SONAR BOARD

Part 12-2376-21 is a direct replacement listing for Sonar Board in many repair scenarios. Order by part number to avoid mismatches. Control boards coordinate timing and output commands across the machine. Stable control signals are essential for repeatable cycles and safe operation. Common complaints include random resets, intermittent operation, or error code. If the issue is intermittent, look for vibration-related wear marks and connectors that shift under load. Confirm the symptom first, then inspect the part location for wear, corrosion, cracks, or looseness. Once the underlying cause is addressed, error code complaints usually reduce or disappear. After replacement, run a short test cycle and watch for leaks, vibration noise, or recurring faults. Reinstall carefully so nothing pinches, rubs, or binds once the unit is back together. Once the root cause is corrected, cycle behavior should stabilize and performance should return to normal. Verify any model compatibility notes shown on the product page before completing the order. Keep the removed part until final testing is complete so you can compare fitment if needed. If the machine was down for a while, take the opportunity to clean the area around the repair.
