– 22 – Component Access Chart W ARNING: The oven is heavy and requir es two people to remove fr om the cabinet or wall opening. Car e should be taken when removing and installing. Sharp edges may be exposed when servicing. Use caution to avoid injury.
– 23 – Oven Removal / Partial Removal T o remove the oven fr om cabinet or wall opening: W ARNING: This oven requires 2 people for complete oven removal. Grasp the bottom of the oven at the front and r ear on each side. Caution: Do not use the oven handle to lift or lower the oven.
– 24 – Door Assembly W ARNING: A microwave leakage test must be performed any time a door is removed, replaced, or adjusted for any reason. (See Diagnostic and Service Information .) Door Removal Caution: Do not close the door beyond the door remov al position.
– 25 – Control Panel Assembly The control panel assembly consists of an outer control panel and an inner contr ol panel bracket . The outer control panel contains the contr ol, display, and selector circuit boar ds. The power and relay circuit boar ds, and the low voltage transformer are attached to the control panel bracket .
– 26 – T o remove the power boar d: Remove the control panel assembly. (See Control Panel Assembly .) Disconnect wire harnesses fr om the power board at locations CN4, CN7, and CN11. Remove the 4 Phillips-head screws that attach the power board to the contr ol panel bracket .
– 27 – T o remove the contr ol board: Remove the control panel bracket . (See Control Panel Assembly .) Disconnect the 20-pin harness connector from the display board. Disconnect the wire harnesses fr om the selector board at locations CN9 and CN13.
– 28 – T o remove the selector board: Remove the control panel bracket . (See Control Panel Assembly .) Pull the dial straight out from the contr ol panel. Disconnect wire harnesses fr om the selector board at locations CN9 and CN13. Disconnect the wire harness fr om the control panel at location CN14.
– 29 – Caution: Do not twist the lamp. The oven lamp is a 130-V AC, 20-watt lamp (Part # WB08X10050). It is a plug-in type lamp.
