If the front door is opened (HFD 6 and 7 only), the controller turns off only the lights. The display reads

temperature.

Clear the error by powering off the HFD, correcting the problem, and turning the HFD on again.
Programming using USB drive
With the HFD off:
1. Insert the flash drive in the controller’s USB port.
2. Turn on the controller. The configuration will load in less than 5 seconds.
3. The display will show the configuration code (example: 001h) from the vendo.cfg file.
4. Pull the flash drive out of the controller (controller may remain on).
Circulation Fans
Models HFD000007 and HFDC00002 include a low volume dual air circulation fan system. These fans are
intended to improve internal temperature consistency and help reduce condensation inside the HFD.
Located at the top of the back side of the HFD cabinet is a fan switch that controls the operation of the fan
system. It is recommended that the fans remain “ON” at all times. However, through product testing, it may
have been determined that specific products may require the fans to be turned off. Before turning the fans
off, please consult your Food Quality Manger to determine if you are holding any food products that would
require the fans to be turned off.
TROUBLESHOOTING
If the HFD does not come on:
1. Check that the HFD is plugged in.
2. Check that the electrical outlet has power.
If the HFD does not heat up to the normal temperatures or is not heating properly:
Check for flashing red indicators on the controller and for error codes on the display. Press the button
next to the flashing indicator, and note the error code (example E65, see error code list above). Turn
the controller off, then on, to see if the error is cleared. If the error is not cleared, or periodically
reappears, go to www.vendoco.com, Products, Hot Food Displays to the “Universal HFD Line Technical
Service Manual”, or contact Technical Service at the number on page 2.
