Jandy Lite 2 "lg"-

[omalley]

We purchased a used heater, a Jandy Lite 2 "LG"- 325000 btu Natural gas we are the second owners - it states it was manufactured in 2004, we hooked it into the plumbing no problem and with no leaks, same with the gas and Hydro, able to hook up no problems, Once everything was connected and turned on, it stated Normal operation, no problem codes came up on the screen, but basically it won't fire up, there is no code saying any sort of problem, The glow stick does not light up, nothing is trying to fire up! No noises to even state it is trying to do anything!! Looking for some help, maybe some ideas??!!

Thanks

were the power wires connect to the heater pc board there should be a little red led light lit. The little fuse also on that board could be blown. Thats a start. Next you will need a voltmeter to test voltage across the control circuit. Connect on lead to ground and then test the voltage at the fusible wires, pressure switch wires etc to see if you are losing voltage on the safety circuit

Good suggestions... also check the wiring connectors. Those heaters are notorious for the switch connections loosing contact.

Was the heater previously hooked up to automation?

the light on , fuse is good , ran the voltmeter across all circuits , starting with the flow,then pressure, ect. seem all good

She all good. connectors look fine no corrosion !

If the previous owner just cut the automation wire when removing the heater, it would have left the circuit open, preventing anything from happening when a call for heat came.
