DIAGNOSTICS & TROUBLESHOOTING
Troubleshooting WiFi Module
Perform this procedure if the appliance is not connecng to
the home area network.
1. Check Connecvity—Ask the customer to perform the
steps to connect the appliance to the wireless router of
their Home Area Network (HAN).
2. Aer the connecvity process, does the appliance connect
to the wireless router? (WiFi icon is on steady.)
¾ If yes, the WiFi Module is good.
¾ No, proceed to step 3.
3. Unplug appliance or disconnect power.
4. Access the WiFi Module. NOTE: Locaon may vary
depending on product.
5. Check Connecons—Conrm that all connecons to the
WiFi Module are securely installed, including WIDE/WIN,
and if applicable, the Front & Rear Antennas. Refer to
Figures 6 and 7 (page 4-16) to reference connecons.
6. Check DC Voltage—Set a voltmeter to DC and connect the
red lead to J4-1 and the black lead to J4-6.
7. Plug in appliance or reconnect power. Verify that 5 VDC*
is present across connector J4, pins 1 and 6.
¾ If 5 VDC*is present, proceed to step 8.
¾ If 5 VDC* is not present, check the connuity of the
harness between the WiFi Module and Control. If
harness checks good, verify 5 VDC* at the Control
board. Repair or replace as needed.
Troubleshoong the WiFi Module
*NOTE: Voltage can be higher depending on system and
WiFi module. Check appliance tech sheet.
8. Check WiFi Status LED—Locate the WiFi Status
LED window as shown in Figure 5. Repeat the WiFi
connecvity process as stated in Step 1. During the
connecvity process, does the WiFi Status LED blink fast?

¾ If yes, the WiFi processor module is good. (Refer to LED
chart on following page.)
¾ If no, replace the WiFi module. IMPORTANT: See
“Board Replacement Procedures” on page 4-13 for
instrucons on replacing the WiFi Module.
Voltage Measurement Safety Information
When performing live voltage measurements, you must do the following:
n Verify the controls are in the off position so that the appliance does not start when energized.
n Allow enough space to perform the voltage measurements without obstructions.
n Keep other people a safe distance away from the appliance to prevent potential injury.
n Always use the proper testing equipment.
n After voltage measurements, always disconnect power before servicing.
WARNING
Electrical Shock Hazard
Disconnect power before servicing.
Failure to do so can result in death or
electrical shock.
Replace all parts and panels before operating.
DANGER
Electrical Shock Hazard
Only authorized technicians should perform
diagnostic voltage measurements.
After performing voltage measurements,
disconnect power before servicing.
Failure to follow these instructions can result in
death or electrical shock.
