Good chance its your hot surface ignighter that has broken. Check to make sure that there is 120 v or far more common 220v at fenwal Depending if heater is wired for 120v or 240v. If proper voltage is present ignighter is broken. by zoomy

What if the pilot on your teledyne laars epg 250 pool heater will not stay lit and you have just replaced the pilot generator?
Check that you are getting voltage from the thermocouple. You should see about 600 millivolts.
Why would burner pilot light extinguish shortly after firing up on Laars Lite Model LLG Pool heater?
Have the thermocouple checked or spillage from down draft and make sure there is free air for proper combustion
How do you short the control circuit manually on a teledyne-laars pool heater?
First of all, I'm assuming that your heater has a pilot and not self ignition. You will need a jumper wire ( 16" of wire with an alligator clip on each end) attach one end to the terminal on the gas valve that the red wire from the pilot generator is connected to ( pilot gen. is the thing the pilot flame touches). Now attach the other end of the jumper to the terminal where the wire from the connects to the knob where you set the water temp). NOTE: JUMPING BYPASSES ALL BUILT IN SAFETY DEVICES AND IS FOR TEST LEAVE THE JUMPER CONNECTED TO RUN THE HEATER FOR HEATING PURPOSES!!!!
Why won't your laars lite pool heater turn on The heat exchanger temperature sensing bulb and siphon loop assembly have all been replaced with no leaks.?
When was the last time the filter was cleaned? Have all the components in the heater system been checked for proper values? Does the heater sound as if it wants to fire up? Does it have a pilot light or electronic ignition? Have the orifices been checked for bugs or spiders? Ken
Is the pilot light bad when it produces 200mv at the maximum temperature setting but won't start the burners on a Teledyne pool heater?
I was told by Teledyne Laars that your pilot generator needs to produce at least 500mv to open the gas valve. Mine makes 350mv and will not open the valve. Hmm, I think that should be nearer to 600 mv - 700 mv.
Why would a Teledyne Laars heater thermostat allow you to light pilot light but not allow you to turn it on?
Have you rotated the gas valve knob to "run". Have you turned up the thermostat? Is the pump running? No pump water flow - no heat -- no filtration. Is the filter clean? When was the last time you cleaned the filter? Ken
Is the thermocoupler bad if a Teledyne Laars series 1 EPG 250 pool heater pilot light ignites and burns high but does not light the burners?
It could be it. The pilot generator may be weak. The Valve could be defective. The High limit or other safties could also be defective. Could be corrosion on the connection. could be a water flow broblem. could be a weak flame
What is wrong if your pilot light will not stay lite?
High winds, pilot generator. Is the heater located next to a wall? Is the heater door closed? Does the heater have a draft hood or what they call a stackless heater? Ken
What should you do if the pilot light won't stay lit on a Teledyne Laars pool heater and the pilot generator registers up 500 MV?
From what I have read, 500mV is not enough to keep the pilot light lit. Here is what I read on a different site: "You can check if this is the problem by measuring the voltage on the wires coming back from the pilot. When you have the red switch depressed, check the voltage (should be about 200mV). If there's no voltage, then change the thermocouple. The thermocouple will generate up to 750mV in a pilot flame. If it falls below 550mV it should kill the fuel source." Hope this helps.
Hot water heater pilot light works heater wont light?
Have you turned the control from Pilot to On? Have you increased the temperature setting?
Why water heater pilot won't stay on?
Thermocouple. Keep pilot knob depressed for 30 seconds after lighting pilot.
What could be the problem if a Teledyne-Laars pool heater's pilot light was lit with no problem the valve is 'ON' but the burner does not start up?
The database did not find the text of a page that it should have found, named "What could be the problem if a Teledyne-Laars pool heater's pilot light was lit with no problem the valve is 'ON' but the burner does not start up". This is usually caused by following an outdated diff or history link to a page that has been deleted. If this is not the case, you may have found a bug in the software. Please report this to an administrator, making note of the URL. On the inside of the heater cover, and within the documentation shipped with the heater, there should be a diagram of the control circuit. These heaters will not operate if the pump is off (pressure switch), if the "fireman" switch is off (a switch generally inside the pump timer that disables the heater about 15 minutes prior to turning off the pump), nor if both of two additional high temperature limit switches are activated (models will vary). The fact that the pilot is lit indicates that the pilot generator is OK. If you can turn the burner on by shorting the control circuit manually (using a jumper wire) the problem is in one of the safety limit switches or in the thermostat itself. Also, when was the last time the filter was cleaned? k
