Henny Penny Electric Fryer Error Code E-5: Fryer Too Hot
E-5 / FRYER TOO HOT means the controls sense 405 F or higher. Turn the fryer off and let it cool. A technician should check the heat parts and the temperature probe.
High: oil at this temperature is a burn and fire concern, so the fryer must not be used until checked.

What does Henny Penny E-5 FRYER TOO HOT mean?
The Computron 1000 control watches the oil temperature all the time. If the reading reaches 405 F or higher, the control shows E-5 / FRYER TOO HOT. That is well above normal frying temperatures, so it either means the oil really got that hot or the control is misreading it. The manual's action is to have the heat parts and the temperature probe checked. Those two checks cover both possibilities: a heat circuit that stays on when it should switch off, and a probe that reads too high. The high limit is a separate safety, shown as E-10. E-5 is the earlier warning from the control itself. Cooks see the heating stop and the display flash the message. Because hot oil is a burn and fire concern, the fryer should be left alone while the oil cools. The manual gives no operator reset steps.
