Vibration Switch Adjustment And Function Test - Maytag MFS80 Installation Instructions Manual

Vibration Switch Adjustment and
Function Test
The Vibration Switch is a critical component of the washer that
avoids washer damage during extraction with an unbalanced
load. Vibration Switch adjustment must be performed during
installation and checked annually, and should only be done by a
qualified technician.
Models MFS80, MFS100, and MFS125: The Vibration Switch is
on an assembly bolted to the bottom of the mounting plate (4).
The switch controlling element is inserted into the rubber bushing
(3) located in the limiter (2). The limiter is bolted to the drum front
face (1). The switch attached to the mounting plate is a part
of the washer frame, which is attached to the limiter with the
bushing. The bushing is the part of the assembly that vibrates.
Models MFS180, MFS230, and MFS275: The vibration switch
has a flexible controlling element. The element is attached to
a holder (6) by nuts (5). The entire assembly is bolted to the
washer frame (3). The switch controlling element is inserted into
the limiters (2), which are bolted to the drum front face (1). The
limiters are the part of the assembly that vibrate.
For all models, the bushing adjusts the sensitivity of the vibration
switch by controlling the unbalance level of the wash load in the
drum.
Vibration Switch Adjustment
1. If the washer was just installed, run the washer through one
complete extraction cycle without a load so the drum is at its
balance point.
2. Turn off power to washer at the circuit breaker or fuse box.
3. Open the control panel cover.
Models MFS80, MFS100, and MFS125:
4. By moving the vibration switch on the holder to the left,
you will increase the sensitivity; to the right, you decrease it.
It is necessary to keep the distance of 4" (100 mm) between
the limiter (2) and the vibration switch (5). See the Side View
below.
5. Moving the holder (7) with the switch left or right will center
the switch control element in the limiter's rubber bushing.

4. By moving the vibration switch on the holder to the left,
you will decrease the sensitivity; to the right, you increase it.
It is necessary to keep the distance of 2.36" (60 mm) between
the limiter (2) and the vibration switch (4). See the Side View
below.
5. Moving the holder (6) with the switch left or right will center
the switch control element between the limiters.
