TROUBLESHOOTING GUIDES
This section of the manual contains:
• The Error Code Table and the Error Code Troubleshooting Guide.
• The General Troubleshooting Guide, which covers all problems that a 700-3 Series Base unit may experience.
• The Sealed System Diagnostic Tables.
• The Membrane Switch/Ribbon Cable Test Procedures, used to determine if a control panel assembly is defective.
HOW TO USE ERROR CODE TROUBLESHOOTING GUIDE
Error Codes indicate problems registered by specific components. If error codes are registered, they will appear
before temperature readings while in Diagnostic Mode.
NOTE: If Error Codes appear with a flashing “SERVICE” indicator prior to initiating Diagnostic Mode, the unit expe-
rienced temperature problems that may or may not be associated with the Error Codes displayed.
To initiate Diagnostic Mode, press and hold either
COLDER key, then press the UNIT ON/OFF key, then release
both keys. Now, check to see if Error Codes are displayed, being sure to toggle through all error and temperature
readings by pressing either COLDER key or either WARMER key. (See Error Code Table Below)
If Error Codes appear during Diagnostic Mode, follow the Error Code Troubleshooting Guide on the following pages.
The left column lists the error codes. The right column explains what tests to perform and/or what action to take to
correct the error.
NOTE: If error codes are observed in diagnostic mode, a non-flashing SERVICE indicator will appear on the LCD
when Diagnostic Mode ends, indicating error codes are stored. Error Codes must be manually cleared from the
electronic control memory. To clear the non-flashing SERVICE indicator and the error codes, the problem must be
corrected and the unit must be ON. Then, press and hold the Door Ajar Alarm Bell ON/OFF key for 15 seconds.
The control will emit a short “beep” when the SERVICE indicator and error codes are cleared.
