Motor Reversing (Spin) Relay - Microprocessor Models - Maytag LAT2300 Service Manual

3. Re-install coil wires (smaller termi-
nals).
4. Connect ohmmeter across larger
terminals.
If the washer fails to spin, check the
reversing relay.
RELAY WIRING
The following is a live voltage
check. Use appropriate care.
Unplug Washer Power Cord from Power
Supply.
1. Remove wires from reversing relay.
2. Measure resistance of relay coil (GY
to PU). Should show approximately
350 ohms.
An infinite reading indicates an open
coil and requires relay replacement.
3. Re-install coil wires (GY and PU).
4. Connect ohmmeter across RD to YL
on relay.

The following is a live voltage
check. Use appropriate care.
5. Program the spin cycle by pressing
the SPIN pad.
The relay should be energized and
the ohmmeter should show zero
ohms resistance (continuity). If
relay pulls in but ohmmeter does not
show continuity, relay contacts have
failed and the relay should be
replaced.
6. Relay does not pull in, measure DC
voltage across coil. If no voltage is
present, check microprocessor
board or wiring. If 24 VDC is meas-
ured, replace relay.
To Remove Relay:
1. Remove all wires from relay.
2. Remove screws securing relay.
Note: The relay has a tab which fits
through a slot in the control housing to
assist in mounting and location of the
relay.
Motor Reversing (Spin) Relay -
Microprocessor Models
The spin relay is a double pole, double
throw type switch. When not energized,
this relay is wired to run the motor for
agitate.

When energized, the relay contacts
reverse the start-winding connections
to the motor (blue and yellow wires)
and causes it to start and run for spin.
5. Program the spin cycle by pressing
the SPIN pad.
With the coi I energized the
ohmmeter should show 0 ohms
