I have been told I have a bad digital panel on my Hayward H250 pool heater with electronic ignition, which is 9 years old. Can I by pass or jump the digital board in the control panel. The heater starts but does not light the burners. I have been told the problem is in the digital board, which is very expensive to replace. To be sure its the digital board I need to be able to by pass the board and start the heater.
