When a QCS conveyor toaster is turned off, the fan and conveyor motors keep running for five minutes to carry heat out of the unit. The display alternates COOL and DOWN during that time and then shows OFF. Star commercial appliance display · also shown as COOL, DOWN What to do when COOL DOWN shows on the commercial appliance ### Kind of code Mode, not a failure Nothing on the unit has broken; the controller is reporting a state it chose or one somebody set. A defrost pauses cooling for a scheduled melt and shows a warmer air reading for a while, a combi asks for a delime or runs its clean cycle and locks the door until it ends, a dish machine or a laundry machine sits in energy save between busy periods, and a door-open reminder beeps after a long delivery. No part is needed: letting the cycle finish, or the key sequence in the manual, brings the unit back. ### Usually leads to No repair Leave the toaster plugged in and let the five-minute cool-down finish. ### Shows up as Commercial Appliance Error Code on a Combi, Fryer, Dish Machine or Laundry Display A commercial appliance error code appears as letters or numbers on a combi, fryer, reach-in controller, dish machine or laundry machine display, or as a flashing light or an alarm tone. ### Make Star Star equipment is usually checked in the slow window after breakfast, while the cooking surface cools. ### Source Star Holman QCS2 / QCS3 conveyor toaster owner's manual (star-mfg.com) Star Holman QCS2 / QCS3 (QCSe) conveyor toasters with the LED readout. ## Before you book, in this order. Each step comes from Star's own guidance for COOL DOWN on its commercial appliances. Follow it to the end: the last card says whether this is a visit. 01 Leave the toaster plugged in and let the five-minute cool-down finish. 02 Keep hands and cleaning cloths off the conveyor while it is still moving. 03 If COOL DOWN never ends, or the fan stops early and the housing gets very hot, book a visit. ### Cleared? The code is gone from the controller, the box pulls down to its set point and holds it, the vat or the cavity reaches temperature and recovers on schedule, the rinse hits its heat and the drum finishes its spin, all without a new part. If the same code comes back within a week, or during the next busy shift, mention it when you book. ### What not to do COOL DOWN is normal shutdown behavior, not a sign the toaster failed to turn off. Unplugging it early skips the cool-down, which is harder on the motors and elements. ## What you may notice with it. The commercial appliance problem COOL DOWN tends to arrive with. Answer these at the commercial appliance before anyone is booked.

Leave the toaster plugged in and let the five-minute cool-down finish. ### Why does my Star toaster keep running after I press off? It is cooling itself. The fan and conveyor run for five minutes with COOL and DOWN on the display, then the unit shows OFF. ### Can we unplug the Star conveyor toaster during COOL DOWN? It is better not to. The cool-down moves heat out of the toaster so the motors and controls are not sitting in it. ### When is it safe to clean a Star conveyor toaster? Wait until the display shows OFF and the toaster has cooled to the touch before wiping it down. --- **[Read on the site: Star COOL and DOWN alternating: the conveyor toaster is cooling after shutdown](https://commercialappliancerepair.center/error-codes/star-cool-down/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
