[Elecraft] KPA 500 Fan Continues to Run

[Bill Gaines]

With the amp and rig turned off the fan in the KPA500 continues to run. Not just the short interval I was used to it running, but for days it will run. It stops when I turn the amp on and into standby. Any ideas? Did I somehow change a setting somewhere or has something failed? Unplugging the amp then plugging it back into the mains did nothing to stop it either.
