Knowing which wire goes to what is required. Then you may ohm it out changing the switches position. when the door closes then one set of contacts are opened and the other set is closed. Best described as one hot to a parallel switch. One allows the the light to come on and the other is a permissible circuit loop that will allow the unit to function when the door is closed. :?)

Whirlpool Dryer Various Test Procedures - Part 3


TEST #5 Moisture Sensor
NOTE: This test is started with the machine completely assembled.This test is performed when an automatic cycle
stops too soon, or runs much longer than expected. NOTE: Dryer will shut down automatically after 2-1/2 hours.
The following items are part of this system: Harness/connection, Metal sensor strips, Machine control electronics
1. Activate the diagnostic test mode and advance past saved fault codes.
2. Open the dryer door. If a continuous beep tone is heard and an alphanumeric number is displayed on the console as soon as the door is opened, a short circuit exists in the moisture sensor system. If this doesn’t happen, go to step 3. Otherwise, go to step 4. NOTE: Over drying may be caused by a short circuit in the sensor system.
3. Locate the two metal sensor strips on the inside of the dryer. Bridge these strips with a wet cloth or finger.
If a continuous beep tone is heard and a software revision number is displayed on the console, the sensor passes the test. Go to step 8. If not, continue with step 4.
4. Access the moisture sensor wires: Remove the lint screen. Remove the two wires holding the lint screen to the top. Remove the four screws from bottom of the duct in rear. Remove the duct from the dryer to access
the moisture sensor.Disconnect the sensor connector.
5. Access the machine control electronics. Remove the connector P13 from the circuit board. Check the main
harness connections between the sensor connector and machine control for a short or open circuit. Replace the main harness if necessary. If the harness is okay, continue with step 6.
6. Measure the resistance across the outermost contacts of the sensor connector that includes the two MOVs. Sensor Harness with MOVs (Metal Oxide Varistors) Sensor Connector Sensor Blower Housing Disconnect sensor connector. If a small resistance is measured, check for debris across moisture strips inside of the drum; clean if debris is present. If debris is not present, replace sensor harness with MOVs. Otherwise go to step 7.
7. Measure the resistance across each of the outermost contacts and the center terminal (ground connection).
If a resistance less than infinity is measured, replace the sensor harness with MOVs.
8. If moisture sensor diagnostic test passes, check the thermistor: Perform TEST #4a. If the problem persists after replacing the moisture sensor, harness with MOVs and thermistor, replace the machine control electronics.

TEST #6 Buttons and Indicators
This test is performed when any of the following situations occurs during the Console Buttons and Indicators Diagnostic Test:
None of the indicators light up No beep sound is heard
Some buttons do not light indicators None of the indicators light up:

1. See Diagnostic Guide/Before Servicing.
2. Perform TEST #1 to verify supply connections.
3. Perform TEST #2.
4. Visually check that the P5 connector is inserted all the way into the machine control electronics.
5. Visually check the user interface assembly connections.
6. If both visual checks pass, replace the user interface assembly.
7. Plug in dryer or reconnect power.
8. Perform the Console Buttons and Indicators Diagnostic test to verify repair.
9. If indicators still do not light, the machine control electronics has failed: Unplug dryer or disconnect power.
Replace the machine control electronics. Plug in dryer or reconnect power. Perform the Console Buttons and Indicators Diagnostic test to verify repair.
No beep sound is heard:
1. Visually check that the P5 connector is inserted all the way into the machine control electronics. If visual check passes, replace the user interface assembly.
2. Plug in dryer or reconnect power.
3. Perform the Console Buttons and Indicators Diagnostic test to verify repair.
4. If replacing the user interface assembly failed: Unplug dryer or disconnect power. Replace the machine control electronics. Plug in dryer or reconnect power. Perform the Console Buttons and Indicators Diagnostic test to verify repair.
Some buttons do not light indicators:
1. Visually check the user interface assembly connections. If visual check passes, replace the user interface assembly.
2. Plug in dryer or reconnect power.
3. Perform the Console Buttons and Indicators Diagnostics test to verify repair.

