Hi everyone,
I've had my Jandy LX400 heater for almost 10 years now, and I ran into an issue the other night when attempting to use the spa. The GUI panel indicates that I have an air flow sw issue and the heater will not stay on. The exhaust area is clear for exhaust air flow, and the blower definitely does come on. The heat kicks in too. But once it's lit and I can feel the hot air blowing out of the exhaust area for a while, it shuts down and the error message appears on the screen.
Reading the inside of the heater panel that I removed, it says that this error indicates that there is an open between the terminals of the blower pressure switch. But I don't know what's causing the open in the first place. I suppose the switch itself could be bad, or there is a blockage in the small rubber tube that's connected to the top of the switch. I'm just wondering how I can determine whether or not I need to replace the blower pressure switch.
I've read that there is a reset switch inside the unit near where the water connections are. I have located where this would be, but I can't press the switch at all to attempt a reset (if in fact what I found is actually a switch).
Where's the best place to start?
Thank you!
Greg
