    Default Can't get Jandy heater pilot to light

    Hi, I'm new here. I have a Jandy pool heater and, can't get the pilot to light. I've replaced the pilot, thermal coupler, and pilot tubing.

    I'm not sure what else to check. Could it be something electrical? Is there a voltage I need to check?

    Any help you could give would be .... uh .... helpful

    It can be a bunch of things.

    Does the heater have a 120v electrical supply and a thermacouple, OR is it a millivolt heater with a thermapile. (Check the links, to see the difference!)

    Millivolt heaters are VERY sensitive to corrosion and have about a 1,000 connection points where corrosion can occur. I hated working on old millivolt heaters for just this reason.

    But there are other reasons why you could be having problems. The gas valve itself could be dead. Here's one people don't admit: Is the gas shut-off . . . turned off? Have you verified the presence of gas at the heater gas valve? If there is no flow AT THE VALVE, when you depress the pilot button . . . then the problem is at the valve or upstream.

    Be careful. People kill themselves working gas heaters. And they kill other people, later, by messing things up.
