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 a way to "recall" the last four fault codes from the

ERC memory. These codes are stored in short term memory

(RAM) and can be recalled by the service Technician; however, it

is important to note that once power is lost to the appliance

the memory (RAM) is cleared and "reset" to all eights. When

servicing a range for a fault code problem, always remove power

to the unit. This will protect you from electrical hazards and will

also reset the fault code memory storage back to all eights.

HOW TO DISPLAY THE FAULT CODES IN MEMORY

To read the fault code memory, follow the steps below:

Simultaneously press and hold the COOKING TIME and

DELAY START pads. While holding these two pads press

the number 9 pad. 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".

To terminate the memory fault mode press the CLEAR /

OFF key pad

HOW FAULT CODES ARE STORED IN MEMORY - EXAMPLE

If we displayed the fault code memory of the range just after

power had been applied/reapplied, we would see four eights in

the display, meaning that no fault codes are stored in memory.

The first time a fault code occurs, the ERC display will store

the fault code in its 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.

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.

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 resulting 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.

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.

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.

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.
