Check Contact Sensor and wiring. If no problems are found
with Contact Sensor, replace Electronic Control Board.
Check Contact Sensor and wiring. If no problems are found
with Contact Sensor, replace Electronic Control Board.
Replace Electronic Control Board.
If motor runs continuously with power applied check for short
circuit across motor relay (RL2), or L1 applied to motor relay
output (J3-1) with cycle stopped. If motor does not start
when “start” key is pressed, check for open circuit between
L1 and motor relay connection (J3-2). If no wiring problems
found, replace Electronic Control Board.
Remove any load from dryer and check if drum turns freely
by hand. Check L1 power supply voltage, motor wiring, and
motor thermal protector (if motor thermal protector has
tripped, it may take up to 30 minutes to reset).
Check wiring. Check if Motor Centripetal Switches are stuck
in open or closed positions. Replace motor. Replace
Electronic Control Board.
Replace Electronic Control Board and retest.
Check for short circuit across heater relay(s) (RL5, RL6, RL7)
or L1 applied to heater relay output(s) (J5-2, J7-1, J7-3) with
cycle stopped. Check for open circuit between L1 and heater
relay connection(s) (J5-1, J5-3, J7-2). If no wiring problems
are found, replace Electronic Control Board and retest.
Check heater coils and connections for short circuits to the
cabinet. Replace heater and/or wiring and retest.
Check heater coils and connections for open circuits.
Replace heater and/or wiring and retest.
For Electric Model, check Inlet Thermal Limiter for continuity.
If Thermal Limiter is open, check for evidence of high temper-
ature event and any resulting damage. If no further damage is
evident, replace Thermal Limiter. If no problems are found
with Thermal Limiter, check exhaust vent system for air
blockages. If no problems with vent restrictions,
check/replace High Limit Thermostat, and retest.
Check Outlet Thermal Limiter for continuity. For Gas Model,
also check Inlet Thermal Limiter for continuity. If Thermal
Limiter is open, check for evidence of high temperature event
and any resulting damage. If no further damage is evident,
replace Thermal Limiter and retest.
Replace Electronic Control Board and retest.
Check resistance of Outlet Control Thermistor, and check
wiring for open circuit. Resistance should be between 4.9K
Ohm and 6.2K Ohm at room temperature (68-77° F or 20-25°
C). Replace Outlet Control Thermistor and/or wiring and
retest.
