How do you fix a bug zapper that lights up but dosent zap?

To fix a bug zapper that lights up but doesn’t zap, first, ensure it's unplugged for safety. Check the high-voltage grid for damage or debris; clean it gently with a soft brush. Inspect the internal components, such as the transformer and wiring, for any signs of wear or failure, and replace any damaged parts. If all else fails, consider consulting the manufacturer's guidelines or contacting customer support for further assistance.
