Safety Device Open Circuit
An external safety device (photo eye, edge) has an open circuit.
1. Check all safety device wiring. 2. Verify jumpers are in place if no safety devices are installed. 3. Test each device with a multimeter.
Safety Device Short Circuit
Safety device wiring is shorted.
1. Disconnect all safety devices. 2. Add back one at a time to find the short. 3. Repair or replace damaged device.
Control Circuit Fault
Open/Close/Stop control circuit has a fault. Wall station or external control is stuck or shorted.
1. Disconnect external controls. 2. If error clears, troubleshoot the control wiring. 3. Check for water damage to wall stations.
Motor Start Fault
Motor did not start or did not reach running speed. Capacitor failure, motor winding failure, or loose connection.
1. Check motor capacitor with a meter. 2. Check motor terminal connections. 3. Verify power supply voltage. 4. Spin motor by hand to check for seizing.
Motor Overload
Excessive motor current detected during travel.
1. Disconnect door and test operator unloaded. 2. Check springs, balance, and track. 3. Verify correct operator HP for door size.
Travel Not Set
Travel limits have not been programmed.
1. Enter programming mode. 2. Run door to full open — set limit. 3. Run door to full close — set limit.
Board EEPROM Error
The onboard memory has become corrupted. Power surge or component failure.
1. Try a factory reset. 2. If error persists, replace the control board.
RSX Standard Drive
Residential operator (RSX, Legacy 800 series). Compact unit with LED on the back panel.
Where to look: Single LED visible on the back panel of the unit when looking up from below. NOT the learn button LED on the side.
Normal / Standby
No fault. Operator is ready and waiting for a command.
No action needed. This is normal operation.
Safety Sensor Fault
Safety sensors are not connected, misaligned, or have a wiring issue.
1. Check sensor wiring. 2. Align sensors. 3. Verify sensor LEDs are lit.
Motor Thermal Protection
Motor has overheated and the thermal protector has tripped.
1. Wait 15-20 minutes for the motor to cool. 2. Check door balance. 3. Reduce cycle frequency.
No Power
No power reaching the control board. GFCI tripped, breaker off, or power cord unplugged.
1. Check outlet power. 2. Check/reset GFCI. 3. Inspect power cord. 4. Check internal fuse if applicable.
