I have the same problem. Door does not open or close when press the push button and/or transmitter. The light flashes 5 times. Manually open or close the door is ok. On the manual troubleshoot, it says it's either the opener is overheated or it's on vocation mode. I don't know how to switch of vocation mode. Is it possible the thermal sensor is broken?

SOURCE: How do I remove the lens cover for the light on a Guardian garage door opener 21230L?

Not sure about the Guardian, but it should be in the installation manual which can be downloaded, if you don't have the original. On my "Linear" brand, you just have to press the plastic cover at the right place and it releases.

Trace circuit, back through the wiring, through the switch, and back to the source, using a meter.

if your saying that the light on door opener housing is flashing then stopping after a few moments , this is a sign of a fault in door safety's , either the door has to much friction now to move or beam detectors have sensed a problem

Unplug the opener and remove the bulb. Use a small screwdriver to pry out on the center contact in the socket. Replace the bulb and plug in the opener. Be sure to use only standard incandescent bulbs.
