Convection Fan Current Flow
Convection Fan – Forward – Low Speed
When the board selects a forward low speed, the K5 relay sends L1 through the K6 NC contact, then
straight into the motor. L1 is also sent into the 1st capacitor. K7 is not energized so the phased power
exiting the 1st. Capacitor has to enter the 2nd one. The phased current travels through the N.C. contact in
the K7 relay and out the REV terminal to the motor. The motor will run at Low speed (cw).
Convection Fan – Forward – High Speed
When the board selects a forward high speed, the K5 relay sends L1 through the K6 NC contact, then
straight into the motor. L1 is also sent into the 1st capacitor. K7 is energized so the phased power exiting
the 1st capacitor bypasses the 2nd capacitor. The phased current travels through the N.O. (now closed)
contact of K7 and out the REV terminal to the motor. The motor will run at High speed (cw).
