Would a power outage cause the electronic control not to work and have to be replaced?
Answer Hello Doreen,
The electronic control contains a microprocessor chip. This is comparable to a home computer. Think of it like this, information is stored in a chip by holding "bits" of information. The information is stored either by 0 volts dc or 5 volts dc. Any strong fluctuation in the power supply to the home can disrupt and "scramble" the information. When this happens, the reaction of the microprocessor is completely unpredictable. If 5Vdc is where 0Vdc should be, the program is changed and the operation of the unit , if it operates at all, will be incorrect and possibly even dangerous to have plugged in.
I have found in my experience that control damage is more common in areas of brownouts. You see, when the voltage available drops, as per Ohms' Law, the current flow will increase by the same margin. Therefore, if the voltage drops by half, the current flow will double. The current flow is what wastes the board.
So, to answer your question simply, yes it can.
