mine has done the same thing, when the temps hover around 110
and the park gets a little rolling brownout going on. Nothing I can
do about it living in the desert but it becomes quite a fear when I'm
at work and the dogs are inside, and the circuit breaker trips. It has
happened only a couple times and luckily my two girls were fine.
Getting close to retirement though
and I can leave the heat of
the summer behind me.
