Henny Penny OFG-391 Fryer Error Code E-10: High Limit Tripped
E-10 means the high limit has tripped. Manually push up on the red reset button. If it will not reset, the high limit must be replaced, so call the Service Department.
High: the oil exceeded a safety limit, so the fryer must not be used until the cause is found.

What does Henny Penny error code E-10 mean?
A high limit is a safety thermostat that cuts the heat if the oil goes above a safe temperature. On the Henny Penny OFG-391 open gas fryer it is a separate device from the probe that controls normal frying. If the oil gets too hot, the high limit opens and the controller shows E-10. The manual's action is to manually push up on the red reset button, and if the limit will not reset, it must be replaced, so call the Service Department. A tripped limit means oil temperature went beyond what the normal control allows, or the limit has weakened with age. Resetting restores the heat but not the cause. If E-10 comes back soon after a reset, the temperature control or the limit itself needs attention. Always let the oil cool before touching the red button.

Possible causes
Listed in Henny Penny's documentation
- High limit tripped
Other likely causes — what usually sits behind error code E-10 on this control. A technician confirms which one it is before any part is replaced.
- Temperature probe or control reading low so oil overheated
- Vat refilled too little after filtering so the oil sits below the high limit sensing point
- High limit weakened and tripping early
Safe checks before calling for service
- Turn the fryer off and let the oil cool completely.
- Push up on the red reset button as the manual says.
- Restart and watch the oil temperature.
- If it trips again or will not reset, stop and call us.
How a technician diagnoses error code E-10
- Read the code and confirm E-10.
- Let the oil cool and reset the high limit.
- Compare the temperature probe reading with a thermometer.
- Check the oil level and the heating control.
- Replace the high limit if it will not reset.
- Hot oil is a burn and fire hazard, so repeat overheating needs a proper diagnosis.
- The limit and control circuit carry gas-fryer controls and line voltage.
- A limit that will not reset must be replaced, not bypassed.
