Hello all, looking for some help. I have a hayward h350 IDL2 gas heater. It is wired direct to fuse panel, no timer in between. Keeps blowing F2 fuse when i turn it on. Replaced fuse still blows. Replaced transformer still blows. Talked to hayward tech on phone,went through some tests with him and he said was transformer, bought new transformer installed and still blew same fuse. Im at wits end with this thing. Please help.
