TROUBLESHOOTING
Fault Code Troubleshooting
From Test Mode, you can run oven diagnostics and check fault counts. To access Test Mode see page
components for testing, adjustment, or replacement, see the Appendix.
Troubleshooting:
F1: BLOWER (Blower Running Status Bad)
NO
NO
Motor Windings Resistance Table
Replace blower motor.
Remove obstruc-
tion or if necessary,
replace blower
motor.
Do resistance measurements
between windings and
chassis agree with values on
motor windings resistance
table (below)?
Is the blower
motor spinning
freely?
NO
Is the Status Indicator
“A” backlit in
? (page “Test
Mode” on page 19)
NO
Replace the
BMSC.
To From Description Expected Resistance
Black Red Winding (A-B) 2.0-2.6 Ω
Black White Winding (A-C) 2.0-2.6 Ω
Red White Winding (B-C) 2.0-2.6 Ω
Black, Red, or White Green Windings to Chassis Open
NO
1. Disconnect control wiring (J1 connector).
2. Ground pin 5 of the J1 connector (Status
OK wire) to chassis to remove the back-
light from status indicator “A” (see “Test
Mode,” page 19 for more details).
Was the back-light removed from status
indicator “A” while pin 5 was grounded?
Check the wire
harness and if nec-
essary, replace the
I/O control board
(SAGE).
NO
Test for voltage on the J1 connector.
1. Ground pin 5 of the J1 connector.
2. While pin 5 is grounded, check the
J1-1 (red) terminal on the control
wiring plug for 0-10 VDC across pin
J1-1 and common (page 64) while
incrementing the blower speed in
.
Is DC voltage present throughout all speed
settings in on the J1 connector
Cycle power to the oven.
Did the blower start up?
Set the oven type
to Encore. Does
the F1 fault persist?
NO
NO
Is the oven type
set to “Encore”?
(see page 20)
Update the
oven firm-
ware.
