Henny Penny Pressure Fryer Error Code E-41: Program Settings Lost
E-41 on a Henny Penny Velocity pressure fryer means the control has lost its program settings, so cook times and temperatures may be gone or wrong. Switch the fryer off, wait, and switch it on again. Write down the cook times your kitchen uses and call us to set the control up again.
Medium: the fryer may not cook until its settings are restored, but heating safety is not directly involved.

What does Henny Penny error code E-41 mean?
The control keeps the cook times, temperatures and setup that staff rely on in memory. At power-up it checks that this stored program is complete. If the data is missing or does not pass the check, the control shows E-41 and the fryer may stop cooking until it is set up again. An odd power event, such as a surge or a brief outage while the control was saving, can wipe the program. A worn control board can lose it as well, and then the loss repeats. A one-time loss after a power event is different from a failing board, so the history matters: if the settings vanish again soon after being re-entered, the control itself is the cause, while a single loss followed by stable operation points to the power event. The maker's first steps are to switch the fryer off and on and then set the control up again. The display text is E-41, and it applies to the PFE 500 and PFE 561.

Safe checks before calling for service
- Switch the fryer off, wait, then on again, as the owner's manual lists.
- Write down the cook times your kitchen uses so they can be entered again.
- If E-41 stays, the control needs to be set up again, which we do with your settings in hand.
- Call us if it keeps coming back.
- Tell us whether there was a power outage or breaker trip before it appeared.
How a technician diagnoses error code E-41
- Confirm E-41 and ask about recent outages or breaker trips.
- Check supply voltage stability at the fryer.
- Reload the setup with the kitchen's cook times in hand.
- Power cycle several times and watch whether the settings hold.
- If the program is lost again, replace the control board.
- Verify temperatures and timers against a thermometer after reloading.
- Reloading a control means entering setup parameters that change how the fryer cooks and protects itself.
- A recurring loss points to the control board, which sits near line-voltage wiring and the vat.
- We write down your settings before touching anything, so your menu times return exactly as they were.
