NOTE: This test has two parts. The best test of the door switch system is done in the diagnostic mode. This
FUNCTIONAL TEST will test the door switch, wiring harness and PCB operation. If the results of this test are
normal, the door switch system and PCB response are normal. The problem is somewhere else.
FUNCTIONAL TEST (Control)
1. Enter the diagnostic mode. (See DIAGNOSTIC TEST MODE.)
2. With the door closed, press the START/PAUSE button once. The dryer will start tumbling without heat.
3. Open the door. The drum will stop tumbling. The “dE” error code should be displayed, the chime should sound seven times (if turned on), and
the drum light (if equipped) should come on. If the “dE” error code is not displayed or the light does not come on, proceed with the
MECHANICAL TEST below. If the error displays and light comes on, the door switch is working properly.
