It sounds as if the Thermocouple and or Thermopile are starting to fail. In which case they will need to be replaced. In addition, any obstruction in the exhaust vent or the fresh air intake vent will cause the heater to overheat and shut down and will not allow you to relight it, until it cools off.

Hope this helps you troubleshoot the problem.

Teledyne laars ES125 repair manual


The exchanger alone will run $600 or more, and the headers aren't cheap either. Best to replace the heater. I have had customers do expensive repairs (despite my objections) only to have other expensive parts (T-stats, gas valve, burner tray..) break soon afterward.

Jandy is the closest relative of Teledyne, they used to be affiliated. RayPak has been making reliable heaters for decades.

Unit dosn't seem to bve sensing flame. Clean your flame sensor. Its connected to your pilot light assembly usually. Its a metal rod that sits inside the flame. Could also be bad and need replaced. Hope this helps.

I have a Whirlpool gas water heater and the pilot light went out. When I light it it goes out as soon as soon as I release the RESET button.


if it keeps going out, its more likely the thermal coupling is bad and needs replaced. if the coupling goes bad it shuts gas of to heater as a safety precaution. it does not let any gas come out of the main regulator. it works on the principal when the end gets hot it opens the gas valve and lets gas through to burner. replace coupling. have a good day !!

The pilot light will not stay lit to light the heater.


The power pile (pilot generator) is defective. It produces a milivolt signal to ensure to keep the gas valve open. If it goes bad, the valve thinks the pilot is out, even when you are holding the button down, so when you release the button, it shuts the gas off to prevent excess gas buildup and a possible explosion.
