1 FLASH | Symptom: One or both of the Indicator lights on the safety reversing sensors | ||
Safety reversing sensors | do not glow steady. | ||
• Inspect sensor wires for a short (staple in wire), correct wiring polarity (black/white | |||
wire open (broken or | |||
wires reversed), broken or disconnected wires, replace/attach as needed. | |||
disconnected). | |||
• Disconnect all wires from back of motor unit. | |||
| OR | ||
| • Remove sensors from brackets and shorten sensor wires to | ||
