Garage door opener stops working after 3 or 4 uses
I get 5 codes flashing(rpm sensor or overheated).
I unplug and 2 hours later or so...It will work again for 3 or 4 times.and then the 5 flash code again.
I lubricated track and rollers and the chain for the opener. Garage door seems to be smooth enough and nothing sticking. It is 2001 Chamberlain 1/2 HP opener. It is pulling up a double garage door. I had switched this 1/2 HP opener from my single garage door because the original one on the double garage door was sporadic and just going up a few inches and stopping.
The 1/2 HP on the single garage has been used maybe 40 to 60 times in its 10 year life. It was working fine on the single garage door before I switched to the double car garage.
I've adjusted the upward force and downward force and have tried it on 3,5,7, and 9 settings for both upward and downward.
Opener will work fine(slide back and forth) if the garage door is not attached and pulled.
Optical sensors seem to be working ok.
