Henny Penny Electric Fryer Error Code E-6: Temp Sensor Failed
E-6 (A or B) / FRYER TEMP SENSOR FAILED means a failed temperature probe or a bad connection. Have the temperature probe and its connection checked.
High: the control cannot read the oil temperature, so the fryer stops heating.

What does Henny Penny E-6 FRYER TEMP SENSOR FAILED mean?
The Computron 1000 control needs the oil temperature probe to know when to heat and when to stop. When the probe or its connection fails, the control shows E-6 / FRYER TEMP SENSOR FAILED, with an A or B after the number. The manual treats the A and B forms together on this control, with a single meaning: a bad probe or a bad connection. It lists one action, have the probe and its connection checked. The older technical manual for the same fryer family shows E-6A and E-6B instead, and the Computron 1000 table combines them. A probe fails when its wire breaks, when its connector corrodes or loosens, or when the sensor itself drifts out of range. The control cannot heat safely without the reading, so frying stops. The cause is usually simple to find with a meter, but the fryer must be cool and isolated first.
Affected models and control systems
Henny Penny OFE-321 and OFE-322 electric open fryers with the Computron 1000 control. The manual we used is a text viewer copy. The display shows E-6 with an A or B, and the manual treats both as the same failure.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
