How to troubleshoot a Roundup Toaster when the display flashes “HI” and buns don't toast?
- RRonald MacdonaldAug 30, 2025
If the Roundup Toaster control display flashes “HI” continuously and the buns are not toasting properly, it could be due to a loose platen thermocouple connection on the control board or an open platen thermocouple. Try re-securing the platen thermocouple connection to the control board. If the display continues to read “HI”, check the thermocouple for continuity. If problems persist, it's recommended to contact your maintenance person or an authorized service agency for assistance.
