Hello, I have a H150FDN pool heater. It's worked all summer so far, but last week I noticed that it would turn on for a few minutes then turn off and show Lo. The filter is clean and the output is strong. I ordered a new pressure switch, but in the meantime I took the two wires that connect to the switch and made a jumper and connected it thinking that it would keep the heater on all the time until the new switch came, but it didn't - it turned on and off. Is it possible the new switch will help or could there be another issue? Thanks!
