A. Plug power cord in and verify that
the circuit breaker is not tripped.
B. If available, substitute a controller
known to be working for the
suspect controller. If the substitute
controller functions correctly, order
a new controller from a FASC.
C. If any of the components in the
power supply system (including the
component or
transformer and temperature control
board) fail, power will not be
supplied to the controller and it will
not function.
A. If available, substitute a controller
known to be working for the
suspect controller. If the substitute
