Question The other night we hooked up a new sauna. While running the sauna one of the kids started the washer and it tripped the circuit breaker. I reset circuit breaker but now I have no power to the lights fan in the downstairs living room. On the east wall of living room two outlets have no power and the downstairs bathroom light switch has no power. I removed and replace circuit breaker and removed and replace both outlets in the living room. I also replaced the light switch in the bathroom, but still no power? All other outlets work in the downstairs living room. I'm Puzzled

Answer Robert, I can't help to be curious about the addition of the sauna circuit and how it was installed. When something like this occurs, I always work the problem backwards starting with the most recent work that has been done and begin an inspection of what exactly was done and by who, and of course was it done according to code and inspected, with the GFCI for the sauna being tested. Once the sauna circuit installation has been verified to be ok, then a process of testing and inspections would need to take place starting at the electrical panel by a qualified electrician in order to find out exactly what the cause is.
