2 liftmaster openers died - no motor sound, no lights
Hi I have two LiftMaster garage door openers on my 2-car garage (openers are about 10-year old, it's the age of the house). They died a week ago simultaneously. I left the house in the morning when I closed the doors using the remote on my car, when I got home at night, they both died. Now when I try to access it through either the wall panel, or remotes, there is only a "click" sound on the unit, no motor action, and the lights on the openers (two 75-watt light on each opener) are dead too.
The indicators on both unit flash 5 times, which seem to indicate either motor overheat or RPM sensor problem. Pulled the plug for an hour and connected back, nothing changes.
I'm looking for advices... what could be wrong, and how to troubleshoot them... I know that there is probably no good news at this point :(
