B. Service Diagnosis
WARNING
• The 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.
NOTICE
• The appliance is not intended for outdoor use. Normal operating ambient
temperature must be within 45°F to 100°F (7°C to 38°C).
• The appliance must not be located next to ovens, grills, or other high heat
producing equipment.
• The appliance must not be located in a corrosive environment.
• The appliance must be a minimum of 4" (11 cm) from side walls.
• A minimum of 10" (25 cm) overhead clearance must be provided for proper
ventilation.
The diagnostic procedure is a sequence check that allows you to diagnose the electrical
system and components. Before proceeding, check for correct installation and proper
voltage per nameplate. Always choose a neutral (W) to establish a good neutral
connection when checking high voltages. If the display is in alarm, see "III.D. Alarm
Safeties."
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.
