The PM code is
incorrect for
the QTS
Check the PM chip is correctly in place on the QTS board.
The QTS has a dedicated part number on the chip which is unique for each eikon
model.
Ensure the correct PM chip has been inserted to the QTS, an easy mistake to make
when both boards are replaced, don’t forget to transfer the PM from the old QTS to
the new QTS.
Loading of new up to date firmware is a must.
The PM code is
incorrect for
the SRB
Check the PM chip is correctly in place on the SRB.
The SRB has a dedicated part number on the chip, which is unique for each eikon
model.
Ensure the correct PM chip has been inserted to the SRB, an easy mistake to make
when both boards are replaced, don’t forget to transfer the PM from the old SRB to
the new SRB if replaced.
Loading of new up to date firmware is a must.

boards.
Can occur on
replacement of
either boards
and during
loading of
firmware.
Download the up to date firmware from merrycheftechnical.com
Load the latest firmware on to the oven using the autoup.ate file. Do not switch off
or interrupt until the oven starts to heat up, or the pre-heat selection screen is
displayed.
In the event of a continued issue, replace both personality modules (PM’s) and
reload the firmware.
Ensure there are no microwave leaks present around the control boards.
Cavity
thermocouple
damaged or
unplugged.
No
temperature
rise registered
for 10 minutes
during heating
Check that the thermocouple is correctly fitted and secure on to the SRB
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 SRB.
Check the error log. If the cavity temp reads 32767 (327.67
o
C) the sensor was open
circuit or not connected. A closed circuit will register the SRB board temperature
and will not generate the E111 error unless the oven has been heating for 10
minutes.

Check all the connections are in good condition and secure, from the incoming
power supply through the Filter, Fuse F1, SRB board and the heating element.
The heater element rarely fails, checking all of the connections first is imperative.
