It's marked as a 620 watt (wow) element.. and the wall lamp flickering would be about right (same circuit, 3rd floor of a house) for this load. Via some finagling, I've managed to turn the unit on and observe the glow of the header element. So thats still working. I switch the unit on, wait a few moments, and hear the familiar rising-pitch whirr as the motors spin a little. I see the bulb go on for a few seconds (no timepiece, I figure about 5 seconds). The bulb goes off for about 2 seconds, goes back on for 2 seconds, and then stays off until I cycle power and things start up all over again. Furthur suggestions (outside of taking it to my local service organization - yikes!) are solicited and would be appreciated. Mark P.S. My thanks to those who relayed the part numbers of the Service and CE manuals. +-----------------------------------------------+-----------------------+ | Mark Becker | .signature under | | Internet: mbeck@ai.mit.edu | construction | +-----------------------------------------------+-----------------------+
