Error
Level
System
Response
E 101
Magnetron failed
to energise
Detects a magnetron
is not working
correctly
The current
measured by the
current sensing
transformer
was outside of
tolerance.
Failure of
component/s in
the microwave
circuit
Critical
Display error
message until
system is
power cycled.
E 102
Heater incorrect
current
Detects a heating
element is not
working correctly
The current
measured by
the sensing
transformer on
the SRB was <1A
when heating
cycled on or >1A
when heating
cycled off.
If some current
>1A, one or more
heater elements
could have
failed. If current
measured <1A
possible wiring
fault stopping
power reaching
element.
Critical
Display error
message until
system is
power cycled.
E 103
Ambient overheat
>70°C
Detects if the controls
area is operating
above temperature
The ambient
temperature
measured on the
BTS and SRB was
>70°C
Cooling fan failed.
Cooling fan
wired incorrectly.
Inlet air too hot.
Blocked inlet
filter.
Critical
Display error
message
until ambient

E 104
Magnetron /
Cavity Overheat
Detects if the cavity
and magnetrons are
above temperature
Cavity and
magnetron
overheat
thermostats
Cooling fan failed.
E103 / E106 not
triggering. Failed
SRB. Magnetron
failure. Wiring /
connection fault.
Blocked Inlet
filter.
Critical
Display error
message until
service call and
the magnetron
cools down or
the cavity stat
is reset.
E 105
Supply voltage
high / low
Detects if the power
supply voltage is
outside specification
The power
supply to the
oven voltage
sensor on the
SRB measures
too high / low
Incorrect
mains voltage.
Poor internal /
external wiring
connections.
Faulty SRB.
Critical
Display error
message until
system power
cycled.
E 106
Cavity reaches
25°C above
setpoint once
it has been
controlling at
setpoint
Detects if the cavity
temperature has risen
above limits
The setpoint of
the oven was
exceeded
Cavity fire. Failed
convection fan.
No impeller or
loose impeller on
convection fan.
Critical
Display error
message until
system is
power cycled.
E 107
Communication
error
No communication
can be made
between the BTS and
SRB
Loss of
communication
between the SBR
and BTS
SRB / BTS
connection cable
unplugged or
damaged. Faulty
BTS or SRB.
Critical
Display error
message until
system is
power cycled.
E 108 BTS PM error
Wrong PM found / no
PM found
The BTS or SRB
either has an
incorrect PM
(Personality
Module) fitted or
no PM is fitted
The PM has been
changed and is
incorrect. The
PM has been
removed.
