When a unit shows worn part issues, the Txv is often evaluated; part 16-1091-21 is the replacement reference. Order by part number to avoid mismatches. Confirm the symptom first, then inspect the part location for wear, corrosion, cracks, or looseness. Check nearby components for secondary damage so the new part isn’t stressed immediately after installation. Replacing Txv can resolve downtime when the fault is confirmed at this component. A clean, correctly seated replacement often resolves recurring issues caused by vibration or wear. Replacing a worn component early can prevent secondary damage to nearby parts. Common complaints include downtime, worn part issues, or repeat failure. After replacement, run a short test cycle and watch for leaks, vibration noise, or recurring faults. Disconnect power before service and document the original routing or hardware positions with a quick photo. A correct-fit part improves reliability and prevents small issues from becoming bigger failures. 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.
