I have a Teledyne LAARS Lite 2 pool heater that was installed in 2002. The igniter was working but the heater was shutting off before it reached the targeted temperature. I cleaned the main filter assuming the pressure may have been shutting off the heater. This was resolved but now the igniter is not working and I noticed the pressure switch has a small leak. I'm hoping someone can give me some guidance on trouble shooting the problem(s).
