Question about Jandy Laars Lt 400,000 Btu Heater
Burner continues to operate when pump switched off. low pressure sw operates correctly, and 24v present at both white leads to gui. normally when pump switched off,heating ceases, and "low pressure" comes up on gui display. this no longer happens. heating works normally only when pool/spa/off is made to "off" after pool temp is brought up to required temp, then made to "pool" when heating required again.at no time does the "low pressure" warning come up.
Replace or adjust pressure switch to have heater go off when pump is off

You must turn on the pump and let water circulate through the pool and the heater before you turn on the heater otherwise you will ruin the heater

If the unit is lighting then shutting off then repeating it isn't rectifying, means not sensing the flame. May have a bad flame sensor or ignition control. I'm guessing your AGS is indicated on the GUI also.

You have a serious issue call a qualified heating or mechanical contractor sounds like a lock out or solenoid which is designed to shut off gas/flame for things like not blowing your backyard up is doing it's job. Or take the advice of a faceless stranger and hope you get it right 400,000 btu is about 7 x's the average home furnace so should be quite a boom
