I have a stacked combo unit (I guess the call them Laundry Centers) that is giving me problems. When I run the dryer it will run for a short period of time and then trip the circuit breaker. I ran it on low temp. setting and I could feel heat in the drum. I also noticed that the circuit breaker was getting warm to the touch as well. This unit is in a rental unit of mine and the tenant stated that on the high temp setting it trips in about 2 minutes and the breaker gets really warm. I am assuming that it is either the heating element open to ground or the high thermostat is faulty. The accessibility with this machine is limited. I would prefer to be proactive and replace multiple parts to keep me from having to disrupt my tenant with future repairs. Any recommendations on parts to replace. Thanks,
