Hayward H4001 Heater Won't Start

ke7065May 28, 2008

Hello all,

Have a H4001D1, about 7 years old, using natural gas. Suddenly, I have no 'System Normal' light. It worked periodically, and then stopped.

I took covers off, and checked connectors. Found nothing loose. Operating the front cover interlock switch several times, I could get the blower to spin up a little, only to shut off again (click heard from ignitor assembly both on start and stop).

Any ideas where to start? Thank you in advance.
