Maytag MDE17CS - Gas Dryer Troubleshooting Steps; Troubleshooting Dryer Not Shutting Off

6-8
• On MN models visually check the
terminals on the Cycle Selector Switch. If
the look OK, select Whites and Colors then
remove the wire from the P terminal and
check for continuity (0 Ω) between P and
WH. If not there replace Cycle Selector
Switch. If continuity (0 Ω) is found replace
the timer.
GAS DRYER:
Unplug dryer or disconnect power.
Locate the red wire at the gas valve and the
red wire on the thermal fuse that is coming
from the control, remove this red wire from
the thermal fuse and check resistance
from the bare terminal on the thermal fuse
to the red wire at the gas valve. it there is
continuity (0 Ω) then skip to step 8.
Remove the service panel to access the
thermal components.
Perform TEST #3a. If the thermal fuse is
OK, go to step 5.
Check both operating t/stats by removing
one of the wires on each of the t/stats and
checking for continuity (0 Ω) across both
terminals of each operating t/stat. If an open
circuit
(infinite Ω)
is detected, replace that
t/stat.
Perform TEST #3b. If the high temp cutout
is OK, go to step 7.
Locate the high temp thermostat. Remove
the wires from it. Measure the continuity
through it by touching the meter probes on
the bared terminals.
• If there is an open circuit
(infinite Ω)
,
replace the high temp thermostat and high
temp cutout as a set.
• Otherwise, go to step 8.

Perform TEST #3c (Gas Valve Test). If
this is OK, replace the dryer control board
on stack dryers. On CS models check the
Heater Bypass switch (B) on the timer.
On MN models check timer switch #2 for
continuity (0 Ω) with the timer turned to any
time other than off. If either switch shows
open replace timer.
Dryer will not shut off:
Unplug dryer or disconnect power.
Check for excess cycles loaded on the timer
by rotating the timing gear. Both timer arms
need to move when the timer clicks in order
to be clear of cycles. (See page 4-14)
Access the dryer mechanical timer, and
measure the voltage at the timer motor.
• If there is 240 volts at the timer motor,
check the timer motor terminals.
• Timer motor terminals OK, replace the
timer.
