OPERATING ISSUE
RECOMMENDATIONS
Dryer does not
turn on.
1. Check power to unit and connections. Verify dryer is receiving voltage
at terminal block.
2. Check RED service LED light for the following:
A. Light is ON: Place hands under sensor. If light stays on, then
replace sensor. If light goes off, check to make sure wiring is
correct at dryer control. If OK, check motor fuse, if so equipped,
and wire connecting to motor. If both are OK, replace motor.
B. Light is OFF: Check for loose, disconnected or improper wiring at
dryer control (see wiring schematic affixed to blower housing) or
replace
dryer control.
C. Light is FLASHING: Dryer is in lockout mode (adjust sensor range):
• If dryer will not turn on, stays on, or stops working, it may be
mounted too close to a counter or object and has gone into
lockout.
• If relocating appliance is not possible, adjust the range of
the sensor by turning off power to dryer. Then turn the range
adjustment on the control board counterclockwise towards L (-)
low to decrease sensor range.
