Probable Cause
Corrective Action
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.
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.
WARNING
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
