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 does your teledyne laars phase 2 pool heater not ignite?

Possible reasons why a Teledyne Laars Phase 2 pool heater may not ignite include issues with the pilot light, gas supply, or faulty igniter. Check if the pilot light is lit, ensure there is proper gas supply to the heater, and inspect the igniter for any signs of damage or malfunction. Additionally, check for any error codes on the heater display panel that may provide further information on the issue.


What if my Laars 2 heater pilot wont stay lit when the button is released?

If your Laars 2 heater pilot won't stay lit after releasing the button, it may indicate a faulty thermocouple or a problem with the gas supply. The thermocouple is responsible for sensing the pilot flame and keeping the gas valve open; if it's defective, it won't allow the pilot to stay lit. Additionally, check for any blockages in the gas line or ensure that the gas is turned on. If troubleshooting doesn't resolve the issue, consider contacting a professional technician for further assistance.

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.


Where is the pilot light on laars mini therm 2?

The pilot light on a Laars Mini-Therm II is typically located near the burner assembly, accessible through a small inspection door at the bottom of the unit. To find it, you may need to remove the front panel or cover. Once located, the pilot light can be seen as a small flame next to the thermocouple. Always ensure proper safety measures are followed when inspecting or relighting the pilot light.

The water heater pilot can go out due to issues such as a faulty thermocouple, a dirty pilot light, or a lack of gas supply.


How do I turn on the water heater pilot?

To turn on the water heater pilot, locate the pilot light button or knob on the water heater. Turn the knob to the "pilot" setting and hold it down. While holding the knob down, use a long lighter to ignite the pilot light. Once the pilot light is lit, continue holding the knob down for about a minute before releasing it. This should successfully turn on the water heater pilot.


How can I determine if the water heater pilot light is out?

To determine if the water heater pilot light is out, locate the pilot light access panel on the water heater. Look inside to see if the pilot light is lit. If it is not lit, you may need to relight it following the manufacturer's instructions.


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
