Wash Basket - Maytag MFS25PN Service Manual

mounted to the shell front. SQ 1 is in series
with the current overload protectors on the
contactors and the thermal overload circuits
in the motors. If these series circuits are
closed, there is continuity from J4.1 on the
control board to J4.6 on the control board,
supplying current for RL20 on the control
board. Refer to the wiring diagram of the
machine for help in understanding the door
closed switch circuit.
At the start of a cycle, RL8 on the control
board closes and supplies current to the
bridge rectifier GU2, which converts the 208-
240 volts A.C. to D.C. voltage and powers the
door lock solenoid. With current on the door
lock solenoid, the plunger is drawn into the
solenoid, pulling the gate downward and
allowing the link to rotate and the pin in the
link to drop into the notch on the gate acti-
vating. The rotation of the link also activates
SQ2. The gate is latched downward by the
spring connected to it and the pin in the link.
With the gate latched, the cam is blocked and
prevents the door from unlocking in the case
of component failure or power loss.
At the end of the cycle, RL 18 is switched off
and RL 16 is switched on. RL 16 supplies 208-
240 volts A.C. to bridge rectifier GU 1, which
supplies D.C. current to the door unlock
solenoid, rotating the link, disengaging the
pin on the link from the gate and opening
SQ2. With the gate upward, the cam rotates
back to allowing the door to be opened.
Note: At the end of the cycle, the display on
the control board shows "Unload Now" and
D.C. current is applied to the door unlock
solenoid until both SQ 1 and SQ2 are open.
With the door both unlocked and opened the
display changes to "Select Process".
WASH BASKET
Removal:
There are two designs used in the MFS
models: MFS25, 35 & 50 (basket shaft is
welded to the basket) and MFS75/80, MFS90/
100 and MFS125 (basket shaft is detachable
from basket)
On the smaller machines, the cabinet must be
removed from the machine to gain sufficient
access to the shell assembly to remove the
basket, backplate and bearing assembly.
1. To remove the cabinet disconnect and
lock out all power to the machine.
2. Disconnect the water service and drain
connection.
3. Remove electrical power connection
wiring from the machine at the service
disconnect switch.
4. Open top panel, remove the back panels,
and remove side panels.
5. Disconnect drain hose, fill hose, vent
hose, and water level hose from shell.
6. Disconnect motor wiring and door lock
wiring harnesses.
7. Remove lower front panel. (Remove
screws at bottom of panel and lift up on
panel)
8. Remove fasteners on lower panels and lift
cabinet.
9. Remove counterweights from upper part
of shell assembly.
10. Remove basket pulley.
11. Remove fasteners at front of shell that
attach shell to front plates.
12. Remove fasteners on the three brackets at
the rear of the shell that fix the shell to
the lower section of the machine.
13. Remove the shell from the lower section
of the machine ..
14. Remove the fasteners on the backplate
assembly and lift the basket, bearing
assembly and backplate assembly from
the shell assembly.
15. Remove the bearing assembly from the
basket shaft, separating the bearing and
backplate assembly from the basket.
