What E02
actually means.
Sensor 2 on Delfield's control reads the evaporator coil. The control uses it to end defrost and to hold the evaporator fans after defrost on low-temperature units. With E02 showing, defrost is no longer ended by coil temperature, and ice can build.

What to do when E02 shows on the commercial applianceKind of codeSensors and probes
A probe is handing the controller a reading it cannot trust, or none at all: a box or coil sensor torn loose from its clip, a fryer probe coated in carbon from oil left too long between filterings, a combi core probe with a kinked cable, or a connector gone green from steam and cleaning chemicals. The unit then runs on, stops, or shuts the heat or the cooling off to protect itself. Letting it cool and restarting it as the manual describes is fair; a probe that still reads wrong sits behind a panel, and that is a visit.

For a Delfield station that runs warm by late lunch, we time the visit to a slow hour so the pans can come out and the rail can be tested empty.

What not to do
E02 is not the air sensor; E01 is. E03 and E04 in Delfield's table point to sensor inputs that are left open on these units.

A booking with a code goes further when it has the code as shown, the model and serial from the data plate, and a word on whether the unit still holds temperature, heats, rinses or spins. With those three, the office can match the likely part to your unit the same day.
