User Interface and Keypad
Here we provide information about the User Interface, Keypad and Appliance Manager connections.
The User Interface and KeyPad are connected and communicate with each other through the J1
connections. The User Interface & Keypad assembly (J4) communicate with the Appliance Manager
(P1). When testing between these components you are searching for LOW voltages as described in the
diagrams below.
This second diagram represents a higher featured oven that does not have the power transformer on
the Appliance Manager. It acquires the low DC voltage from an electronic power supply (SMPS).
Measurements are the same between the User Interface and the Appliance Manager (14 VDC between
J15-2 and J15-4).
