Help ID mystery sound in my kitchen
I also posted this in Appliances, but since you guys are my go-to source for all things, I hope you can help.
I keep hearing a sound in my kitchen that sounds exactly the way the toaster oven sounds on the Bake cycle -- when it cycles on and off. I was sure that I had left it on so I went to check it. Nope. Not on. Just to be sure, I unplugged it.
I am still hearing the sound! I unplugged the coffee maker and the coffee grinder. I stuck my ear up against the cabinet with the circuit breakers. That is not it.
It seems to be coming from the general area of the refrigerator, although the fridge is running fine. Everything is cold and the ice cube maker is making ice. I still hear that "electrical" sound (faint buzz) that goes on and off. It stays on for about 6 - 7 seconds. The fridge is a 10 year old Kitchenaid, side by side with ice and water through the door.
The other appliances in the kitchen are an OTR microwave, a GE Profile range and a Bosch dishwasher, all working fine. I presume it's not the garbage disposal.
Any ideas at all as what I am hearing? It's driving me nuts.
