TEMPERATURE CONTROL –
Interior cabinet temperatures are
controlled through the use of a bulb and
capillary type temperature control. The
control is located in the electrical box.
The sensing bulb is mounted on the
top of the evaporator coil on the 4060 and
4072. On the 5272 it is located on the rear
wall behind the evaporator coil. Be sure
to disconnect power supply prior to any
service work on the control.
The control is factory pre-set
between 19º and 21ºF for the GSVM4060,
4072 and - 26º to 28ºF on the GSVM5272 to
maintain between 35º and 40ºF interior
