Yoder640 shows 350 at start but shows temp is decreasing

My Yoder 640 (bought in2016) on Thanksgiving was working fine at 300 degrees for 2 hours then temp started showing it was going down but still showed 300 on control panel. And it wasn’t heating then it blew the circuit breaker on the plug in receptacle. I turned off and tried it next day and it started and showed 350 start up but the lines showed it was going down instead of up. Then it tripped the circuit breaker again on the plug-in. Is this a thermocouple problem or a control panel problem or something else?
