E111: Cavity
Sensor Failure
UI displays;
E111
Cavity Sensor
Failure. Please
contact your
Merrychef service
partner to
resolve.
Cavity
thermocouple
damaged or
unplugged
(open circuit).
Check that the thermocouple is correctly fitted and secure on to the IO board
connection X530.
If the thermocouple generates erratic values, or is more than 25
o
C out of range, it
will need to be replaced if the connection is in good condition and intact.
If the fault reoccurs after replacing the thermocouple, replace the IO board.
Check the error log. If the cavity temp reads 328
o
C the sensor was open circuit or
not connected. A closed circuit will register the IO board temperature and will not
generate the E111 error.

The oven
asked for
heating, but
did not reach
100
o
C within
30 minutes
Check all the connections are in good condition and secure, from the incoming
power supply through the Filter, Fuses F3 & F4, IO board and the heating element.
The heater element rarely fails, checking all of the connections first is imperative.
Ensure you counter hold the rear bolt of the element connections before tightening
the front nut on the element.
Lastly replace IO board
