租客发邮件说 the clothes dryer keeps tripping the circuit breaker,这个dryer是上个月刚从HomeDepot买的新机子,Whirlpool 7-cu ft Electric Dryer。我们直接给租客使用,delivery的时候测试过挺好的。没想到才一个月就出现这种问题。请教这一般是什么原因呢?需要请电工来看吗?谢谢!
烘干机一直让电箱跳闸是什么原因?
所有跟帖:
•
超负荷,请电工

有,breaker 不贵,大概$80, 但电工不知道,因您的panel 情况不清楚。找三个电工来估价就知道了。

Cannot just change the circuit breaker. Could cause fire.

问房客用干衣机时,是否同时也用其他电器,如微波炉等才跳闸,如果是,基本肯定是超负荷,而不是breake 坏了,如果不是也有可能。

电干衣机一般是dedicated circuit。反复tripped短路的可能性更大。
