While operating the AC window unit and a blow dryer, the circuit breaker tripped (this has never happened before and we have never had any electrical problems in general). After re-setting the breaker, the electricity in that one area of the house, has not returned. Does this mean that that actual circuit breaker is blown and needs to be replaced? We tried re-setting the whole house in addition to that one circuit. Nothing has helped. Please let me know what you think. Thank you!
