This is a repair service for controller modules, not a replacement part purchase. You will need to ship your defective module to the repair facility, where technicians will diagnose and repair the issue, then return it to you.
The service covers models 325, 328, 329, 331, 334, 335, 337, 341, 425, and 428 with part number 6691432. Common issues repaired include dead power, display failures, non-working gauges, broken connector pins, water or corrosion damage, button failures, hydraulic issues, and specific error codes like two-speed errors or low battery voltage warnings.
The repair process takes 3-5 business days after the module is received. A one-year warranty covers the repair work, excluding lightning strikes, physical damage, and unrelated failures.
If the module cannot be repaired, a refund will be issued minus a 50% repair attempt fee. If the module arrives in working condition, a 30% testing fee plus return shipping applies before refund. Additional modules can be tested for a non-refundable $20 bench fee each. The facility does not work on previously serviced boards or modules with missing parts. Customers are responsible for all return shipping costs.
