Before removing the processor board, check the following areas:
- If the machine is operating correctly, verify the operation of the hopper in the outputs test
- Turn power off
- Remove the processor board
- Turn power on
- If hopper stops, replace the processor board
- If hopper continues to run without the processor board, replace SSR
If that doesn’t work, try the following steps:
- Replace the processor board with a “known good” one
- If the processor board seems bad, check eBay for replacement or repair service
- If the processor board is good, then replace the motherboard
- To repair the motherboard, use this diagram to isolate the bad trace
