I have a Kitchen Aid Superba double wall mount oven. There was a power outage today and when the power came back on, I got a F5 E1 error code. I tried cycling the breaker multiple times and it didn't work. After searching online, I replaced the oven latch on the upper oven because I assumed the code is related to the upper oven because when I press the "upper oven off" button the code disappears for 15 or 20 seconds, but then comes back. Replacing the upper latch didn't work and the code came right back after turning the power back on. I can hear a slight hum coming from the oven when off. Does anyone have any suggestions on what else can be the issue? Thanks for your help! Brian

Recently got a new LG fridge, and it's emitting a tone many times throughout the day. It's pretty low volume, but audible, and since I'm working from home about 10 feet away, I hear it every time and it's driving me nuts. And now that it's burned into my brain, I pick up on it even if I'm over in the living room with the tv on. I'm just concerned whether it's normal for it to be doing this, or whether something is wrong. It's a 5-second tone, and they happen randomly, sometimes twice back to back, sometimes separated by 10 or 20 or more minutes. But many times all day long. The tone is actually an E, an E4 to be exact - I've matched it to a tone generator. It seems to be some kind of pump cycling - right at the very end of the 5 seconds, you can hear like a motor winding down type of sound. You could maybe roughly equate it to the sound of a car's fuel pump priming when you turn the key to ON. The only pump I could think of would be the water pumping in new water after someone gets water or ice, but we're hardly using that at all, and like I said, it's just all day long. It's done it about 4 times just since I've been writing this. Anybody know what this might be, or if it's something I should be worried about?
