Maybe your filter needs to be cleaned. WHen was the last time?
you have a bad heater core
A pool heater typically uses either gas or electricity to generate heat, which is then transferred to the pool water through a heat exchanger. The heated water is circulated back into the pool to raise the overall temperature. The heater can be adjusted to maintain a desired temperature setting for the pool.

Heaters are usually plumbed in after the filter. The pool filter/pump is what circulates the heated water. Ans: The heater will not work or fire if the pump is not running.
If your Laars Lite 2 pool heater isn't igniting when set to spa mode, first check the gas supply to ensure it’s turned on and the gas line is clear. Inspect the pilot light assembly for dirt or clogs, which may prevent ignition; cleaning it can help. Additionally, verify that the thermostat is set correctly and that any safety features, like the high-limit switch, are not triggered. If issues persist, consulting a technician may be necessary for further diagnosis.
