To light the pilot on a Teledyne Laars model, first ensure the gas supply is turned on. Locate the pilot light assembly, then turn the gas control knob to the "Pilot" position. Press and hold the knob while using a long lighter or match to ignite the pilot flame. Once the pilot is lit, continue holding the knob for about 30 seconds before releasing it; the pilot should stay lit.
The pilot light on a Teledyne Laars furnace is typically located near the burner assembly, often at the bottom of the unit. To access it, you may need to remove a protective cover or panel. Once located, the pilot light can usually be lit using a match or lighter after turning the gas control valve to the "pilot" position. Always refer to the specific model’s manual for detailed instructions and safety precautions.
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.
Check that you are getting voltage from the thermocouple. You should see about 600 millivolts.
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.
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
sit on it then throw it into a creepy cave
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
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.
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.
Have the thermocouple checked or spillage from down draft and make sure there is free air for proper combustion
Replacing the thermocouple that the pilot flame touches when it is lit will fix the problem 90% of the time. A thermocouple costs about ten dollars and allows the gas to the pilot and main tube to flow by generating millivolts from the heat of the pilot flame. The thermocouple is a copper wire attached by a small nut to the main gas valve near the pilot tube coming out of the gas valve.
Yes, a bad flame sensor rod could cause the Teledyne-Laars pool heater to shut off after firing for a short period. The flame sensor is responsible for detecting the presence of a flame; if it fails to do so correctly, the heater will shut down as a safety measure. Other potential issues could include dirty sensors, gas supply problems, or control board malfunctions, but the flame sensor is a common culprit for such behavior. It's advisable to inspect and clean or replace the flame sensor rod if necessary.
