ERC FAULT CODE MEMORY DISPLAY
Have you ever run a service call and been told by the consumer
that their range displayed an "F" fault code and when you arrive
the fault is gone (cleared by the consumer) and the consumer
can not remember what the code was?
Well there is now a way to "recall" the last four fault codes from
the ERC memory. Care must be taken in interpreting these
codes because once you determine the cause of the fault code,
there is no way to clear the code(s) from the ERC memory. In
other words, the history that you are looking at in the display
could be a weeks worth of history, or 5 years - there is no way to
tell. With this in mind, the last fault code stored in memory is the
one that you should focus on, because the others may have
occured a long time prior to the last one.
HOW TO DISPLAY THE FAULT CODES IN MEMORY
To read the fault code memory, follow the steps below:
1.
Simultaneously press the COOKING TIME, DELAY START
and number 9 pads. A history of the last four fault codes
will appear in the display. NOTE: If no keypad entry is
made within 5 minutes, the ERC test mode will "time out".
2.
To terminate the memory fault mode press the CLEAR /
OFF key pad
HOW FAULT CODES ARE STORED IN MEMORY - EXAMPLE
A
If we displayed the fault code memory for a new range, one
that has never experienced a fault code, we would see four zero's
in the display, meaning that no fault codes are stored in memory.
B
The first time a fault code occurs, the ERC display will store
the fault code in it's memory. When you read the fault code ,
which is stored in memory, the code will display in the far right
hand digit of the clock display.
C
If a second fault code occurs, it too is stored in the ERC
memory. The first fault code stored in memory scrolls to the left,
and the new fault code now displays in the far right hand digit of
the clock display.
D
If the same fault code repeats itself (sequencially), without
being separated by a different fault code, then the repeated fault
code will "stack" in memory. In other words, the repeated fault
code will only display once, unless separated by a different fault
code. In this example, F3 repeats itself twice, the resulti n g fault
code memory display only shows one 3. The same would also
be true if F3 repeated itself four times, the result showing in the
fault code memory display would be one "3", NOT four "3"'s.
E
If a fourth fault code occurs, the ERC will scroll the previous
fault codes stored in memory to the left, one digit, and store the
new fault code in the far right hand digit of the clock display.
F
If a fifth fault code occurs, the ERC will continue to scroll the
previous fault codes to the left, and store the new fault code in
the far right hand digit of the clock display.
G
If a sixth fault code occurs, the ERC will once again scroll the
previous fault codes to the left. Notice in this example the first
fault code (F1), previously stored in memory is now lost. The
ERC will continue to scroll the previous fault codes to the left and
store the new fault code in the far right hand digit of the clock
display.
