3 GENERAL
The 500 Series includes five HBL5x (30") and two HBN5x (27") built-
in wall ovens. Models have thermal oven cavities and/or Euro-
convection (convection with ring element) cavities. The lineup
includes a field-assembled combination model with a 120V
HMB50152UC microwave oven component.
All models are stainless and have heavy-duty metal knobs for
selecting the cooking mode and temperature, as well as white LED
displays. The wall ovens are designed to be installed flush with
cabinetry.
The control panel and door skins on the stainless models are made of
grade 439 stainless steel, which is magnetic.
3.1 Recap of Functional/Technical Changes
 Cooling fan: now operates with a variable speed protocol.
Hall effect sensor has been eliminated, and thermal limiter
(HTC) has been added.
 Power supply: now located on the control module (relay
board) rather than as a separate component.
 User interface: no longer separate user interface software;
the control module drives the user interface. LED-based
display with capacitive touch panel managed by a separate
touch control module (TCM).
 Daughter board (double ovens only): populated with relays to
operate the lower oven.
 Ventilation: air flows up through each door, then back out
over each door as air exits the appliance; some air is pulled
into the unit at the lower vent area under the appliance.
 Lighting: Soft lighting is standard on all models. Double oven
lighting is not independent; lights operate concurrently.
 Temperature control: now a two-point control for all modes
rather than a PID control for all modes.
