Model MP-941/942/943/944

3-6. OPERATION AND Setting Control to the Correct Number of Drawers

PROGRAMMING

(Continued) The different models, MP-941, 942, 943, and 944, all use

the same control board. The boards are programmed at

the factory for the correct unit. But, should the unit show

“E06” or some drawers will not heat, the board may not

be programmed for the appropriate unit.

The LED flashes at a fast rate for the drawer(s) not

programmed correctly.

To check the drawer programming, turn the unit off, then

back on. The display will flash the number of drawers

the unit is programmed for. If the unit is not programmed

correctly, follow these steps:

1. Turn the power switch off, then press and hold the

SET button and the drawer button, which corresponds

to the number of drawers that the unit has, and turn

unit back on, ex: MP-944=SET and number 4 button.

2. Release the buttons, and now the unit should be set

up for use.

Pressing and holding the drawer button shows the

temperature of that drawer. If no temperature is

displayed, the unit may need to be programmed by

the above steps.
