Pull out the leads at temperature limiter

Check the continuity of the temperature limiter with
a multimeter.

Remove faulty temperature limiter.

Coat the new temperature limiter with heat conduct-
ing paste and install it.

After commissioning, press reset button

on the

control unit.

Checking the fuse/MCB

Fig. 66

Switch off the power supply.

Release the side closures and pivot the control unit
down.

Remove cover

Check fuse F1 (see connection and wiring dia-
