DOOR OPEN appears on display when the storage door remains open, during operation, for longer than the
time set by i2
The minimum temperature reached by the cabinet is recorded in the Service menu, under HACCP
An extended door opening beyond the time set by parameter i14 activates the defrost
Found the cause of the problem
run the
data memory reset (HACCP alarms)
Check, during the equipment operation, that the door remains perfectly closed, otherwise check
the door alignment by acting on the brackets
Check the value set on parameter i1 (door microswitch input polarity)
Check that the door microswitch is correctly positioned
position it correctly if necessary
If the microswitch is correctly positioned, access the electronic card
With multimeter set in Ohm, after disconnecting the microswitch from connector “ID1”, check that there is continuity on the
contact with door closed
If there is no continuity on the contact,
replace the microswitch
If there is continuity on the closed door microswitch but the alarm remains displayed, the cause is the faulty digital input of the
board
replace the board
set the parameters according to the field of use of the equipment
