Hi there!
I have a Haywood natural gas pool heater, H250FDN. I've being trying to diagnose a problem with the display as it is blank. The heater itself is functional and running but I would like to see what is actually going on!
So far, I have checked the four fuses on the fuse board and all are good. I also checked the spade fuse on the main board; it is good too. Any suggestions as to what else to check? Any ideas as to what may be wrong?
Thanks,
P.S. I did a bit for searching before posting this. Seems most people got an error code. I have not seen one yet.
