I have a Teledyne Laars model EPG 250 pool heater. I am having trouble with the pilot light staying lighted. I am able to follow lighting instructions to get the pilot light to light. The problem is the pilot light does not stay light no matter how long I depress the valve knob before releasing. I am guessing it is the thermocouple that needs replacing. What is best way to verify this? If it needs replacing, what advice do you have for making sure the correct part is used and making sure it is installed correctly. PS, not sure if this is important, but when I have pilot valve depressed when lighting, the pilot flame seems large. It has a flame that comes dorm the holes several inches back up in the gas supply tube.
Relighting the pilot light
Hi my name is Garry
Instead of a thermocouple, your heater has a Pilot Generator. The best way of verifying whether this is the problem is to measure it's output with a millivolt meter. Disconnect the Pilot generator form the Gas Valve, While keeping the knob held down to keep the pilot on, you should get between 600 t0 800 millivolts, to determine if the Pilot Generator is good.
Let me know what kind of output you are getting, and I can help you further from there. Thank you
Ok. Remember to disconnect leads from gas valve, so you can get a raw output reading. Will wait to hear back from you. Thank you.
Just checking back to see if you took the voltage measurements?
