TROUBLE SHOOTING
9.1
The motor, compressor and lamps are
dead.
-Check the main voltage and all electrical connections,
including switches.
-Check fuse in wall socket of mains supply.
-
Check the safety thermostat. See “Safety thermostat”
page 15.
9.2
Motor
is
not
running,
lamps
and
electronics operate (the motor turns freely
by hand).
-Motor overloaded. The motor protection may trip
because of mechanical overload. Reset the fuse by
pushing button on rear side of the motor housing.
-The motor capacitor is defective. Replace motor
capacitor inside the system.
-Malfunctioning wiring. Check wiring.
9.3
Compressor makes “clicking” noise
-Bath has been switched on and off to quickly. Wait
approximately 10 minutes before switching on again.
The clicking noise is a temperature fuse inside the
compressor preventing it from overheating.
-Clean the condenser unit and make free from dust. Air
must pass the inside of the unit freely.
9.4
Compressor will not start
When the machine has been switched off the pressure
in the cooling circuit can rise to a high level. For this
reason the apparatus has to settle the pressure of the
cooling liquid for a few minutes before it can be
restarted.
When this problem occurs more often it will indicate that
dust is blocking the condenser circuit. Clean the inside
of the TV4000LT / TV7000LT and remove all dust from
the condenser unit and fan with a vacuum cleaner. Do
not use pressurized air to remove dust. The flying dust
particles can damage the fan bearings, are very
unhealthy when breathed in and can lead to severe eye
problems.
