Pool Heater Won’t Ignite

Pool Heater will not ignite. Teledyne Laars Model LLD175N-C

The electronic ignition “coil” does not glow when the heater tries to start. Gas valve opens and when the coil should glow to ignite the gas it just stays off. I have replaced this ignitor in the past. I’m wondering if there is possibly something else that may cause this. It was working fine a few days ago then just quit. I can replace the ignitor myself if you think that is the problem. I spoke to your Parts Department and they can order the ignitor. Part number R0317200.

Thanks for any info you may provide.

  1. Greg if you have proper voltage at your black/yellow wire of the ign cntrl mod you would want to do a resitance test on your ignitor when it is cool to the touch. If the ignitor checks out you may have a bad ign cntrl mod. If not you may have a bad ignitor. If you don’t have proper voltage at your black/yellow wire of the ign cntrl mod check that your temp board is calling for heat. Do a resistance test on your thermistor. If it’s within proper range you could have a bad Temp board. If not you could have a bad thermistor. If all else fails contact our Service Support Desk to book a diagnostic and repair of your Teledyne Laars pool heater.
