Samsung FX510BGS/XAA - FX710BGS/XAA

Checking Error Codes:
There are two kinds of error codes. One denotes an oven temperature sensor error and the other denotes a safety error. Possible error codes during use can be checked before service.
1. Press Clock pad to select “AM” or “PM”. Each time the pad is pressed, the display toggles to the other setting.
The default setting is “PM”
2. Press the number pads 1,2,3 and 4. Make sure the Kitchen Timer and Warming Drawer are both turned OFF.
3. Press the Start pad.
4. Press the Custom Cook and the 0 number pads at the
same time for 2 seconds. Error codes are displayed.
5. Press the 0 number pad, to display the latest 5 error codes.
If the power is interrupted and the oven turns off, the stored error codes are deleted.
6. Press the Clear/Off pad to return to normal display mode.
Natural Gas to LP Conversion :
The natural gas to LP conversion kit that is included with the range contains an orifice for the oven bake and broil burners, each of the surface burners and in the case of the FX710 that has a dual burner (right front), two orifices of different sizes. The FX510 does not have the dual burner.
All orifices must be replaced with the proper size orifice. Each is stamped with the size and is color coded. The color on the orifice corresponds with the color of the gas valve that controls the burners and the face of the orifice is stamped with the color as well.
After replacing the surface burner orifices, there are no adjustments necessary to the burners. If the burner flame is not correct, too high or too low, after verifying the correct orifice is installed the gas valve can be adjusted.
The LP conversion requires this regulator to be set for different pressures as LP gas is operated at higher pressures than natural gas.
From inside the warming / storage drawer reach in and open the red cap on the regulator. Using a 5/8” socket, open end wrench or adjustable wrench, remove the LP regulator stud and set it to the correct position.
The default position of the regulator is set for natural gas. To convert to LP remove the brass regulator using a 5/8” wrench or socket and turn it upside down.
Oven Burner Adjustment.
To adjust the shutter, loosen the locking screw and rotate the shutter towards the open or closed position as needed. If flames are lifting off the burner ports, gradually reduce the air shutter opening until the flames are stabilized. If flames are too yellow and/or too large, gradually increase the air shutter opening until the flames have approximately a 1-in blue cone. If the range is set up for natural gas, the flames should burn with no yellow tipping. If the range is set up for LP gas, small yellow tips at the end of the cones are normal. After the flames are adjusted properly, shut off the oven, retighten the locking screws, replace the oven bottom and racks.
ERROR CODES CAUSES AND SOLUTION

Troubleshooting
Warming drawer heater is not working. (FX710 Only
Measure the resistance of the warming drawer heating element.
Normal: ~24Ω
Check the warming drawer terminal on the main board and the element (T606)
Check the warming drawer relay (RY605) on the PCB.
Measure the voltage to the heating element
Normal: 120VAC
Replace the warming drawer heater Clean connections
Replace the main Board
Convection fan not working
Measure the resistance of the convection fan motor.
Normal: ~26 Ω
Measure the voltage to the fan motor
Normal: 120VAC
Check the connections to the fan motor
Check the fan relay (RY607) on the main board.
Replace the fan motor

Check the connections to the heater and the main board (T607)
Check the heater relay (RY606) on the main board.
Replace the warming drawer heater
Clean connections
Replace the main board
None of the surface burners will light
Check the gas supply to the range
Check for burner spark
Check the igniter switch connection at the spark module
Open the gas valve to the range
Check the igniter switches—Turn the gas off and disconnect the electric to the range. Turn the igniter switches one by one to the 11:00 position to simulate
“Lite” and measure the resistance of the switches at the spark module.
Normal: 0Ω (only in this position)
Check the spark module
Only one of the surface burners will not light
Because of the placement of the orifice, even though the burner cup is protected, it is possible for spillage to get into the cup and block the nozzle
Clean or replace the orifice with the correct Size.
All surface burners will light but will not stay lit
Check for crimped or restricted gas lines to the surface burner manifold
Check the main gas supply valve is turned on completely
Check the LP converter in the regulator to make sure it is in the correct position
Oven Temperature Errors 
Burner will not light Check the HSI (Igniter)
Check the wiring to the HSI
Check the connections to the safety valve
Check that the safety valve is wired correctly
Replace the Igniter
Reseat or repair the wiring
Wire the safety valve correctly
Burner will light but not stay lit
Check the connections to the safety valve
Check that the safety valve is wired correctly
Check that the burners have the correct orifice size for the gas being used
Check the air adjustments for proper flame
Check that the regulator has the correct position of the LP converter Reseat or repair the wiring
Wire the safety valve correctly Place the regulator LP converter in the correct position for the gas being used
Using the Bake or Broil function the oven does not seem to be heating correctly
(The measured temperature in the oven does not match the display)
Check the connections to the temperature sensor
Check the resistance of the temperature sensor
Check for any stored errors
Check that the burners have the correct orifice size for the gas being used
Check the air adjustments for proper flame
Check that the regulator has the correct position of the LP converter
Reseat or repair the wiring
Check that the burners have the correct size orifice for the gas being used.
Place the regulator LP converter in the correct position for the gas being used
Note: If the temperature is more that 15 degrees off from the display, it is possible that the temperature sensor has changed value. If the sensor changes value the oven display will be set to the desired temperature but the actual temperature in the oven cavity will be different. If the temperature in the oven compartment is slightly off the user has the ability to offset the temperature ±30 degrees as outlined in the owner's manual. More than that, suspect a sensor that has changed but is not bad enough to display an error.
The hot surface igniter will not come on:
Check the igniter with a meter, you should have continuity through the HSI. If open replace the HSI. HSI’s do weaken and will eventually generate less heat than they normally could. When this happens they can still allow marginally correct current to flow to the oven gas valve for it to open but not get quite hot enough to ignite the gas burner immediately. When this happens, gas released into the oven can sometimes build up to the point where when finally ignited, the amount of gas lit can cause a small explosion inside the oven or cause an odor of gas without the oven working
