We have a three zone central cooling/heating system with six of these ARD actuators. Two of our actuators stuck in the close position. It was a easy five minutes job to replace each actuator. But make sure you have a 1/8 inch hex wrench which is required to replace the actuator.

Very pleased with product. If there is one thing I could change, it would be to make it capable of full disassembly so that a broken spring could be replaced.
