What COOLING DOWN
actually means.

When the back/off key is pressed on a hot HhC, the heat shuts off and the display shows COOLING DOWN with the chamber temperature. The oven moves on to Oven Off once it drops below 150°F. The Single Batch shows the same words after it is switched off, and TurboChef says not to start cleaning until they are gone.

What to do when COOLING DOWN shows on the pizza oven

Before you book,
in this order.

Each step comes from TurboChef's own guidance for COOLING DOWN on its pizza ovens. Follow it to the end: the last card says whether this is a visit.

01

Leave the oven plugged in and switched on at the breaker so the fans can finish cooling it.

02

Wait for the display to change to Oven Off before starting any cleaning.

03

On a Single Batch, the manual allows leaving the door open and placing a tray of ice inside to speed it up.

Cleared?

The code has left the display, the decks or the tunnel come up to the set heat and hold it through a full service, the belt keeps its speed and the blowers run steady, all with no part changed. If the same code returns within a week, or on the next busy night, say so when you book.

What not to do

COOLING DOWN does not mean the oven has broken; the fans running after switch-off are there to protect the components. If the oven cools, shuts down or changes screens on its own during service, that is a different entry in the Single Batch manual and points at the display.

What you may
notice with it.

The pizza oven problem COOLING DOWN tends to arrive with. Answer these at the pizza oven before anyone is booked.

All problems

No repair indicated

Nothing to repair.

No part of the oven has failed; the display is reporting a state someone chose or the oven entered on its own. A cool-down keeps the blowers turning after the heat is off until the cavity or the tunnel has dropped to a safe level, an energy save setting lets the decks sag between rushes, and a menu lock stops anyone on the line from changing the bake times. No part is needed: letting the cool-down run out, or the key sequence in the manual, brings the oven back.

Questions
about COOLING DOWN.

Can I clear COOLING DOWN myself?
Leave the oven plugged in and switched on at the breaker so the fans can finish cooling it.
How long does a TurboChef conveyor stay in Cooling Down?
Until the chamber drops below 150°F, when the HhC switches itself to Oven Off. How long that takes depends on how hot it was running and the air in the room.
Can I unplug my TurboChef while it says Cooling Down?
Better not. The fans stay on during cool-down to protect the parts inside, and TurboChef also warns against using the emergency stop key as an everyday off switch.
Why can't I clean the TurboChef during Cooling Down?
The cavity is still hot enough to burn, and TurboChef's cleaning steps begin only once the display no longer reads Cooling Down.

Back to your everyday

Still showing COOLING DOWN?

A booking with a code goes further when it has the code copied as shown, the model and serial from the rating plate, and a note on whether the oven still lights, heats or moves its belt. With those three, the office can match the likely part to your oven the same day.
