Look for broken or loose wires, failed terminals, or wires not pressed into connectors far plenty.  IMPORTANT Electrostatic Discharge (ESD) Sensitive Electronics  ■ The most common cause for command  failure is corrosion on connectors. Therefore, disconnecting and reconnecting wires will be necessary throughout test procedures.  Do not open parcel until information technology is time to install the electronic board. ESD bug are present everywhere. ESD may damage or weaken the electronic board. The new board may appear to work well later repair is finished, but failure may occur at a later appointment due to ESD stress. ■  ■  ■  ■  Use an anti-static wrist strap. Connect wrist strap to green ground connectedness point or unpainted metal in the appliance -ORTouch your finger repeatedly to a light-green ground connexion signal or unpainted metal in the appliance. Before removing the office from its parcel, touch the anti-static purse to a green ground connection indicate or unpainted metal in the appliance.  ■ Connectors: Look at meridian of connector.  Bank check for broken or loose wires. Check for wires not pressed into connector far enough to engage metal barbs. ■ Resistance checks of components  must be fabricated with power cord unplugged from outlet, and with wiring harness or connectors asunder.  DAMP DRY TEST Begin with a fully assembled, empty dryer with make clean lint screen. Be sure dryer is connected to a known good ability source.  DIAGNOSTIC Test This test allows manufactory/service personnel to test and verify all inputs to the electronic control. The basic operation of this test is to notify the operator with an audible beep every time the status of an input to the command changes state. This test is performed with a fully assembled dryer, connected to a known good power source.  Activating the Test Mode 1. Ready the post-obit configuration: ■  Door - must exist open  ■  Signal switch - HIGH  ■  Timer - TIMED DRY or AUTO MOISTURE SENSING PLUS option  2. Turn the Fabric Care Temperature switch from AIR FLUFF to ULTRA DELICATE 3 times within a five second period. A single beep, a suspension, and then a double beep will audio to indicate that the test manner is activated. NOTE: If any of these initial weather are not satisfied, the command will not enter the test mode.  Test Fashion Functionality When the command is in examination mode, every input modify of state will outcome in an audible beep (with the exception of the Indicate switch). This includes: ■  Door switch  ■  Moisture Sensor (brusque/open up Sensor will event in a beep) Annotation: A moistened finger or damp cloth may besides be used.  ■  Fabric Care Temperature switch  ■  Push button To First (PTS) switch (with the door switch airtight)  ■  Timer (any cam input change will result in a beep) Note: Timer volition advance during test.  1. Set up the following configuration: ■  Door - must be closed  Avert touching electronic parts or concluding contacts; handle electronic lath by edges only.  ■  Timer - DAMP Dry out  ■  Fabric Care Temperature switch COTTON / TOWELS HIGH  When repackaging failed electronic board in anti-static bag, detect above instructions.  ■  Signal switch - HIGH  2. Press the PTS (Button To Start) switch. Afterwards approximately 16 seconds, the Timer will commencement to advance to the OFF position. If this role does not occur, proceed to the Diagnostic Exam.  FOR SERVICE TECHNICIAN'Southward USE But  If whatsoever of the inputs do not result in a beep, keep to the corresponding component tests on page 4.

With an ohmmeter, check for continuity betwixt the L1 terminal of the plug (institute in footstep iv) and BK (blackness wire) final on the timer. ➔ If there is continuity, go to step seven. ➔ If there is no continuity, check that wires to the concluding block are mechanically secure. If so, supplant or repair the main wire harness and exam the dryer. seven. Check for continuity betwixt the neutral (North) terminal of the plug and P2-ane (white wire) on the electronic control. ➔ If there is continuity, go to the Timer Test. ➔ If there is no continuity and the mechanical connections of the wire are secure, supersede or repair the main wire harness.  3. Measure resistance between the motor relay common (COM) terminal and ground. A high resistance (open up) should be measured. ➔ If it does not, perform the Thermal Fuse, Door Switch and Belt Switch Tests and check harness continuity. If they exam good, replace the motor.  2. Bank check door switch continuity. Neutral to P2-6 on the electronic control should read closed with the door closed, and open with the door open. 3. Otherwise, verify harness continuity. ➔ If no continuity, repair or replace the harness. ➔ If harness is good, replace the door switch.  Orange  i. Disconnect dryer from power. 2. Disconnect belt switch from harness and check chugalug switch continuity.  Perform the diagnostic test on page 1 to determine that the timer motor advances (should run continuously). If the timer does not advance or fails the diagnostic test:  ➔ With the belt switch in the proper run position, information technology should measure closed (motor test measurement tin be done to verify the belt switch). Run across illustration below. Belt Switch Pulley  1. Disconnect dryer from ability. 3. Bank check the timer motor impedance and timer switching.
