I'm trying to fix a half broken panini grill. The top right element was not heating up. I opened up the top casing, and found a blown connection, so I replaced the connection, and closed it up. Plugged it back in and popped the breaker. So I opened it again and saw one of my connectors was touching the housing, adjusted it and it got everything back up and running. Now when I turn on the right side the element on top just over heats and burns my bread! Is this likely a thermostat problem, or would there typically be a heat sensor for the temp controls in the unit also?
