PWR alarm beckman l8-70m
When we turn the unit on an alarm sounds and a PWR message flashes.
Alarm sound stops. Vacum and temp settings work.
What is this alarm about?
Also, the power switch does not always turn on. May require you flip it on 1 or 2 to get pwr.
The STOP signal and beep are usually accompanied by another message.
If you send me your e-mail address, I'll send you the Troubleshooting pages from the User Manual for the L8-70.
Hope this will help you.
This is indicative of a defective power circuit breaker. The breaker, over time, will get "spotty" and not make a good solid contact. The beeper indicates that a power failure has occurred and less than 30 seconds have elapsed since the power was re-established.
Remove and replace the circuit breaker (not easy as the console and all in it must be removed first.) The Airpax part number should be printed on a label on the side of it. Replacements can be ordered from www.onlinecomponents.com
