TEST #6 Door Switch
Go into the Diagnostic Test #1 mode. See
page 6-18. Functionality is verified by the ap-
pearance of an alpha numeric code in the dis-
play ("Software revision" – door closed, "GAS"
– door open etc.).
• If any of the above conditions are not met,
or if "GAS" is displayed when the door is
closed, check that the wires between the
door switch and machine control electron-
ics are connected. See Figure 2 for switch
location, and see Accessing & Removing
the Electronic Assemblies, page 6-28.
• If the connections are OK, replace the wire
and door switch assembly and retest.
• If wire and door assembly have been re-
placed and dryer still does not start, replace
the machine control electronics.
TEST #7 Lint Drawer Switch
This test will check the wiring to the lint drawer
switch and the lint drawer switch itself.
1. Unplug dryer or disconnect power.
2. Access the machine control electronics.
See Accessing & Removing the Electron-
ic Assemblies, page 6-28. Then measure
the resistance across P3-7 and P3-8.
3. Close the lint drawer and measure the
resistance. It should indicate a closed
circuit.
4. Now open the lint drawer and measure
the resistance. It should indicate an open
circuit.
• If any of the conditions are not met
check that the wires between the lint
drawer switch and machine control
electronics are properly connected.
• If the connections are OK, replace the
lint drawer switch and retest.
• If wires and lint drawer switch assem-
bly have been replaced and dryer still
does not start, then replace the ma-
chine control electronics.
TEST #8 Dry Rack Sensor
This test will check the wiring to the dry rack
sensor and the dry rack sensor itself.
1. Unplug dryer or disconnect power.
2. Access the machine control electronics.
See Accessing & Removing the Electron-
ic Assemblies, page 6-28. Then measure
the resistance across P3-11 and P3-12.
3. Insert the dry rack and measure the re-
sistance. It should indicate a closed cir-
cuit.
4. Now remove the dry rack and measure
the resistance. It should indicate an open
circuit.
• If any of the above conditions are not
met check that the wires between the
dry rack sensor and machine control
electronics are properly connected.
• If the connections are OK, replace the
dry rack sensor and retest.
• If wires and dry rack sensor have been
replaced and and error code E5 persists
or the drum will not tumble, then replace
the machine control electronics.
