Question about Lite On Laars Lite 2 Heaters: 250,000BTU MV Heater

1 Answer

How do I access the thermocouple on my Laars Lite, LLD-400N

My pool heater lights then shuts off a few seconds. That could mean my thermocouple is defective or dirty. Cleaning it w/ steel wool sometime does the trick. I just can't figure out how to get to it.

Whoo told you it does the trick?The only trick I know that works on a thermocoupler is replacing it with a good one. It is the probe that sits in the pilot flame. If you take it out to scrub it, you may as well put a new one in its place . They are relatively inexpensive.

I have a Teledyne Laars Lite pool heater Model LLD 250N. When I turn the heater on it will run for 10 minutes and turn off. If I turn the power switch off and right back on it will run agin for 10 minutes...

It sounds like your pool heater might have a defective controller (the part, not you). Check the controller and replace if necessary. It could also be that you need to cycle the ignition sequence until the air is out of the gas line. It could also possibly be that your gas valve needs to be replaced.

Pilot light won't ignite.

One possible reason could be a bad thermocouple. This is a rod shaped device that is close to the flame. It's function is to turn off the gas if the pilot light goes out. Heat from the flame operates the thermocouple. When the flame goes out the thermocouple cools off and shuts off the gas. When one goes bad it will not let you light the pilot. Here's a picture of what one looks like. There's a bracket that holds it in place.f023fa6.jpg

Laars Teledyne Pool heater flames on for 2 seconds, shuts off

You have no flame rectification.....LLD series heaters check for a signal through the flame to ground; if the module does not detect this signal, it go through two more trials for ignition and then lock out the module. There should be a flame rod and it may need cleaning. I use steel wool.
