T09 control- Main oven control that is self contained.
All relays and inputs connect to this ERC. Basic – Bake
and Broil functions only, NO self-clean.
T012 control- Main oven control that is self
contained. All relays and inputs connect to this ERC.
More functions than T09, like convection and self-
clean.
Machine control- A separate control board that
contains all relays and communicates with User
interface to control all outputs. Located behind
control panel housing.
ERC- Electronic Range Control - an example would be
the T09,T012 controls.

User Interface-

A LOGIC board that interprets
customer input from keypanel.

Daughter board-

This is an auxiliary relay board used
to control lower oven functions on units with T012
ERC.
Tactile – Defines the type of input to control, tactile
controls are switches mounted to the front part of
ERC and are covered with an overlay.

Definitions

GLASS TOUCH- A capacitive glass panel that
transfers key pad touches to ERC or User interface
board. Connected by harness to T012, direct plug into
MACHINE CONTROL board.

Thermal limit switch-

switches provide a safety back-up in case of a
thermal "run-away". Some will reset when unit
temperature cools down, others are "one-shot" and
will need replacement if they open. Check for cause
of over temp!
FAD- Fan apparency device. In previous models, these
were temperature operated devices that would open
a circuit if area got over temp. Now, units use FAD
boards that monitor cooling fan speeds, the control
will shut down operation if fan speed is not within
valid range. The boards will also log a F96,97,98 or 99
code. Operates like a miniature tachometer.
SWO- Single Wall Oven
DWO- Double Wall Oven
These temperature operated
