Question about Jandy Laars LX Pool Heater / 400,000 BTU / Natural Gas
Service-air flo, is telling us that the combustion fan is either not able to blow enough air either due to a blockage, or a fan failure, OR the air switch that detects this feature has failed, OR the rubber tubing used to connect the air-switch to the blower assembley is burned, or cracked.
Follow the tubing from the blower to the air switch to find it, then check the condition of the tubing. Replace if broken, burned , or cracked. If this is not the problem , it gets much more involved after this, and you must be familiar with a multimeter and know the internal electrical operations of the heater to troubleshoot it.
Id check the tubing, and call a certified Jandy tech if the problem persists.
