Before removing the processor board, check the following areas:
- Verify that the wires to the hopper motor are connected
- Verify that the roll-pin is good
- Test for 110 VAC across J/P l9-11 & 12
- If 110 VAC is missing, then trace back for a broken connection
- If 110 VAC is good, then replace the hopper SSR and test
- Check for obstructions in the hopper
- Use another hopper to determine if the motor seems bad
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
- If the motherboard and processor board are good, then use this diagram to test for wire continuity
