Hayward H250 Pool Heater

[rotorsailor]

I have a fuse kit, but can't find the automotive type fuse on the panel. Where do I look?

It should be on the Integrated Control Board (ICB).

I can see the three slow blow fuses, but not the other one. Is it somewhere on the iCB enclosed?

 

[JamesW]

There is a fuse board and a separate control board. There is a purple 3 amp fuse on the control board. Upper right corner. Control board is above the fuse board.

After looking at an enlargement of the ICB, there it was in the upper corner. Pulled it out, and it is blown. So I will be down to the pool supply tomorrow for another one (and a spare!). One thing I wasn't told when the unit was installed 5 years ago, was there was a packet inside with the 3 slow-blow fuses and the other one! It had moisture inside, so none of these now work, and I will make my own spare package that is kept in the main Hayward supply cabinet, which is water-tight. Maybe this is useful for anyone else that has had a pool heater installed. Thank you James W. for your help.

You might be able to find the fuses at a hardware store or automotive store.

The pool place might have them but probably not. Even if they have them, they will probably be more expensive.

A blown F1 fuse might be bad wiring, a bad gas valve or a bad ICB.

Purple 3 am fuse was bad. Replaced it, and the other 3 fuses are all good. Guess water must have got on the ICB. Is this difficult to replace?

 

[JamesW]

The ICB isn't too hard to replace if you think that that's what's wrong.

Did the heater work after replacing the fuse?
