EQUENCE
A. Power down heater and re-power. This is similar to rebooting a com-
puter.
B. If rebooting does not solve the problem, inspect the display interface
wiring. Ensure the display interface plug is securely attached to the
control module.
C. If steps A & B do not resolve the CE error, the control module and/or
display interface assembly are defective and must be replaced.
