ERC III ELECTRONIC OVEN CONTROL FAULT CODES (continued)
FAULT
CODE
LIKELY FAILURE CONDITION/CAUSE
F1
Control software failure, or component failure (relay
stuck).
Safety thermostat opened, or cooling fan stalled.
Wiring Problem.
F3
Open RTD sensor probe/wiring problem (more than 15
seconds).
Notes: - EOC may initially display an "FI", thinking a
runaway condition exists.
- An open sensor is above 3000 ohms.
- A shorted sensor is below 700 ohms.
Shorted RTD sensor probe/wiring problem (more than
15 seconds).
Note: - "F3" is displayed when oven is in active mode
or when an attempt to enter an active mode
is made.
RTD SCALE
SUGGESTED CORRECTIVE ACTION
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 A and B
and Door Switch circuits. Look for stalled cooling fan,
broken safety thermostat, shorts or opens.
Unplug J1, apply power (L1) directly to the Lock Motor;
in the motor does not rotate, replace Lock Motor
Assembly. Plug J1.
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 LockSwitches are defective, replace
Motor Lock Assembly.
If all above steps fail to correct situation, replace control.
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.
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.
