    Puzzled with blank display

    My six year old pool is equipped with a Smart Control system and a Hayward H400 heater. I have been attempting to get my heater to work by replacing both ignition control board and the display board. I couldn't get the heater to ignite and kept getting an IF error code. Eventually, the code changed to LO without me doing anything. I decided to change out the flame sensor and while I did this, I also cleaned out the filters very good. Now, the heater display board is blank and when I attempt to turn the pump on using the Smart System, I'll hear a click and nothing. I'm thinking the pump not turning on has something to do with the heater. Any suggestions? Thank you!!!
