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

1 Answer

Laars Lite 2 Heaters starts up (ignites) and shuts down in 2 secs

Basically, the fans start spinning, the gas flows, you can hear it light and then it just shuts down. This happened before and my old pool guy replaced the pilot and it worked for a year. My new pool guy cant figure it out. ANYBODY PLEASE HELP!

We have a laars lite 2, when we openned the pool


Thank you for posting your question here on Fixya.com.

It could be...does it open up at the point the heater shuts down? Check it with a DMM to see. It is more likely an issue with flame recognition off the pilot/ignitor. Check them for rust that would cause a faulty connection.

PILOT LIGHT WILL NOT LIGHT


the thermocouple not only keeps the pilot on but lets the gas valve know its okay to open on a call for heat, remove your thermocouple and clean it with a fine grit sandpaper and if this doesn't work replace it all together.

Laars lite 2 Spark egnighter will not spark


turn power off first. I would disconnect igniter wire which will be a thick orange wire that comes off of ignition module if it is spark. once you have that the end will look like a spark plug wire take shield away from metal then hold orange wire in hand close but not touching metal turn power on and it will take a couple of minutes before it should start sparking. If you don't see a spark then it is most likely the ignition module. There should be a red light on ignition module that will blink to tell you what the failure is if is is a newer on. When you turn power on to laars light 2 the inducer motor should come on then a pressure switch should send 24volt to gas valve for pilot to lite.Can you smell gas at all when laars should be igniting. If you have any questions fell free to email me back
