I bought a 10 unit apartment complex last year and i'm doing my own remodeling and repairs. I'm not a pro I just know a little about everything, lol! If you read my previous threads you'll see some of the issues I've already been facing and here's the latest one. Shortly after a tenant moved out I replaced all of the appliances and the new oven immediately blows the breaker but I don't know if the old oven blew the breaker too. How do I check the 220v wiring and breaker? I'm sure people buy brand new faulty appliances every once and a while but how common is it to end up with a LEMON?
