Gas Pool Heater Troubleshooting

[ellry99]

Is this a millivolt (standing-pilot) or electronic-ignition heater? Did you light it or is it automatic when the heater calls for heat? This is the first information needed to help you with your problem. They each use entirely different systems and the troubleshooting is different. A brand and size would also be helpful.

Thanks for your response. My gas pool heater was installed in 1990. It is a Tropic Isle, millivolt heater. 400,000 BTU.

The output of the pilot generaor needs to be checked. It sounds like you may have a weak one. If it has not been replaced in 16 years you have been very fortunate. Your heater operates electrically, just using several hundred thousandths of 1 volt instead of 24 volts. The whole heater should be checked by a reliable service tech to make sure all the safey controls are functioning properly.
