Appliance with semi-automatic defrosting

In some models defrosting is not controlled by automatic controls but the user
needs to initiate it by pressing the defrost switch located in the middle of the
thermostat switch. Restarting is done automatically by the thermostat. Its
assembly is almost identical to electromechanical thermostats with timers.
- The defrost switch is located in the place of the plug, in the middle of the
thermostat switch.
- It is pulled of together with the thermostat switch.
- It can be reassembled after pushing up the thermostat switch. The defrost
switch should be inserted in the bore of the thermostat switch and should
be pushed up onto the defrost pin in the middle of the thermostat shaft with
an approx. Ø5 cylinder pin.
Naturally, there is no defrost timer in these devices.
