Picture - Henny Penny Fryer Codes and What They Mean

Many deep fryers from Henny Penny use a digital readout system called Computron 1000 or 8000. These display error codes and messages if there is something ailing the machine. But what exactly do those mean? Below is a cheat sheet with common Henny Penny error codes so you can diagnose the problem quickly.

Henny Penny Error Codes

It's important to note that if there are multiple errors, only the highest priority error will be reported. This list is in numerical order, not order of priority. Some of these errors may have a simpler fix than others (i.e. closing the drain switch). However, many errors will require more work or problem solving. Please contact an authorized technician to check electrical components inside the fryer and make any necessary repairs. 


Error Code


Issue


Resolution


E-4


The control board is overheating


Ensure the fryer has proper clearance and check for an obstruction on the side louvers of the fryer.


E-5


The oil or shortening is overheating


Check that a contactor or burner isn’t locked on. Turn unit off and on again. If fryer continues to show E-5, have an authorized technician check the heating circuit and temperature probe.


E-6


Error with the temperature probe


Temperature may be faulty, damaged or disconnected. Have these checked and repaired by an authorized technician.


E-10


The high limit has tripped; the oil is too hot, oil level too low or the unit is dry-fired


Check to ensure the contactor or burner isn’t locked on. Let the unit cool down for 15 to 20 minutes, and push the reset button. If the high limit does not reset, it must be replaced by an authorized technician.


E-15


The drain handle is open while the fryer is on


Check that the drain switch is closed.


E-20A


The fan vacuum sensor is stuck closed even when the fan is off


Check to ensure the fan isn’t running after the sensor is an open circuit. If you press the timer button, the unit will attempt to ignite again.


E-20B


The fan vacuum sensor failed to close when the fan turned on


The fan or vacuum sensor may have failed or there is a broken or disconnected wire. If the fan is actually running, the vacuum sensor or vacuum hose is defective or the wiring connections to the vacuum sensor are faulty. All these will need to be checked and repaired by an authorized technician.


E-20C


The ignition module is not responding


The ignition module is either disconnected or faulty. If this error occurs and the unit isn’t even trying to spark, there’s likely a problem with the wiring, the module itself, or the relay on the I/O board. An authorized technician will need to check and repair both issues.


E-20D


The unit is failing to ignite or sense the flame


Turn power off and on again. If the problem persists, check the gas line connections including the gas shut-off valve. If resetting does not work, have the fryer checked by an authorized technician.


E-41


Programming settings have been lost


Turn power off and on again. If this does not fix the issue, contact an authorized technician to replace the CPU board.


E-46


Faulty EEPROM write error


This only occurs if the EEPROM chip has failed or if the CPU board has a fault. The CPU will need to be replaced by an authorized technician.


E-47


The analog converter chip has experienced an Analog-to-Digital (A-to-D) failure


Check the A-to-D chip for moisture damage. Test to see if the speaker works normally by pressing a key on the control panel. If it doesn’t function, or is giving very faint sounds, then the electrical supply, I/O board and/or chip will need to be replaced by an authorized service technician.


E-48


There has been an Input System Error


This means the CPU can’t read buttons or digital inputs. This will need to be repaired or replaced by an authorized technician.
