Question about Jandy LAARS LX250 - PROPANE, DIGITAL READ-OUT, LOW NOX
My Air Flo SW is on. I have vacuumed and cleaned the top under the plastic vent and inside the unit. The heater comes on perfectly and heat is coming out, but when the blower kicks on full, it shuts down

Mine does the same. Sounds like you checked the air pressure switch, but the high temp switch and bad airflow can also cause this problem. Check the two white wires that lead to the heat sensor vent drain tube exits. Make sure the spade connectors aren't shorted. Try testing the temp sensor like you did the pressure switch to make sure the circuit is properly closing when in use (or use a temporary jumper to bypass as a test.) Check the bottom of the pan for any dust or crud that could block the airflow below or around the burners and last of my options- increase clearance around the unit to aid air flow.
