My model 8355 Liftmaster garage door opener is overheating

Customer Question

My model 8355 Liftmaster garage door opener is overheating and cutting power for short time even after a few openings. Could it be the motor capacitor.

it could be that and/or the motor too................if I can ask a few questions

1-) The make and model and/or number of the unit in question and do you have the manual for it?

2-) how old it might be and if you are the original owner

3-) there are 2 safety sensors on your door do they have an amber, or green light that is on steady and not flickering?

4-) can you tell me if you have a working wall control and how many remotes

5-) any flashing lights on the opener and how many times it blinks before pausing? The color of the learn button

6-) has there been any kind of disruption that may have changed the dynamics with this opener....any wiring or perhaps the kids playing there or a recent power outage

7-) are you using ONLY the equipment that came with this opener?

8-) do you have a chain......belt......or screw drive?

9-) what exactly happens when you do click the transmitter?....... the door doesn't move but you hear the motor?......it goes partial way?........reverses?

10-) do you feel that you are capable of making simple adjustments and more than mechanical in making some harder ones if necessary?
