After disconnected the 110 VAC from the device and the smoke cleared away, I dismantled the vent to get access to the Snorkel switch. I had a spare switch but realized the O-Ring was compromised. I got on the internet and ordered a new O-Ring from Appliance Parts. The part arrived very quickly and was able to complete the repair in a matter of days. Thanks to Appliance Parts, we are back in service.
