Hi, My name is Anthony and I desperately need some help, as I am pulling out what's left of my hair.
I have a Hayward H350FDN Pool heater that lights only when it feels like it. I will provide every detail I have including what has already been tried, in order to help you, hopefully, help me.
I have spent the last 4 hours reading through everything written on here that is even remotely related to my problem and can't find a solution that I have not already tried (it's possible I missed it as my vision is starting to blur).
Here is the situation:
Situational observations: (may or may not be relevant)
What has been done to try to fix it: (by professional pool guy (at great expense))
Final thoughts:
I considered my problem could still be a spider web, as it worked for 36 hours after my pool guy cleaned it.Then the problem started again. It's possible that he cleared the web, but not the spider, who promptly got to work on a new web. If that is the case, why does is still work every morning?
Thank you in advance for any and all suggestions you might have. My pool guy said he doesn't know what else to do and is considering calling an industrial boiler expert $$$$ Im terrified at what that might cost!
If you need any additional information to help address my issue please let me know and I will provide what I know.
Thank you

Here is the situation:
- Heater will come on, pre-ignition fan will start, and I will hear the whoosh of ignition and feel heat out of the top vents. That will last between 2 and 5 seconds then goes off. As designed, it will try again in about 30 seconds until it has gone through 3 cycles, then the dreaded IF code is displayed.
Situational observations: (may or may not be relevant)
- For some reason the problem is intermittent and seems to have a lot to do with either outside temperature or time of day. It will fire and stay lit almost without fail first thing in the morning. Almost never during the heat of the day, and when it is in the mood in the evenings.
- Heater seems to be slightly more reliable when the weather is cooler.
- It is most likely to work when I first turn the pump on and almost NEVER when the pump has been running a few hours.
- Sometimes being stubborn helps, if I try 4 or 5 cycles of 3 (that's 15 start attempts) sometimes it will light and stay lit.
What has been done to try to fix it: (by professional pool guy (at great expense))
- Confirmed gas is on and the gas line is clear with sufficient pressure
- New Igniter
- New flame sensor
- shop vacuumed out the entire unit
- Taken off the burner nozzle and cleaned out each orifice (the spider web fix).
- Both new and cleaned filters have been used
- sufficient water flow confirmed
