This morning my LiftMaster MyQ started flashing Red and Yellow. Having a hard time pinpointing something on the internet.
What model of gateway are you using? Is it the 828LM or 821LM?
828LM. Called up garage door place and they said it is related to the opener. Going to get it serviced shortly.
From the 828LM/888LM troubleshooting guide:
If yellow and red LEDs are blinking slowly, the control panel is not compatible with your garage door opener.
If the yellow and red LEDs are blinking quickly, the control panel is charging, and may take up to 5 minutes to become operational.
Found out it was due to the fact the circuit board must’ve been going out on the opener. Got it all taken care of now. Your reply was helpful for troubleshooting the issue.
