The booster heat control circuit is controlled by the relay board. Visually check for loose or burnt relay contacts...
You will see the booster LED light when it calls for heat. Some newer machines have a second high limit on the right hand side of the booster tank.
It may be your control board is configured for low temp with no booster. When you power up, the display should say LX30H. If not
Pull open the upper drawer, place a magnet over the door interlock switch.
CAUTION, 220 volt power is present. be carefull what you touch.
on control board, short J5-1 and J5-2, then power up. You are in factory setup. press select on the control board to see each option on the front panel., press up arrow on control board to step up through options for each step. when done, press the off button on front panel. remove short and start up normally. With the magnet in place, AND THE DOOR CLOSED, run the machine and observe the relay board status lights.
If you want to adjust the temp set points, with the machine off, press and hold the hidden key behind the front panel logo, and press select on the control board.. Or on power up, hold the wask key..Same to adjust options as above. Press off to exit.

on the gas valve there is an adj. for the pilot size, maybe too small , would try increasing the pilot and see what happens.also the thermocouple might be on the way out ,you might want to replace that and try oper. go with thermocouple first, then try pilot size dont forget to vote tks. monomoy

Have you tried shutting down all power to your oven at the electrical panel, waiting 10 minutes and then returning power to the unit? Procedure could reset the defaults. Best of luck.
