Genie Excelerator® Series Garage Door Opener Self-Diagnostic Troubleshooting

The Genie Excelerator® Series screw drive garage door openers have a status light on the powerhead that will blink if an issue arises that helps diagnose the issue. This diagnostic light is on Excelerator models: H8000, H8000-07, H8000D, ISD990, ISD995, ISD1000, PRO99, PRO99-21C, PRO99FN, and CMD9900.

Genie Excelerator garage door opener self diagnostic indicator light
The status LED indicator light is located under the lens cover. The Green LED light will turn on, then off when power is applied to the garage door opener. If the green indicator light stays on- contact Genie customer service. If it is blinking, you can start by using the diagnostic blink codes below to troubleshoot. 

 

Below is a video showing an example of what you would see if the indicator light was blinking on your Excelerator garage door opener 5 times. This would indicate the Safe-T-Beams could need replaced. (Safe-T-Beams 37220R for the Genie Excelerator)
