Troubleshooting

Hotplate & Magenetic Stirrer 7-1

Thermo Scientific

Electrical Problems

Cause

Corrective Action

No power

Unsuitable power supply

Meet the electrical requirements of this instrument before use.

Power cut-off by a circuit

breaker or power blackout

Find out why blackout or cut-ff happened and restore power. If

there is a short circuit or leakage, trace the source of the prob-
lem and fix it.

Loose power connection

Reconnect the power cord firmly to the power outlet as well as

to the power socket at the back of the instrument

Damages in power cords,

power outlets, or plugs,

Replace the damaged part with a proper one.

Internal circuit failure

Contact Thermo Scientific for service.

Repetitive tripping of circuit breaker

electrical overload

Disconnect all the appliances connected to the breaker first and

reconnect them one by one to find the reason for the overload.

Internal circuit failure

Contact Thermo Scientific for service.

No operation with power on

Power cut-off by built-in

overheat prevention circuit

If the main body is overheated, the built-in overheat prevention

circuit stops heating to protect the instrument.
In such cases, let the instrument cool down for some time
before power reconnection.

Internal circuit failure

Contact Thermo Scientific for service.
