So. After weeks of troubleshooting I manged to get a new board to work. Not sure what I did that actually fixed it. Basically I replaced the incoming electrical (220 into the transformer) from the timer to the heater. Removed and cleaned transformer and wires, including sanding the ground...

Checked the fuse all is good. Only thing I can imagine is wrong is the transformer. So inwill replace it. Thx.

Thanks for the reply @swamprat69 The new control panel came as one piece and included a new lcd screen. I am measuring the 28 VAC at the transformer load side and also at the wire harness pin connector female side using the 24 and ground connectors. I did not check for continuity across...

So I'm still stumped. I received a brand new board from the pool store and still nothing. Retested the wiring harness and I have 28 volts. Can anyone confirm if bench testing the board by providing 24v to the necessary pins will make the board light up? I see nothing in the schematic that...

Thx @swamprat69 looks like the lcd display is soldered on this board and not replaceable. Pool store ordered me another control panel. Assuming it must be defective since nothing else could be the problem. I'll update you once it arrives and is installed.

Thanks for your input. The model is a Hayward H250-ED2C. I am probably have the 6V incorrectly since I was just reading this off the control board. I am including pics of the heater with the cover off, the serial/model plate and control board for reference. I concluded that the board should...

I've searched through the forum without success. I have a 9 year old Hayward 250hed natural gas pool heater who's control board recently went blank after trying to adjust the temperature. I tested for voltage at the line side and have 28v on the load side of the transformer. I took the board...
