Hello all,
I have a Laars LT low nox pool heater (>2003 model) - heater won't work.
Between myself and one pool serviceman troubleshooted the heater but still can't figure out what is wrong. Perhaps someone can help!? Here is the issue:
We followed the following appropriate manual (see link) on page 16 and 17 --- http://www.victormfg.com/_build/docs/prodguides/JandyPoolHeaterTroubleshootingGuides.pdf
(this is the laars LT low nox pool heater troubleshooting manual)
steps 1, 2, and 3 are fine
step 4 - fan is on, yes.
says skip to step 5.
step 5, yes, working (24 vac purple wire at both ignition and ignition control terminal are fine)
step 6:
hot surface ignitor glowing? No.
turned power off - ohm test 60 ohms - confirms working
which suggests ignition control is faulty.
I purchased $200 exact model and replaced. However, still NO change.
I turn on for heat - and fan turns on, I hear click, gas turns on... but again, burners do not turn on and it recycles these steps x 3 and then turns off.
So... I then (just in case) replaced the HSI (hot surface ignitor) with brand new one.
Again, NO change in above pattern.
I nor the pool serviceman was able to find a 'short' anywhere.
Any suggestions please??
Thank you!!!!!!
