Henny Penny Pressure Fryer Error Code E-10: High Limit Tripped
E-10 on a Henny Penny pressure fryer means the high limit has tripped, cutting the heat because the oil passed a safe temperature. Turn the fryer off and let the oil cool completely. Once cool, press and hold the red rocker reset switch for 5 seconds; if E-10 returns, stop cooking and call us.
High: a safety switch has cut the heat because the oil was too hot, and the fryer will not run until it is reset.

What does Henny Penny error code E-10 mean?
Henny Penny fryers carry a high-limit switch that is separate from the normal temperature control. If the oil climbs beyond a safe temperature, the switch opens and removes heat from the vat no matter what the cooking control is asking for. The control then shows E-10 and holds it until the switch is reset. This is a protection, so the fryer stays down until the oil is cool and the switch has been reset by the step the maker gives owners. A reset only tells the fryer it may heat again; it does not explain why the oil got that hot. The usual questions are whether the temperature probe and heat control were reading true, whether the high-limit switch itself is sound, and whether the drain was opened while the fryer was heating. Because hot oil is involved, the first rule is to leave the fryer alone until the oil has cooled. The display text is E-10.
Affected models and control systems
Henny Penny pressure fryers from the PFE 500, PFE 561 and PFG 600 onward, as described in the iControl-era online help.

What you may notice
- E-10 on the display
- Fryer not heating
- Oil well above normal temperature before shutdown
Possible causes
Listed in Henny Penny's documentation
- Reason the oil got above a safe temperature
- High-limit switch tripped and needing reset
- Temperature probe and heat control
- Drain opened while the fryer was heating
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.
- A temperature probe reading low so the heat stayed on too long
- A heat control that does not cut off after reaching setpoint
Safe checks before calling for service
- Turn the fryer off and give the oil time to cool.
- Once cool, press and hold the red rocker reset switch for 5 seconds, as the owner's manual lists.
- If it will not reset, the high limit has to be replaced, so call us.
- Never drain hot oil to speed cooling.
- If E-10 returns after a reset, stop cooking and call us, and tell us what the oil temperature reading showed beforehand.
How a technician diagnoses error code E-10
- Confirm E-10 and let the oil cool before any inspection.
- Reset the limit as the maker directs and watch whether it holds.
- Check the temperature probe reading against a known thermometer.
- Test the heat control and its contactor with a meter.
- Test the high-limit switch for continuity when cool.
- Replace the limit only if it will not reset, and fix the control problem behind it.
- Hot oil can seriously burn, so the vat and its probe are handled only when cool and with the right gear.
- The heat circuit runs on high-amperage line voltage, so meter tests are for a trained technician.
- A limit that resets does not tell us why it tripped, and a repeat trip means the probe or control needs replacing.

Can I reset it right away?
No. Let the oil cool completely first, then use the reset as the manual describes.
What if it will not reset?
The manual says the high limit has to be replaced. That is a service call.
Will E-10 come back?
It can if the probe or heat control caused the overheat, so repeats need testing.
