The control module is the problem it allows the heater to come on then turns off power to the gas valve.if you are not getting enough water flow the high limit is turning the heater off then your problem is flow.

Clean your filter first, the water flow may not be strong enough to allow the furnace to stay lit.

Try jumping out the pressure switch on the heater. The pressure switch is normally closed, the water pushes it open. You can check continuity between the contacts on the pressure switch. Even a new switch will still cut the conenction

It sounds like your pool heater might have a defective controller (the part, not you). Check the controller and replace if necessary. It could also be that you need to cycle the ignition sequence until the air is out of the gas line. It could also possibly be that your gas valve needs to be replaced.

Laars-lite LD 97-2000 pool heater wont burn

cycling usually begins as the result of poor water flow caised by debris in the pump, dirty filter or low water level. once you have had some cycling the heater burners and ignitor become sooted and this requires pulling the burner tray, de-sooting the burners and pilot and reassembly. unless you are very competent you may want to call a service tech. Pool heater repair is a high laibility endeavor if done improperly. During the certification class our instructor showed us several houses that were burned down from improper heater repair.
