Nothing else was running on the circuit. It is a 20 amp gfci that I installed for patio fans and under eaves for Xmas lights. Nothing was running. Changed fuse and plugged directly into same outlet and 400° for one hour went fine. Not sure what internally caused fuse to blow.
I just checked fuse with multimeter and get no reading although it appears in tact. Going to get a new fuse and try again. I was using a 12 gauge 15ft cord and did not try a non gfci. I was getting some smoke to box, but then it tripped.
RT-590 delivered and assembled yesterday. This morning during initial burn to 400°, temperature got to 75° and tripped gfci breaker. I reset, circuit fine and outlets fine. Now no power what so ever on grill. Calling Recteq tomorrow, just wanted to see if anyone has suggestions to look at...
