Sorry for the loss of your mom's stove, but
If lightning took out the stove, she was lucky to have it. A manager from the GA Power Co. told me of a lady who had her house heavied up so that she could get an electric stove. The stove was still new and the only 220 volt appliance in the house when lightning hit the house. She was putting a blackberry pie in the oven when there was a big bang, the element went out in a big yellow flash and she dumped the pie upside down in the hot oven in her terror. She called, scared out of her wits, complaining about the stove. The power co. told her that if she did not have the heavy line to the stove to carry the charge from the lightning, the lightning would have probably set the house on fire.
