We have an intermittent click somewhere in the kitchen. We are not sure if it is coming from an appliance or from a possible electrical problem. All appliances are electric and 2 Years old. The sound is a quick click. Then maybe a few minutes later another click. Then maybe 2 hours later another click. It happens when appliances are in use or not in use. Breakers are not tripped. We thought maybe the stove only because we have replaced the light in the oven 3 times in 2 years. I also have a scratch/crack on one of the smooth top burners. And it seems to happen maybe?? after stove or oven have been used. Don't know whether to call an electrician or appliance repair person. We also replaced the 2 gfci in the kitchen.
