ELECTRONIC OVEN CONTROL (FAULT CODES)
ELECTRONIC OVEN CONTROL (EOC) FAULT CODE DESCRIPTIONS
Note: Only four fault codes series are displayed by this control "F1", "F2", "F3" and "F9". Generally speaking "F1" implies
a control failure, "F2" a bad communication between display board and relay board, "F3" an oven probe problem, and "F9"
a latch motor problem.
Fault Code
Likely Failure Condition/Cause
Series
(F10) Control has sensed a potential
F1
runaway oven condition. Control
may have shorted relay, RTD sensor
probe may have a gone bad.
(F11) Shorted Key: a key has been
detected as pressed (for more than
the debounce period) will be
considered a shorted key alarm
and will terminate all oven activity.
(F13) Control's internal checksum may
have become corrupted.
(F14) Relay watchdog failure.
(F20) Bad communication between
F2
display board and relay board.
F3
(F30) Open RTD sensor probe/ wiring
problem. Note: EOC may initially
display an "F10", thinking a
runaway condition exists.
(F31) Shorted RTD sensor probe / wiring
problem. Note: "F31" is displayed
when oven is in active mode or an
attempt to enter an active mode is
made.
(F32) Key loop is detected as an open
cicuit.
F9
(F90 Door motor mechanism failure.
and
F95)
Suggested Corrective Action
Press Clear or Cancel key.
Check RTD sensor probe and replace if necessary. If oven is
overheating, disconnect power. If oven continues to oveheat
when power is reapplied, replace EOC. Severe overheating may
require the entire oven to be replaced, should damage be
extensive.
Press Clear or Cancel key.
Press Clear or Cancel key.
Disconnect power, wait 30 seconds ad reapply power. If fault
returns upon power-up, replace EOC.
Press Clear or Cancel key.
Replace Relay board.
Press Clear or Cancel key.
Verify connections between 2 boards (P1 and J1).
Press Clear or Cancel key.
Check wiring in probe circuit for possible open condition.
Check RTD resistance at room temperature (compare to probe
resistance chart). If resistance does not match the chart, replace
the RTD sensor probe.
Let the oven cool down and restart the function
Press Clear or Cancel key.
Verify if the the keyboard is connected (P3).
Press CLEAR key.
If CLEAR key does not eliminate problem, turn off power for
30 seconds, then turn on power.
Check wiring of Lock Motor, and Lock Switch and Door Switch
circuits.
Unplug the lock motor from the board and apply power (L1)
directly to the Lock Motor. If the motor does not rotate, replace
Lock Motor Assembly.
Check Lock Switch A for proper operation (do they open and
close, check with ohmmeter). The Lock Motor may be powered
as in above step to open and close Lock Switch. If the Lock
Switch is defective, replace Motor Lock Assembly.
If all above steps fail to correct situation, replace EOC.
