We have a laars lite 2, when we openned the pool


Thank you for posting your question here on Fixya.com.

It could be...does it open up at the point the heater shuts down? Check it with a DMM to see. It is more likely an issue with flame recognition off the pilot/ignitor. Check them for rust that would cause a faulty connection.

VN18TB PILOT LITE GOES OUT STAY LITE TILL HEATER COMES ON AFTER THE HEAT RUNS AND TURNS OFF THE PILOT LITE SHUTS OFF NATURAL GAS VANGUARD


Sounds like a weak thermocouple. With the extra heat of the main burner running it can keep the pilot solenoid open...without it it fails shut. Try replacing the thermocouple. (small rod the pilot flame burns against with a skinny copper tube going to gas valve).

Gas water heater wont keep lite my gas water heater keeps shutting off and has to be restarted pushing the 2 button iginition


If your water heater is a sealed burner type with the poush button ignition(piezo) then the problem could be with the secondary air intake screen under the water heater. It will be located inside the compartment under the water heater. This is where the gas burner gets combustion air. If that screen gets clogged with lint or dust this can cause the water heater to keep shutting off. You will need to use a air compressor and completely blow out that coimpartment and screen as best you can. Also be aware that if you have a Whirlpool water heater they had a problem with the gas control valves on these and it might be covered under a recall. Call the number located on the water heater to find out further information.

Circulating pump shutdown piolet lite shut off on boiler


It sounds like you have a circulation problem. The bleed off valve should only open when you have a presure problem (nonexistent on the open system of a pool) or when you have a over herating problem witch will shut down your pilot also. Check your heater by-pass valve. (A valve in an "H" on the inlet and outlet of the heater) This should be 80-90% closed to force water through the heater. If not this the standered; check the baskets, clean the filter and make suree there is enough water to keep the pump primed. I hope this helps, if not send more info on what is going on.Good luck.

Heater does not stay running shuts down may or may not come back on


I hope your pool heater is still running! Anyway you mentioned that when you reinstall the heater door the heater turns off.

This is my personal experience with this; there is no switch on the door, keep that in mind; so ask yourself: when you remove the door are there any wires touching or resting against the inside door panel?

if so its possible that one of the wires in a connector is broken, the crazy thing is you cant see the broken wire that is causing your intermittent issue.

What I did was cut off all of the wire connectors and installed new ones, now the heater is running like a champ.

Good luck
