Troubleshooting - Extended Specific Errors and Issues The advanced diagnostic capabilities of the electronic controls utilized on the 1, 3, and 5 Class units allow for easy and thorough troubleshooting. Navigation of the control is the key and is explained in the CONTROL OPERATION section of the manual, along with control button layout, control function descriptions, a service mode menu and service menu selection explanations.
Power Fault If the unit does not (or seems to not) power on, follow the flow chart below to help diagnose the issue.
Concern Potential Causes Action No Display or Interior Lights Unit may be in Sabbath mode No Interior Light Light may be set to OFF Check LED strip for power Defective door switch Use component testing in service mode and test light circuit, manually test door switch Condensation on exterior of unit Is unit exposed to high humidity or high ambient temps? Moisture will dissipate as ambient temp. and humidity levels fall. Keep exterior of unit well polished to protect surface.
Plunger Switch Fig. 42 A plunger switch is used to monitor door state. When the door is closed it comes into contact with the plunger which closes a circuit which turns the light and display off. When the door is open the plunger moves outward and opens the circuit. If the door is left open for longer than 5 minutes the switch will trigger an error code and set an audiblewarning. Error Codes *All errors are logged in memory. *Only door error is displayed on the display and has an audible signal.
Service Mode/Self Diagnostics Note: To enter Service Mode press and hold the hidden button behind Follett for 10 seconds on user interface. After 5 minutes of non-use system will exit Service Mode.
