[Elecraft] KPA500 fan won't shut off

[Jack Brindle]

That means the power is not shutting off. We bleed off the capacitor charge through the fan at front panel shutdown, which is why you hear the fan run for normally a short time. 
Turn off the KPA using the rear pane switch and call tech support in the morning. They need to look into this one.

The only way the fan stops running is if I turn the amp on with the front switch or if I shut the amp off by using the rear on/off switch. Menu setting for Fan is set to normal. Any ideas?
