ERROR 
CODE 
(SYMPTOM) 
 

 
F01 + beep 

 
Temperature in the exhaust duct raised above 260 F due to  

a)  Fire in the cavity 
b)  Clogged air filter (not applicable to OCS models) 
c)  Obstruction of the exhaust duct 
d)  Shorted temperature sensor

F03 or F04  

 
Mismatch between the incoming line voltage and the voltage setting of the oven. 

a)  Make sure the line voltage corresponds with the setting of the oven. The 

voltage selector is located at the back and consists of two plugs. The white 
plug sets the oven for 208 V and black plug (or white plug with a black dot) 
sets the oven for 230 V. 

b)  Make sure the line voltage is within +/- 10% tolerance. This is especially 

important during summer months, where line voltage has tendency to drop. 

c)  If both steps above check OK, the error(s) may be caused by defective 

controller (DPU) board

F05  
 

 
Internal memory failure has occurred. Replace the controller (DPU) board 

 
PRO-1 

 
F09  
 

 
Oven that was designed for 50Hz electricity is attempted to operate in the 60Hz 
environment. If the model number of the oven in question is listed above, most likely 
the controller (DPU) board has failed. 
 

 
PRO-1 

 
F33 or F34  

 
These codes may be triggered by either excessive heat within the oven or poor 
grounding of either the temp sensor or the controller (DPU) board.  Check the 
following: 

a)  Clogged air filter (not applicable to OCS models) 
b)  Obstruction of the exhaust duct or insufficient ventilation 
c)  Defective thermal sensor (should read 30 – 70 kohm in room temperature) 
d)  Grounding of the thermal sensor (possible oxidation) 
e)  Poor connection (oxidation) at CN4 connector (PRO-1 models only) 
f)  Poor or no ground at the controller (DPU) board – ensure that all screws 

securing the board are in place 

g)  Missing screw(s) that secure the escutcheon to the frame (OCS models 

only) 

h)  If all steps above check OK, the error(s) may be caused by defective 

controller (DPU) board

This code will appear if there is malfunction of the keypad. Check: 

a)  Ribbon connector of the keypad for conductive residue or oxidation 
b)  Perform continuity test of the keypad (use matrix shown in the service 

manual - DPU circuit diagram) 

c)  Replace the keypad, if both steps prove to be inconclusive
