Help with Allstar gaurage door opener
I have a problem with Allstar garage door opener. Yesterday evening it spontaneously opened garage door. I closed it using the open/close switch. Then I unplugged power cord to make sure it does not happen again. This morning when I plugged-in power cord, the light came on but door opener does not react to the on/off switch any more. Could anyone, please, help with ideas/ checks/ suggestions?
Thank you in advance!
