Service Instructions for A11 SE and SEK Solid State Control Panels
THERMOSTAT ADJUSTMENT
The SE and SEK temperature controllers use solid state components and NEVER needs calibration as long as the
control is operating properly.
FAULT DIAGNOSIS
Six failure modes are provided to aid in trouble shooting oven malfunctions and to inform the user of problems.
Each failure has an associated code number that is displayed when the failure occurs. Except for the "No 50/60
Hz" error, the control also sounds a serie s of attention tones. The control must be powered down to clear the
failure mode. Below are a list of the failure codes and their meanings:
Fl — RAO low when not cooking
F2 — Actual temp-T-SET MAX +60° +49°
F3 — Open temp sensor
F4 — Shorted temp sensor
F5 — RAO high when cooking
F6 — No 50/60 Hz
UPO MODE
A user offset preference mode (UPO) is provided for users who feel that their oven cooks too hot or too cold. This
mode can be used to adjust the oven controlling temperature by + or - 49°F in 1 T increments. This adjustment
affects the entire cooking range of the oven. The UPO mode is always set in T increments, even if the oven is
in
the °C mode — the user must convert the desired °C value to T.
Access:
1. Set the Time digits of the control to 00:00.
2. Set the Cook temperature to "xl0°" (where "x" stands for any number).
3. Push and hold the Start/Timer key for 5 seconds.
Operation:
1. Either rotary dial is turned until the desired offset is displayed.
2. Pushing the actual Temp key will cause the control to exit UPO mode.
FARENHEIT / CELSIUS CHANGING
Access:
This function is accessed the same as the UPO mode except that the Cook temperature must be set to "x20°".
Operation:
1.
Each time this mode is accessed, the control flips to the opposit state that it was in before entry.
The control displays "FFF" or "CCC" to indicate the mode that the control was changed to.
Pushing the actual Temp key will cause the control to exit this mode.
2.
Each time this operation is performed, the user program area in memory is cleared to prevent
out of range programs to be used.
TIMER RESOLUTION CHANGING
Access:
This function is accessed the same as the UPO mode except that the Cook temperature must be set to "x30°".
Operation:
1.
Each time this mode is accessed, the control flips to the opposit state that it was in before entry.
The control flashes the appropriate annunciator (HR or MN) to indicate the mode changed to.
Pushing the "Actual Temp" key will cause the control to exit this mode.
NOTE: If either the timer resolution or the °C / °F change modes are performed, all user
programs and UPO values are cleared from memory.
