Hi,
I have a Teledyne Laars LLD heater running on natural gas.
It would not fire up when I opened the pool for the season.
It last ran in June 2015.
Manual gas valve open. Checked 24V fuse. 24 volts at the fusible link, etc.
It's not the pressure switch, it was a problem in the past, and I knew to check it.
I don't here the 'click' of the gas valve opening. No smell of gas.
In the process of pulling out the manual!
I think it is using the igniter as the flame sensor and never been 'rectified'.
I plan on opening the side panel to see if the igniter is glowing.
Question - does the temperature sensor ever go bad? Is it a thermistor or a thermocouple?
Any other items to look at?
Thanks!
