Appliances are like vehicles. They start depreciating as soon as you pull them from inventory. The power company is not going to replace a used appliance with a new one. They will make repairs.
You won't know what is involved until you have an appliance service person come to your home and assess the repairs. The repair person will be able to diagnose whether problems are control or mechanical issues. Power surges can affect computers, telephone lines and appliances.
Appliances should be plugged into grounded outlets. There are also power strips and surge protectors available.
