Jandy LX400P-L Heater

My propane heater burns for about 10 seconds then quits. It starts backup burns for another 10 seconds then quits. It cycles like this for about 10 minutes then gives an air pressure switch error code. I've installed a new air pressure switch, a new low pressure Propane gas regulator, and removed and cleaned the flame sensor. But so far none of that has worked. Any other suggestions?

This is probally your ignition wire is bad and not reading flame at the pilot or your pilot is bent or something so that when the pilot lights the flame isn't hitting the sensor probe at the pilot. When looking under the heater use a mirror so if you get roll out of the flame you don't get burned. Good luck and be careful.

This indicator normally means that your water temperature in the pool heater exceeds the internal limit. The corrosion should not be causing this problem. Since the high temperatures can be dangerous, you will probably have to contact a pool professional to service the machine.

Teledyne Pool Heater


I am having the same issue. The heater will go through a cycle of where first a blower starts, then the heater ignites, runs for about 10 seconds, and then stops. Then it does the whole cycle again. It will do this over and over.

I have read the problem is that the ignition detection switch may not be working. they suggested using some emory paper to clean it off, and then try again.
