H = HIGH LIMIT - If “H” is present, the high limit is good.
If “-” shows then the high limit is tripped out (overheated) ordisconnected.
D = DRAIN SWITCH - If “D” is present, the drain handle (when applicable) is closed. If “-” shows then the drain is open or the switch is faulty.
E = ELEMENT SWITCH - If “E” is present, the element switch is good. If “-” shows in the display, the element is in the upright position, or the switch is faulty.
Press the right arrow button and an underscore (“_”) indicates the input is not presently detected. A Checkmark (“√” ) indicates the signal is detecting a normal input. A blinking (“X”) indicates the signal is presently detected, but is detected as a half-wave (partially failed) input.
The H, D, E signals above are wired in series. The first signal missing out of this sequence l generally causes all signals to the right of it to be missing as well.

An “AIF √ ” means normal communications between the AIF PCB and the control PCB. “AIF X” means a problem with the communications between the PCBs.
Press the Down arrow button and “FILR IN” and “USE BY 1(ex)” displays. These displays shows which controls are using the filtering system.
“USE BY 0” = not in use
“USE BY 7” = used by AIF
“USE BY 1 to 5” = used by control PCB
Press the Down arrow button and “CPU POSN” and “1 OF 3(ex)” displays. These displays shows which controls are plugged into which port on the AIF board.
For example, the left control should be plugged into port 1, and on a 3 control fryer, shows “1 OF 3” on the display.
If the right control is unplugged, then the left control would show
“1 OF 2” instead of “1 OF 3”.
Press the Down arrow button and “INP E_P_” and “JL_R_DT_” displays.
