ELECTRONIC OVEN CONTROL

ELECTRONIC OVEN CONTROL FAULT CODE DESCRIPTIONS AND RTD SCALE
Note: Only three fault codes are displayed by this control "F1", "F3", and "F9". Generally speaking "F1" implies
a control failure, "F3" an oven probe problem, and "F9" a latch motor problem. In all ocurrences the alarm is
accompanied by a display of "F1"
Fault Code
Likely Failure Condition/Cause
1. Shorted keypad.
F1
2. Control's internal checksum may
have become corrupted.
3. Control has sensed a potential
runaway oven condition. Control may
have shorted relay, RTD sensor probe
may have gone bad.
1. Open RTD sensor probe/ wiring
F3
problem. Note: EOC may initially
display an "F1", thinking a runaway
condition exists.
2. Shorted RTD sensor probe / wiring
problem. Note: "F3" is displayed
when oven is in active mode or an
attempt to enter an active mode is
made.
1. Door motor failure / jammed. Latch
F9
motor switch failure.
2. Control
component failure (relay stuck).
3. Safety thermostat opened, or cooling
fan stalled.
4. Wiring Problem.
software failure, or
Suggested Corrective Action
1. Disconnect power, wait 30 seconds and reapply power. If
fault returns upon power-up, replace EOC.
2. Check RTD sensor probe and replace if necessary. If oven
is overheating, disconnect power. If oven continues to
overheat when the power is reapplied, replace EOC.
Severe overheating may require the entire oven to be
replaced, should damage be extensive.
1. 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.
2. Check wiring in probe circuit for possible short condition.
Check RTD resistance at room temperature (compare to
probe resistance chart). If resistance does not match the
chart, replace the RTD sensor probe.
1. Press CLEAR key.
2. If CLEAR key does not eliminate problem, turn off power
for 30 seconds, then turn on power.
3. Check wiring of Lock Motor, and Lock Switch A and B, and
Door Switch circuits. Look for stalled cooling fan, broken
safety thermostat, shorts or opens.
4. Unplug Latch Motor terminal from the timer side, apply
power (L1) directly to the Lock Motor, if the motor does not
rotate, replace Lock Motor Assembly. Plug Latch Motor
terminal.
5. Check Lock Switch A, and B 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
Switches. If the Lock Switches are defective, replace Motor
Lock Assembly.
6. If all above steps fail to correct situation, replace control.
