Product Description

PCB ASSEMBLY Specifications

This main control board acts as the central hub for microwave operation, managing power distribution, sensor input, and all cooking functions including heating, lighting, and turntable movement. It ensures precise temperature and timing control for efficient performance. Replacing a faulty board restores reliable operation and resolves issues such as unresponsive controls, power failures, or inconsistent heating. Installation is straightforward—disconnect power, remove the old board, and secure the new one according to your appliance’s instructions.

Sorry, we couldn't find any existing installation instruction that matched.
Numeric display was malfunctioning. Lit segments were dim and some non-lit segments were flashing faintly.
1. FIRST -> UNPLUG THE MICROWAVE!
2. Remove two screws (left & right most) at top to remove the vent grill.
3. Open the door and tilt top of vent grill out being careful of to not break the two mounting tabs.
4. Remove screw at top of the keyboard / display assembly (hinges at bottom).
5. Note the position of wires (take a photo) and remove 5 wire connectors.
6. Place keyboard / display assembly on a towel, face down.
7. Compare old PCB with new PCB and verify they are have the same part number.
8. Remove ribbon / flex cable (pull locking bar), and four screws to remove the PCB.
9. Install the new PCB, tightening the four screws and reinstalling the ribbon / flex cable. Flex cable must be straight and press the locking bar.
10. Re-install the 5 wire connectors using your photo.
11. Re-install the keyboard / display assembly and secure with the single screw.
12. With the door open, re-install the vent grill being careful to insert the two upper tabs.
13. Reinstall the two screws holding the vent grill.
14. Plug in the microwave and test.
In my case, the vent grill tabs were broken (one was broken prior to disassembly and the second damaged upon re-install).
Thus, I secured the vent grill using two plastic tie wraps inserted though the screw holes.
Total time: 30 minutes.

The digital readout on the LG microwave started flickering and then finally just went blank.
I removed the overhead heat vent removed the screws off the digital panel board and pushed left on panel. Came off and then I removed the 8 screws holding the circuit board in place. Removed all the connected cables, then proceeded to install new circuit board. Reversed process. Microwave is brand new again.