TEST #7 Door Switch
Activate the diagnostic test mode and perform the Door Switch Diagnostic test.
Functionality is verified with a beep each time the door is closed and opened, and a number and letter appears in the display (i.e., 0E, 09). If any of the above conditions are not met: Unplug dryer or disconnect power.
Check that the wires between the door switch and machine control electronics are connected. If the connections are OK, replace the door switch assembly and retest. If the door switch assembly has been replaced and dryer still does not start, replace the machine control electronics.

Whirlpool Dryer Various Test Procedures - Part 1


TEST #1 Supply Connections
This test should only be done after confirming proper voltage at the outlet.
1. Unplug dryer or disconnect power.
2. Remove the cover plate from the back of the dryer.
3. Check that the power cord is firmly connected to the dryer’s wire harness.
4. Access the machine control electronics without disconnecting any wiring to the control board.
5. With an ohmmeter, check for continuity between the neutral (N) terminal of the plug and P8-3 (white wire) on the machine control board. If there is continuity, go to step 6. If there is no continuity, disconnect the white wire of the harness from the power cord. Test the continuity of the power cord neutral wire . If an open circuit is found,
replace the power cord. Otherwise, go to step 6.
6. In a similar way, check the continuity between the L1 terminal of the plug and P9- 2 (black wire) on the control board. If there is continuity, go to step 8. If there is no continuity, check the continuity of the power cord for power cord’s L1 wire. If an open circuit is found, replace the power cord. Otherwise, go to step 7.
7. Replace the main harness.
8. Visually check that the P5 connector is inserted all the way into the machine control electronics.
9. Visually check that the user interface assembly is properly inserted into the front console.
10. If both visual checks pass, replace the user interface assembly.
11. Plug in dryer or reconnect power.
12. Perform the Console Buttons and Indicators Diagnostic test to verify repair.
13. If indicators still do not light, the machine control electronics has failed: Unplug dryer or disconnect power.
Replace the machine control electronics. Plug in dryer or reconnect power. Perform the Console Buttons and Indicators Diagnostic test to verify repair.

TEST #2 Machine Control Power Check
This test is used to determine if power is present at the machine control electronics.
NOTE: The drum light is controlled by the machine control on all models.
1. Plug in dryer or reconnect power.
2. Open the door.If the drum light illuminates, then power is present at the machine control, and it is functional. Go to TEST #6. If the drum light fails to illuminate, do not assume the machine control electronics needs replacement. Several conditions may cause the drum light not to illuminate, including a bad bulb. If the drum light does not illuminate, go to TEST #1.

TEST #3 Drive Motor Circuit
This test will check the wiring to the motor and the motor itself. The following items are part of this motor system:
Harness/connection Belt/belt switch Drive motor Centrifugal switch Door switch Machine control electronics
1. Unplug dryer or disconnect power.
2. Access the machine control electronics and measure the resistance across P8-4 and P9-1.
If resistance across P8-4 and P9-1 is in the range of 1 to 6 ohms, replace the machine control electronics.
Otherwise, go to step 3.
3. Check the wiring and components in the path between these measurement points by referring to the appropriate wiring diagram and strip circuit in Section 7.
4. Check the belt switch and drive motor. Access the belt switch and drive motor by removing the front panel/drum assembly. Slowly remove the drum belt from the spring-loaded belt switch tension pulley, gently letting the belt pulley down.
5. Remove the white connector from the drive motor switch.
6. Check for the resistance values of the motor’s Main and Start winding coils. NOTE: Main and Start winding coils must be checked at the motor.WINDING RESISTANCE ω CONTACT POINTS OF MEASUREMENT
MAIN 1.4–2.6 Blue wire in back at pin 4 and bare copper wire on pin 5 of black drive motor switch
START 1.4–2.8 Blue wire in back at pin 4 and bare copper wire on pin 3 of black drive motor switch. If the resistance at the motor is correct, there is an open circuit between the motor and machine control electronics.
Check for failed belt switch. If the Start winding resistance is much greater than 4 ohms, replace the motor.
7. Check the belt switch by measuring resistance between the two blue wires while pushing up the belt switch tension pulley.If the resistance reading goes from infinity to a few ohms as pulley arm closes the switch, belt switch is OK. If not, replace the belt switch. If belt switch is OK and there is still an open circuit, check and repair the wiring harness.
8. Door switch problems can be uncovered in the Door Switch Diagnostic Test; however, if this was not done, the following can be done without applying power to the dryer. Connect an ohmmeter across P8-3 (neutral, white wire) and P8-4 (door, tan wire).With the door properly closed, the ohmmeter should indicate a closed circuit
(0–2 ohms). If not, replace the door switch assembly.

