Southbend EZ Com Oven Error Code Err FA:n: Limit Switch Tripped
Err with FA:n on a Southbend EZ Com combination oven means the cavity temperature limit switch or the motor's centrifugal switch has tripped, which may indicate a blower motor failure. Turn the oven off and let it cool. A technician should check both switches and the blower motor.
High: a tripped limit or centrifugal switch means the oven is protecting itself from overheating or a motor problem.

What does Southbend error code Err + FA:n mean?
The oven has two protective switches that this code covers. The cavity temperature limit switch opens when the oven interior gets too hot. The centrifugal switch is part of the blower motor and opens if the motor does not reach or hold its running speed. When either trips, the controller shows Err in the TEMPERATURE display and FA:n in the TIME display. The manual says the tripped centrifugal switch may point to a blower motor failure, and it gives no further steps beyond fixing the cause and turning the unit off and on. Because two quite different problems share the code, the first job is to find which switch opened. A hot oven with a healthy motor points to the limit switch, and a motor that is slow, noisy or silent points to the centrifugal switch.
Affected models and control systems
Southbend EZ Com combination ovens CG/12SC and CG/22SC.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
What you may notice
- Err shows in the TEMPERATURE display and FA:n in the TIME display
- The oven stops heating
- The blower sounds different or does not run
- The cavity was very hot before the code
Possible causes
Listed in Southbend's documentation
- Tripped cavity temperature limit switch
- Tripped centrifugal switch (possible blower motor failure)
Other likely causes — what usually sits behind error code Err + FA:n on this control. A technician confirms which one it is before any part is replaced.
- Grease or debris around the blower that slows the motor
- A limit switch that opened after an earlier overheating event
Safe checks before calling for service
- Turn the oven off and let it cool completely.
- Listen when you turn it on again for the blower to start and run smoothly.
- Do not run the oven if the blower is silent or noisy.
- Write down whether the oven was hot or the blower sounded wrong, and call us.
How a technician diagnoses error code Err + FA:n
- Read the code and confirm Err and FA:n.
- Check which switch opened, the limit switch or the centrifugal switch.
- Test the blower motor for free rotation and normal current.
- Check the limit switch after cooling.
- Inspect the cavity for the reason for any overheating.
- Replace the motor or switch after the test.
- The blower motor and switches are behind panels with mains voltage and moving parts.
- Telling an overheating event from a motor problem needs a meter and observation of the blower.
- A tripped limit switch means the cause of the overheating has to be found.
How error code Err + FA:n differs from similar codes
FA:n covers the limit switch and the centrifugal switch, while GA:S is the gas error and Pr:0b is the probe error.

Is FA:n a gas code?
No. It relates to the limit switch and the blower motor's centrifugal switch.
Could the blower motor be failing?
The manual says the centrifugal switch may indicate a blower motor failure.
Can I restart it?
After cooling, but if the code returns, stop and call us.
