I have a Laars LX/LT, LX400L heater. It has been working good lately. The other day I tried to to the heat the pool a little. The console said that my water temp. was over 100 degrees (F). The water only felt like it was low 80's. When I turned on the heater it wouldn't fire up cause it thinks the water is way above the temp I want. Is there anyway to adjust the temperature of the water on the heater? Is something broken that I need to replace. I'm not to bad at trouble shooting, but I'm at a stand still. Anyone have any ideas. Thank you.