My dryer 66912691 will not start


start by checking the main power line to the program controller unit. Check the voltage output on the controller when the start is initiated. If absent check the door switch. If present then you can isolate the motor /motor drive and confirm the working of the motor with a bench test. If there is a capacitor start, check the value with a mains test or use one in parallel. Check the relay to the motor. Also this will confirm why the dryer does not work.

Dryer stpped working


with power disconnected
if any wire disconnected before any test, reconnect & test dryer, reconnect wires after each test
disconnect wires from start button and test, conduct when pushed, no conduct when release
if fail replace start button test dryer
disconnect wires from door switch and test, conduct when pushed, no conduct when release
if fail replace door switch test dryer
follow leads from start button to relay(relay is first device connected to start button), and make sure all wires connected at both ends. If any wires disconnected, test dryer
locate thermostats and thermal fuses on fan housing and ducts
individually disconnect wires from each and test. conduct good, no conduct fail
replace any failed thermal fuse or thermostat test dryer
if all prior test OK
replace relay, test dryer

Moisture Sensor Location


It could be the sensor. However, check the exhaust vent for restrictions first. you can test the moisture sensor Damp Dry Test 1. Set the following Timer- DAMP DRY Fabric Care/Temperature switch- COTTON HIGH Wrinkle Guard switch- OFF Signal switch- LOUD Door- must be closed 2. Press the PUSH TO START switch. After approximately 16 seconds, the Timer will start to advance to the OFF position, and the ?End of Cycle? signal will sound. If one or more of these functions do not occur, proceed to the Factory Test. Factory Test The Factory Test allows factory/service personnel to test and verify all inputs to the Even Heat 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 control changes state. Activating the Test Mode 1. Set the following configuration: Door- must be open Fabric Care/Temperature switch- AIR FLUFF Signal switch- LOUD Timer- TIMED DRY OR AUTO MOISTURE SESING PLUS selection 2. Turn the Wrinkle Guard switch from OFF to ON three times within a five second period. A single beep will sound to indicate that the factory test mode is activated. NOTE: If any of these initial conditions are not satisfied, the control will not enter the test mode. Test Mode Functionality When the control is in the Factory Test mode, every input change of state will result in a beep (with the exception of the Signal switch). This includes: Door switch Moisture Sensor (short/open Sensor will result in a beep) NOTE: A moistened finger or damp cloth may also be used. Fabric Care/ Temperature switch Wrinkle Guard switch Push to Start (PTS) switch (with the door switch closed) Timer (any cam input change will result in a beep) NOTE: Timer will advance during test. If any of the inputs do not result in a beep, proceed to the following component tests If the dryer shuts off too soon when set to the AUTO MOISTURE SENSING PLUS cycle, check the following: -HARNESS/CONNECTION -MOISTURE SENSOR -THERMISTOR -EVEN HEAT CONTROL Procedure: 1. Test the Moisture Sensor by following the procedure outlined in ?Factory Test?, beginning on page 3. If the Moisture sensor fails the ?Factory Test? (does not produce a beep sound), check the Moisture Sensor. a. If there is continuity to Ground for Yellow/Red (Y/R) wire with no load, look for a short in the Sensor or Y/R wire. Verify harness connections both at the Sensor and the Even Heat control. b. If the Sensor and Y/R wire are good, replace the Even Heat control. 2. If Factory Test passed, verify thermistor by performing test procedures outlined in ?Thermistor Test? 3. If problem persists after replacing Moisture Sensor and thermistor
