So our 10 yr heater ( jandy lite 2 ) seemed to have died recently. Since it was old we went new. Got a Jandy Legacy 399K BTU Digital Natural Gas Swimming Pool Heater LRZ400EN. After a brutal haul and installation it was up and running fine. 5 days of running fine. Then the system started to fail to light. It threw a fault code FAULTCHECK IGN CONTROL, but would after repeated attempts eventually light and run for hours. Looking in the manual it states that code is related to low gas pressure, or oscilating water pressure. Makes no sense. If the gas pressure was low , why would it run for hours. And the water pressure is consistent at around 14. The sales people want to rma , but it was a nightmare to install and move to the location , so I was hoping to troubleshoot before diving into a replacement which might encounter the same problem . The other thing that bothers me is the old heater worked fine, in a similar manner. If it lit , it worked great , but had problems lighting. Hope someone has some ideas as we're really lost as to the cause of the problem. Attached a pict of the installed unit
Thanks
