Water heater won't ignite
I have a 6-year-old State Select Powervent pilotless water heater that is balky about igniting. It fires OK when I turn it off and on, but it sometimes won't ignite on its own. Is this an ignition module or ignitor plate problem I could fix myself? I'm familiar with mechanical repairs in general, just not water heaters. Thanks.
(Sorry if this a repeat question. My first attempt disappeared somehwere.)
