    Hayword h250 natural gas heater

    Ok , I need some help., my heater is 4 years old, this year, it attempts to fire but wont stay running, then gives the "IF" lights on display, I have checked flow, cleaned filters again, still nothing, I had a buddy come over and he jumped the flow sensor still nothing, someone give me a hint before I have to spend big bucks having a technician come over n look at it.

    Welcome to TFP!

    First make sure the gas is turned on. Second, try blowing or vacuuming up any debris that might have accumulated in the air intake or around the burner.
