Henny Penny Pressure Fryer Error Code E-46: Control Memory Failure
E-46 on a Henny Penny Velocity pressure fryer reports a failure in the control's memory, so it cannot store or recall its program reliably. Switch the fryer off and back on, and note your usual cook settings on paper. If E-46 returns, stop using the fryer and call us.
Medium: the fryer may not cook reliably, and the cause is a control memory problem rather than an overheating condition.

What does Henny Penny error code E-46 mean?
The control depends on memory to hold its program between cooks and across power-down. E-46 is shown when that memory cannot store or recall the program reliably. The control may then stop cooking or behave oddly, because it cannot be sure which settings it is working with. The maker's help page gives the same first steps as for lost settings: switch off and on, then set the control up again, and replace the board if the setup does not hold. The difference from E-41 is in what is being reported: E-41 says the settings are gone, which can follow a power event, while E-46 says the memory itself failed. A setup that does not hold means the board is likely at its end, but unstable power can also cause memory trouble, so both are checked before a new board is recommended. Grease on the control face is worth wiping away. The display text is E-46, and it applies to the PFE 561 and PFG 600.

Safe checks before calling for service
- Switch the fryer off and back on, as the owner's manual lists.
- Note your usual cook settings on paper.
- If E-46 returns, stop using the fryer and call us.
- Keep grease away from the control face.
- Tell us how many times it appeared and whether the settings held between visits.
How a technician diagnoses error code E-46
- Confirm E-46 and check the supply voltage at the fryer.
- Power cycle and attempt a fresh setup, watching for acceptance.
- Check whether the setup holds after several power-downs.
- Inspect the control connectors for corrosion or grease.
- If the setup will not hold, replace the control board.
- Re-enter settings and verify temperature and timing against a thermometer.
- The control board lives in the cabinet beside the vat and shares space with line-voltage wiring.
- Power quality can also cause memory trouble, so we test the supply before recommending a new board.
- Reprogramming a fryer control with the kitchen's own cook settings needs the service procedure for the model.
