McDonald’s M2000 Computer Notes
The M2000 computer replaced the M100B in production units on 4/1/2002 in the U.S. and
on 6/1/2002 internationally. The M100B is no longer supported and no core credit is
available for out-of-warranty M100B computers. If an M100B computer still in warranty is
replaced with an M2000, a U.S. $50.00 core credit will be applied with return of the M100B
computer to Frymaster.
The M2000 is not a direct replacement for the M100B. It must be ordered as a kit,
826-1739 (Non-CE) or 826-1810 (CE), which includes a new bezel, speaker and other
mounting hardware. Previously published part numbers for multiple-computer kits are no
longer active. The computer in the kit works with either gas or electric fryers.
A 10 percent discount is available on the M2000 computer when a McDonald’s restaurant
replaces all existing computers with the new unit. The discount is available only on orders
of four or more computers and the computer order must be separate from other orders. It
must include the fryer serial numbers, store number and address in the body of the text.
The service M2000 computer, 106-0529 (Non-CE) or 106-2436 (CE), is designed to
replace an existing M2000 computer and does not include the retrofit mounting hardware.
These computers are not similarly discounted.

M2000 Programming Error
When all the programming buttons of a M2000 computer are not assigned products, some
M2000 computers will exhibit an odd failure. The problem occurs when an unused product
button is pressed before a cook channel button in a mistaken attempt to start a cook cycle.
The failure was caused by an anomaly in an automated programmer used to prepare the
M2000 computers. The programmer has been corrected and the problem eliminated in
computers built after 10/19/01.
When the odd button sequence is entered (usually product button number 5 is pressed
followed by a cook cycle button), the computer reveals the failure by displaying Low Temp
and continuing to call for heat. Pressing the temperature button will show a setpoint of 35°F.
Pressing the temperature button again will show the oil temperature rising above normal
setpoints.
Computers exhibiting this behavior should be turned off immediately.
Follow the procedure below to eliminate the possibility of the failure recurring. Also this
procedure should be followed when performing a start up on M2000-equipped fryers.

With each button’s LED illuminated, turn the computer off using the right ON/OFF
button.
The computer can now be programmed as described in the operational manual.
CM III.5 Computer Notes
In December 1999, Frymaster began manufacturing a new generation of CM III computers,
commonly referred to as CM III.5. From the operator’s perspective, there is no difference –
the computer looks the same and is programmed and operated in exactly the same way as
the original CM IIIs and is fully interchangeable with those computers, but there are several
differences that affect how servicers work with the computer.
CM III.5 computers are distinguished from CM III computers by the presence of a 4-pin and a
15-pin connector located near the bottom center of the computer back (see illustration
below). The factory uses the 4-pin connector to enter the parameter data for the specific
fryer the computer will be used on. It has no field use.
All CM III.5 computers have a label that shows the model number, item number (part
number), serial number, and CPU version number. Some CM III.5 computers have a second
label, as shown in the illustration. The second label is used when generic computers are
configured for a specific application. Always look for the second label and, if present, use the
Configured P/N number from that label when ordering a replacement computer.
Every computer has a data label showing the model number,
item number, serial number, and CPU version number.
Some, but not all, CM III.5-based
computers will have an additional
label showing the Configured P/N.
4-Pin Connector
15-Pin Connector
All of the previous programming procedures remain the same, but two new features have
been added:
1. If the display reads CALL TECH, the memory chip or its support circuit has failed. The
computer cannot be repaired in the field and must be returned to the factory.

2. A new code has been added. To determine the configuration of the computer when it left
the factory, press and enter code 165R. The software version number will be
displayed in the left window and the last four numbers of the computer part number will be
displayed in the right window. For example, a CM III.5 computer for an H50 full vat fryer
(8063706) will display 00.82 in the left window and 3706 in the right window. NOTE: The
version number and part number do not change if the computer is reconfigured in
the field.
Like the original CM III, the CM III.5 can be reconfigured in the field for gas or electric, full or
dual vat, and timer or controller operation. Various melt cycle times can also be specified.
However, the reconfiguration procedure is different.
To enter the reconfiguration mode, ground pin 8, press , and enter code 1656. (If using an
MTB310A test box, flip the TEST switch to the ON position to ground pin 8.) NOTE: This is
a sequential process; to leave a value unchanged, press to skip to the next step.
GAS will be displayed in the left window and either a 0 or a 1 will be displayed in the right
widow. 0 indicates the computer is configured for an electric fryer; 1 indicates it is configured
for a gas fryer. Press 0 or 1 to toggle back and forth between electric and gas.
Press . SPLt will be displayed in the left window and either a 0 or a 1 will be displayed in
the right window. 0 indicates the computer is configured for a full-vat fryer; 1 indicates it is
configured for a split-vat (dual-vat) fryer. Press 0 or 1 to toggle back and forth between fulland split-vat.
Press . CПtг will be displayed in the left window and either a 0 or a 1 will be displayed in
the right window. 0 indicates the computer is configured as non-controlling; 1 indicates it is
configured as controlling. Press 0 or 1 to toggle back and forth between non-controlling and
controlling.
Press . ACYC will be displayed in the left window and either a 0 or 1 will be displayed in the
right window. 1 indicates that the operator can bypass the melt cycle. 0 indicates that the
operator cannot bypass the melt cycle. Press 0 or 1 to toggle between enabling and
disabling the bypass option. (On full vat units, if 1 is displayed, the operator can press the
“R” button to bypass the melt cycle. On dual vat units, if 1 is displayed, the operator can
bypass the melt cycle on the left vat by pressing the “L” button and on the right vat by
pressing the “R” button.)
Press . C oП will be displayed in the left window and a number will be displayed in the right
window. The number indicates the number of seconds the melt cycle remains on. Use the
number keys to enter a new duration.
Press . C oFF will be displayed in the left window and a number will be displayed in the
right window. The number indicates the number of seconds the melt cycle remains off. Use
the number keys to enter a new duration.

Press . The changes to the configuration will be stored and the computer will be returned to
the normal operating mode.
Spaghetti Magic III (SMS III) Computer Error Messages
SMS III computers manufactured after June 2001 have two additional error messages:
FAIL indicates that the computer sensed grounding of the upper water level sensor
but not the lower water level sensor. That is, the cookpot filled with water, but
the lower water level sensor did not ground. Unless the low water level sensor
grounds, the equipment will not heat. To correct this problem, turn the computer
off, drain the cookpot, and clean the water level sensors.
SEND indicates that the computer sensed resistance (grounding) on Pin 8 of the 15-pin
connector. When the computer is programmed at the factory, Pin 8 is
temporarily grounded. If the shorting plug is left in place, or if Pin 8 is somehow
damaged, this message will appear when the computer is activated. To correct
this problem, check for a shorting plug in Pin 8 and remove it if present. If there
is no shorting plug, replace the computer.
