Roper Fault Codes

Roper Oven/Range/Stove Fault Codes

Note: Depending upon the brand of appliance, there can be many different names for the 'clock' component. Electronic Range Control, ERC, Electronic Oven Control, EOC, control board, and clock all refer to the same part.

4 Digit Failure Codes

• F1-E0 - EEPROM Communication Error - Disconnect power for at least 30 seconds and then reconnect. Allow at least a minute after power has been restored and if error code reappears, replace control board (clock).
• F1-E1 - EEPROM Checksum Error - Disconnect power for at least 30 seconds and then reconnect. Allow at least a minute after power has been restored and if error code reappears, replace control board (clock).
• F1-E2 - UL A/D Error(s) - Disconnect power for at least 30 seconds and then reconnect. Allow at least a minute after power has been restored and if error code reappears, replace control board (clock).
• F1-E4 - Model ID Error - Disconnect power for at least 30 seconds and then reconnect. Allow at least a minute after power has been restored and if error code reappears, replace control board (clock).
• F1-E5 - Calibration Shifted - Disconnect power for at least 30 seconds and then reconnect. Allow at least a minute after power has been restored and if error code reappears, replace control board (clock).
• F1-E6 - Latch Signal Mismatch Error - Disconnect power for at least 30 seconds and then reconnect. Allow at least a minute after power has been restored and if error code reappears, replace control board (clock).
• F1-E9 - Stack Overflow - Disconnect power for at least 30 seconds and then reconnect. Allow at least a minute after power has been restored and if error code reappears, replace control board (clock).
• F1-E3 - Wiring Harness Cavity Size Does Not Match Stored Value - Check the jumpers in the harness to make sure they agree with the actual oven size.
• F2-E0 - Shorted Touch Pad (Keypad) - Check the connection between the touch pad (keypad) and control board (clock) to make sure it is secure. Select the 'cancel' function and wait 60 seconds. If error code reappears then replace the touch pad, or touch pad and control board (clock) if all one assembly.
• F2-E1 - Touch Pad (Keypad) Cable Unplugged - Check the connection between the touch pad (keypad) and control board (clock) to make sure it is secure. Select the 'cancel' function and wait 60 seconds. If error code reappears then replace the touch pad, or touch pad and control board (clock) if all one assembly.
• F2-E5 - Cancel Key Line Open - Check the connection between the touch pad (keypad) and control board (clock) to make sure it is secure. Select the 'cancel' function and wait 60 seconds. If error code reappears then replace the touch pad, or touch pad and control board (clock) if all one assembly.
• F2-E6 - Cancel Key Line Open - Check the connection between the touch pad (keypad) and control board (clock) to make sure it is secure. Select the 'cancel' function and wait 60 seconds. If error code reappears then replace the touch pad, or touch pad and control board (clock) if all one assembly.
• All F3-E Codes - Oven Temperature Sensor (RTD) or Warming Drawer Defect - Replace oven temperature sensor (RTD).
• F4-E1 - Meat Probe Defect - This error indicates a problem with either the probe, receptacle, or probe circuit. Check the probe for pinched wires and make sure there is no condensation or contamination on receptacle. If ok, replace probe.
• All F5-E Codes - Door Switch Defect - This occurs when the door switches do not match. If door is latched, disconnect power from unit and check wires and connections. If damage is found, replace appropriate part. If connections are not damaged, reconnect power and hold down any key until the F5 error clears. Once the F2 code appears, select 'cancel' and observe for one minute for errors. If door is NOT latched, disconnect power from unit and check wires and connections. If damage is found, replace appropriate part. If connections are not damaged, measure door switch (door open = latch open) and latch switch (unlatch = switch open) and replace either if defective. If corrections are made during any step, power should be reconnected and the unit should be tested. Press and hold any key to clear the error code and F2 code should appear. Select 'cancel' and observe for one minute for errors. If error continues, disconnect power and replace control.
• F6-E1 - Return Line Not Connected - Replace control board (clock).
• F7-E1 - Common Switch Is Defective - This error occurs when common wire to latch switch and door switch is shorted. Check all connections at control board and at the latch switch and door switch. If connections are ok, then check individual switches as outlined for the F5 error code. Note: Double ovens will have two of each switch and one common wire.

2 Digit Failure Codes

• F0 - Control Board Failure - Replace control board (clock).
• F1 - Control Board Failure - Replace control board (clock).
• F2 - Oven Temperature Is Too High - Check for welded contacts on bake and broil relays. If present, replace control board (clock). For SELF CLEAN models, check door lock operation. Check sensor, sensor harness, and the sensor harness connection at sensor and oven control. Also check for any causes of high resistance in the oven temperature sensor circuit. Remember: The oven control board (clock) measures resistance of sensor circuit, not actual oven temperature.
• F3 - Oven Temperature Sensor (RTD) Open - Replace oven temperature sensor (RTD).
• F4 - Oven Temperature Sensor (RTD) Shorted - Replace oven temperature sensor (RTD).
• F5 - Control Board Failure - Replace control board (clock).
• F7 - Function Key Stuck On ERC - Replace control board (clock).
• F8 - Control Board Failure - Replace control board (clock).
• F9 - Oven Door Lock Failure - Check door lock switches and wiring. Make sure lock switch is not stuck.
