Possible Causes
Motor receiving power but mechanically jammed, seized piston, stripped gear preventing rotation, low voltage to motor
How to Fix / Troubleshooting
Safety first: Unplug the unit before touching the motor or gears. Close inlet if disassembling the valve.
- Check voltage: Verify the transformer output is correct (typically 24 VAC) and that the motor is receiving proper voltage.
- Inspect for binding: Remove the motor from the gear train and see if it runs freely when powered (use caution and follow manufacturer guidance).
- Service piston and seals: If the valve is hard to turn by hand, remove and replace the piston and seal pack.
- Replace motor or gears: If the motor hums but does not turn even when removed from load, replace the motor. If gears are stripped, replace the gear set.
