Henny Penny OFG-391 Fryer Error Code E-5: Shortening Overheating
E-5 means the shortening is overheating. Turn the fryer off, then on, and if it still shows, check the heating circuits and the temperature probe; after cooling, if it persists, the control is replaced.
High: overheated shortening is a burn and fire concern, so the fryer must be checked.

What does Henny Penny error code E-5 mean?
The controller watches the shortening temperature through the probe and shows E-5 when the reading is above what it will allow. This is a different alarm from the high limit, which is a separate safety device. The manual's action is in three steps. Turn the fryer off, then on. If E-5 still shows, check the heating circuits and the temperature probe, because the shortening may really be overheating or the probe may be reading wrongly. After the fryer has cooled, if the message persists, replace the control. Hot shortening is a burn and fire concern, so cooks should not move or filter oil while E-5 is active. The first reset is for a brief upset only. A real overheating means the gas burner is not shutting off when it should, and that is not an operator repair. A technician will usually compare the probe against a reference thermometer in the oil first, because that single test shows at once whether the oil is really hot or the control is being misled by a bad reading.
