The furnace operation seems OK, but lately I'm hearing a noise that concerns me. It's an "electric" humming sound about 20 seconds long, ending with a click that sounds like a relay dropping out.
It seems to be random, meaning that I can't relate to the burn-blower cycle, only that the "cool-down" (?) blower cycle is about the same 20 seconds in length.
Thanks for any suggestions on this.
