Error Codes

DISPLAY	CAUSE	PANEL BOARD CORRECTION
“E-4”	Control board overheating	Turn switch to OFF position, then turn switch back to ON; if “E-4” continues, the board is getting too hot; check for signs of overheating behind the control panel; once panel cools down the controls should return to normal; if “E-4” persists, have control panel replaced
“E-5”	Oil overheating	Turn switch to OFF position, then back to ON; if “E-5” continues, the heating circuits and temperature probe should be checked; once the unit cools down, the controls should return to normal; if “E-5” persists, have control panel replaced
“E-6”	Temperature probe failure	Turn switch to OFF position, then back to ON; if the “E-6” continues, the temperature probe should be checked; once the probe is repaired, or replaced, the controls should return to normal; if “E-6” persists, have control panel replaced
“E-41”	Programming failure	Turn switch to OFF position, then back to ON; if display shows “E-41”, the control should be re- initialized (See Programming Section) if the error code persists, have control panel replaced
“E-71”	Pump motor relay failure or wiring problem	Replace relay if contacts are stuck closed; check wiring on POWER/PUMP switch, or at wall receptacle; L1 and N may be reversed
“E-32, FAN FAIL ERROR, CHECK BLOWER, CLEAN DILUTIONBOX, CALL HENNY PENNY SERVICE”	Air pressure switch open; clogged dilution box or faulty blower; open drain switch; open high limit	Clean dilution box or replace blower if necessary; have drain switch checked; reset high limit or have high limit checked

CE Only - Along with the previous error codes, CE units have the following self-diagnostic error codes:

DISPLAY	CAUSE	PANEL BOARD CORRECTION
“E-10”	High limit	Allow oil to cool, and then reset the high limit by manually pushing and holding the reset (red rocker) switch for 5 seconds. If the high limit does not reset, the high limit must be replaced.
“E-15”	Drain switch	Close the drain, using the drain valve handle; if display still shows “E-15”, have the drain microswitch checked
“E-20A”	Air pressure switch failure	Press the timer button to try the ignition process again, and if “E-20A” persists, call Henny Penny’s Service (stuck closed) Department
“E-20B”	Draft fan or air pressure switch failure (stuck open)	Press the timer button to try the ignition process again, and if “E-20B” persists, call Henny Penny’s Service Department
“E-20C”	Left gas module failure	Press the timer button to try the ignition process again, and if “E-20C” persists, call Henny Penny’s Service Department
“E-20D”	Right module failure	Press the timer button to try the ignition process again, and if “E-20D” persists, call Henny Penny’s Service Department
“E-20E”	Both modules failure	Press the timer button to try the ignition process again, and if “E-20E” persists, call Henny Penny’s Service Department
“E-20F”	Left module no flame sense	Press the timer button to try the ignition process again, and if “E-20F” persists, call Henny Penny’s Service Department
“E-20G”	Right module no flame sense	Press the timer button to try the ignition process again, and if “E-20G” persists, call Henny Penny’s Service Department
“E-20H”	Both modules no flame sense	Press the timer button to try the ignition process again, and if “E-20H” persists, call Henny Penny’s Service Department

E-20 without a Letter

Cause

Are you getting an E-20 error with no letter after the error, a strong pilot, and good flame rectification?

Solution

Check the solenoid valve for a short. A short in the solenoid valve can cause most of the 24 V system to disconnect.

Try disconnecting pressure solenoid valve or turning pressure off in cooking program to see if ignition problem goes away. If it does, the short in the pressure solenoid was the root cause.

Ensure the flame sensor wires are going to the correct ignition module.
