CURTAIN SENSOR

For technicians: Curtain Sensor is supplied as part 12-2436-22 for replacement during troubleshooting. Use the part number as the primary identifier when ordering. Sensors and probes feed readings back to the control logic to manage timing and protection. Incorrect feedback can cause cycling changes even when mechanical parts are fine. Common complaints include premature shutdown, incorrect reading, or long cycle. Check nearby components for secondary damage so the new part isn’t stressed immediately after installation. Confirm the symptom first, then inspect the part location for wear, corrosion, cracks, or looseness. Once the underlying cause is addressed, long cycle complaints usually reduce or disappear. Recheck fasteners and connectors after the first run-in cycle to confirm everything remains tight. Disconnect power before service and document the original routing or hardware positions with a quick photo. 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.
