I have an Electrolux Icon vent hood model E36PC75GSS in the condo I purchased 1.5 years ago. Unfortunately, a manual was not available when I moved in. The problem I have is the hood vent will start and then shut off and I see a "Delay Shut Off"message for a second before it shuts down. Also, the four lights on the vent hood flicker a bit. Can you please advise what the problem may be? Thank you. Rose Sayer, rosesayer@telus.net
