Blower goes off This condition may occur if a 115 volt Verify that the blower is actually a 115 or 5 minutes after the blower is wired across 230 volts. for loose wire.  Also, inspect the relay incineration cycle starts. determine whether the blower is actually across 230 volts.  If so, rewire to connect blower across 115 volts. System operative only while Reset timer inoperative. Rearrange wiring to make certain that foot pedal depressed. Replace timer otherwise.  First, lubricate gears, however.
