IV. Service Diagnosis
WARNING
• This appliance should be diagnosed and repaired only by qualified service
personnel to reduce the risk of death, electric shock, serious injury, or fire.
• Risk of electric shock. Use extreme caution and exercise safe electrical practices.
• Moving parts (e.g., fan blade) can crush and cut. Keep hands clear.
• Make sure all food zones are clean after the appliance is serviced. For cleaning
procedures, see "VI.A. Cleaning Instructions."
A. Diagnostic Procedure
The diagnostic procedure is basically a sequence check that allows you to diagnose the
electrical system and components. Before proceeding, check for correct installation and
proper voltage per appliance nameplate. As you go through the diagnostic procedure,
check to assure the components energize and de-energize correctly. If not, those
components or controls are suspect. Always choose a neutral (W wire) to establish a
good neutral connection when checking high voltages. If the display module is in alarm,
see "II.D.2. Alarm Safeties." For further details, see "IV.B. Control Module Check." For
factory default settings, see "II.C.2.a) Default Settings."
Note: When exposed to high temperatures a high-temperature alarm "Hi" may occur
at start-up. To silence the alarm, press and release the upper button. Alarm
automatically resets when temperature drops to an acceptable range.
IMPORTANT
The maximum allowable voltage variation is ±10 percent of the nameplate rating.
115VAC is used as a reference voltage when checking voltage to components.
Voltage may vary depending on power supply.
1) Move the power switch to the "OFF" position.
2) Unplug the appliance from the electrical outlet.
3) Remove the control box cover.
4) Plug the appliance back into the electrical outlet.
5) Move the power switch to the "ON" position.
6) Confirm proper supply voltage (115VAC) to the power switch. On 3-section
appliances, also confirm proper supply voltage to the receptacle box (115VAC for
refrigerator/208-230VAC for freezer).
