AJ Antunes/Roundup VCT-200 toaster showing CHEC on display
Our VCT-200 display showed CHEC … anyone know what that means?
Concerned that there may be an issue with the unit, it has shown up on a few separate occasions now.

“CHEC”
The electrical compartment ambient temperature is above 140° F (60° C). All
heaters will shut off. Check for proper air flow.
The unit is overheating. Check the axial fan, it may be faulty or stopping. Part # 4000202

Also verify that the cooling fan is not installed upside down. installing a cooling fan upside down could cause the fan to suck in hot air that is coming from platen into the control compartment. The heat shield on top of the unit is made so that the air being blown by the fan is drawn through the heat shield to keep cool enough to touch, but if the fan is backwards then the fan will be doing the opposite and blowing the hot air into the control compartment. The older fans had a brown label on them, the brown label fans should have the label facing down during install, but the new fans have a blue label as shown on techdanc’s post, which the label should be facing up. So when someone replaces the fan they think the label should face the same way, but in fact you need to locate the arrow on the fan and points in the direction of air flow and verify that the fan will blowing air out the control compartment instead of in to the control compartment. Common mistake .
