Fault Code Troubleshooting
From Test Mode, you can run oven diagnostics and check fault counts. To access Test Mode or turn on
Diagnostic mode, see page 18. To locate oven components for testing, adjustment, or replacement, see the
Appendix.
Troubleshooting:
F1: BLOWER (Blower Running Status Bad)
YES
YES
NO
Figure 83: Motor Windings Resistance Table
Replace blower motor.
Remove obstruction
or if necessary,
replace blower
motor.
YES
Do resistance measurements
between windings and
chassis agree with values on
motor windings resistance
table (below)? (Be sure to
check the blower motor.)
Is the blower motor
spinning freely?
NO
Are Status Indicators
“B” and “T” backlit in
 ? (page 18)
NO
Replace the
BMSC.
To From Description Expected Resistance
Black Red Winding (A-B) 5.9-7.3 Ohms
Black White Winding (A-C) 5.9-7.3 Ohms
Red White Winding (B-C) 5.9-7.3 Ohms
Black, Red, or White Green Windings to Chassis Open
NO
YES
1. Disconnect control wiring (blower = J1
connector).
2. Ground pin 5 of the J1 connector (Status
OK wire) to chassis to remove the back-
light from status indicators “B” and
“T”(see page 19, step 2).
Were the back-lights removed from the status
indicators while pin 5 was grounded?
Check the wire
harness and if
necessary, replace the
Sage control board.
NO
YES
Test for voltage on the J1 connector.
1. Ground pin 5 of the J1 connector.
2. While pin 5 is grounded, check the
terminals on the control wiring plug
for 0-10 VDC across pins 1 and 2 of
the J1 connector (see page 63) while
incrementing the blower speed in 
