since the test performed during normal operation provides more accurate information on the condition of the exhaust duct than the installation test, the percentage of blockage displayed during the two tests may not be the same.

  • Do not interrupt the test cycle, as this could result in inaccurate results.

  • Even if no duct blockage message is displayed during the test cycle, some restrictions may still be present in the exhaust system. Refer to the Venting the Dryer section of this manual for complete exhaust system and venting requirements.

Error Codes

Check the error code before you call for service.

Error Messages

Possible Cause & Solution

Temp Sensor Error 1

Temperature sensor failure.

  • Turn off the appliance and call for service.

Humidity Sensor Error

Humidity sensor failure.

  • Turn off the appliance and call for service.

Power Supply / High Voltage / Low Voltage

Electric dryer power cord is not connected correctly, or house power supply is incorrect.

  • Reset circuit breaker or replace fuse. Do not increase the fuse capacity.

House fuse is blown, circuit breaker has tripped, or power outage has occurred.

  • If the problem is a circuit overload, have it corrected by a qualified electrician.

Gas Supply

Gas supply or service turned off. (Gas Model only.)

  • Confirm that house gas shutoff and the dryer gas shutoff are both fully open.

Duct Blockage (80%) / Duct Blockage (90%) / Duct Blockage (95%)

Exhaust system is too long or has too many turns/restrictions.

  • Do not use the appliance until the exhaust system has been cleaned and/or repaired. Using the appliance with severely restricted exhaust is dangerous and could result in a fire or other property damage.

  • Check the outside dryer vent while the appliance is operating to make sure there is strong airflow. If the exhaust system is extremely long, have it repaired or rerouted.

Door Open

Door open error.

  • Do not open the door when doing installation mode. Restart Installation mode.

Restricted or Blocked Airflow

Avoid long runs or runs with multiple elbows or bends.

Excess or crushed transition duct
Too many elbows or exhaust too long
Check for blockages and lint buildup.
Make sure the ductwork is not crushed or restricted.
