TROUBLESHOOTING
PROBLEM: FAN MOTOR DOES NOT OPERATE - (Continued)
Probable Cause
Motor start relay for 1/6 HP, 1700 RPM
split phase motor.
Relay K6 on relay board may not be operating
properly.
Relay board or control panel problem.
7-20
Corrective Action
Measure starting current through red wire. Be sure motor
is cool. Then close oven door. Starting current should be
approximately 7.0 amps peak dropping to o amps after 1.5
seconds.
Be sure oven is disconnected from branch
circuit power before performing any repair
work.
Current measured. Relay operating properly. Refer to the
schematic diagram (page 2-17) and check wiring harness
continuity between motor start relay and the motor.
Replace defective wire and/or wire terminal.
Current not measured. Replace motor start relay. See
page 2-17.
Check for line voltage between K6 contacts
(see page 2-17).
Line voltage measured. Turn off oven power and check
K6 relay coil continuity.
Line voltage not measured. Replace the relay board.
Coil has continuity. Refer to schematic diagram (page
2-17) and continuity check wiring harness.
Perform power supply check. See page 8-3.
