    hayward heater help, please

    i got a hayward 100k above grd pool heater which will not work. induced draft fan won't spin, nothing. however if i jumper the 2 wires across the water pressure switch it will run fine. thought i had a bad water pressure switch, got a new one, still the same thing. my filter is running fine on high and low speed. took the pressure switch out and the high limit switch's then removed plug and got lots of water shooting up like geysers from the manifold with filter off. i thought maybe something was blocked. but wasn't. any help would be appreciated. thank you in advance for any info for me to try.

    You're saying that even now if you jumper the pressure switch the unit runs? If so it sounds like you got a bad pressure switch or maybe the wrong one.
