Hello,

My name is Billy. This is generally a heat activated switch down by the burners. If the vent gets plugged, the heat exchanger...even high winds...can force the flame/heat backwards and trip this switch. Some are able to be reset others need to be replaced.

What unit do you have or do you have a picture of the burner area?

I'd you tell me what the burner manifold is
Customer reply replied 10 months ago
What's the burner manifold area?
Pool and Spa Expert: Billy, Technician replied 10 months ago

follow the gas pipe into the unit.....the gas pipe goes to a gas valve....from there it goes to burners

Pool and Spa Expert: Billy, Technician replied 10 months ago

great...that is gas valve...now pan out so I can see side to side in that area

Any luck?
Pool and Spa Expert: Billy, Technician replied 10 months ago

That is it....see the picture HERE

Yours is a one and done...meaning you will need to go to pool supply and buy a new one.

You can test for SHORT while by removing the 2 red wires and connecting directly together..

Pleas check for anything that could have forced heat backward like plugged vent pipe..

Just rate service to move off the active list (5 star system)

that's it? No easy fix here?
Customer reply replied 10 months ago
Will connecting them together do anything?
Pool and Spa Expert: Billy, Technician replied 10 months ago

This is actually the easiest repair...2 screws and 2 wires. No need to remove gas valve or wires from circuit board.

This is the easiest fix on the entire unit...connecting them together will work...BUT if the reason the flame backed out is still present you could overheat the front cabinet

Customer reply replied 10 months ago
Got it. I'll try connecting them together and see what happens
Customer reply replied 10 months ago
Do I leave them connected?
Pool and Spa Expert: Billy, Technician replied 10 months ago

is there another one like that on other side or just that one?

Ask Your Own Pool and Spa Question
Customer reply replied 10 months ago
Just that one
Pool and Spa Expert: Billy, Technician replied 10 months ago

yes they would remain connected....however I hope you understand I cannot instruct to bypass and leave a safety out of the wiring loop.

Ask Your Own Pool and Spa Question
Customer reply replied 10 months ago
No worries. I cannot even remove them without too much force so won't try
Pool and Spa Expert: Billy, Technician replied 10 months ago

They will eventually have to come off to plug onto new switch....they are slide on spade connectors...but with pool heaters are generally rusted and need pliers to work them off.

Customer reply replied 10 months ago
Okay. Thanks
Pool and Spa Expert: Billy, Technician replied 10 months ago

I wish you well on the repair...just rate service with the 5 star system to move off active list..

Thank you,

Billy
