F) Motor Protector; G) Thermal Cut-Out - Panasonic MC-E4051 Operating Instructions Manual

F) MOTOR PROTECTOR

Motor
Protector
This cleaner has a motor protector by-pass valve which
automatically opens to provide cooling air to the motor
when a clog prevents the normal flow of air to the motor. If
the by-pass valve opens to prevent motor overheating and
possible damage to the vacuum, you will notice a change
of sound as air rushes through the valve opening.
CAUTION:
Do not block motor protector.
To correct problem: See the TROUBLE-SHOOTING
guide (page 14).
NOTE: The motor protector may open when using attach-
ments or when cleaning new carpet, due to reduced airflow
by the attachments themselves or by new carpet fluff filling
the dust bin quickly. See the TROUBLE-SHOOTING guide
(page 14).

G) THERMAL CUT-OUT

This cleaner has a thermal cut-out which automatically trips to
protect the cleaner from overheating. If a clog prevents the
normal flow of air to the motor, the thermal cut-out turns the
motor off automatically to allow the motor to cool in order to
prevent possible damage to the cleaner. During this time the
headlight remains on.
To correct problem: If this occurs, turn the cleaner off and
unplug the cleaner from the mains outlet to allow the cleaner
to cool and the thermal cut-out to reset. Check for and
remove clogs, if necessary. Also check and clean/replace
any clogged filters. Wait approximately forty (40) minutes
before switching on the cleaner. The motor protector will
not reset if the cleaner is not turned off even if the cleaner
has cooled down.
