Service / Repair
It is unlikely that you will need to service or repair your machine for many years. In the event that you need
to replace either the temperature regulator or the heating element, it is a very simple procedure to open the
machine and replace the relevant parts.
ELECTRICAL DIAGNOSTICS AND REPAIR MUST BE PERFORMED
BY A SUITABLY QUALIFIED PERSON.
Electrical Troubleshooting
The suitably qualified person must refer to the wiring schematic section before attempting diagnostics or
repair.
The following is a functional summary of the electrical control circuit.
Power is supplied at the C14 Inlet receptacle (SKT1). Both power feeds (L&N or L1&L2) pass through the
2 pole power switch (S1), this switch is illuminated when power is present. Power is fed from the switch to
the heat power regulator (R1) and process timer (T1). The process timer is a standalone function. The
heat power regulator provides a rotary variable output to the quartz heating element (QE1) and the power
indicator (IN1). The Quartz Element is fitted into the 2 lamp sockets (SKT2).
There are several possible fault scenarios. Apply a methodical approach when diagnosing.
For power problems there are basic indicators that will assist with diagnostics; if the switch indicator is on
then this confirms there is power to the machine. If the Power switch indicator is OFF then the problems lies
before the switch (power lead or input fuse). Also if the timer shows ON then there is power to the machine.
If there is no heat output then inspect the heat element and filament. Check if the output indicator is ON
or OFF etc.. To gain access to the element and electrical components remove the button screws from the
bottom panel and the small countersunk screws from the side panels.
Fault scenarios may also be caused by poor connections. Check all the connections. Also check the heating
element is inserted correctly into the lamp holders (SKT2).
Use a multi-meter to check the lamp continuity if required. The correct resistance reading for the Quartz
heating element is 65 Ohms.
AFTER ANY MAINTENANCE WORK ALWAYS CHECK AND VERIFY THAT THE EARTH
CONNECTION IS CORRECT.
If you are unable to resolve any problem relating to your machine, or if you wish to order spare
parts please contact us at the below address, stating the model (FLB1000) the serial No. (on
specification plate) and a full description of the fault or parts required.
