DIAGNOSTIC FAULT CODE STORAGE AND
RETRIEVAL
The control in this furnace is equipped with memory that stores up to
five error codes to allow a service technician to diagnose problems
more easily. This memory is retained even if power to the furnace is
lost.
This feature must only be used by a qualified service techni-
cian.
If more than five error codes have occurred since the last reset, only the
five most recent error codes are retained. The furnace control board
has a button labeled LAST ERROR that is used to retrieve error codes.
This function only works if there are no active thermostat signals, so
any call for heating, cooling, or continuous fan must be terminated
before attempting to retrieve error codes.
To retrieve the error codes, press the LAST ERROR button. The LED
on the control flashes the error codes that are in memory, starting with
the most recent. There is a two-second pause between each flash
code. When the error codes have all been displayed, the LED resumes
the normal slow green flash after a five-second pause. To repeat the
series of error codes, push the button again.
If there are no error codes in memory, the LED flashes two green
flashes. To clear the memory, press the LAST ERROR button and hold
it for more than five seconds. The LED flashes three green flashes
when the memory has been cleared, and resumes the normal slow
green flash after a five-second pause.
